[ 0023 ] fig1 illustrates a perspective view of three dimensional objects . from this perspective view , a block 15 in the foreground can easily be detected against the cylinder 16 in the back ground . [ 0024 ] fig2 illustrates a perspective view of three dimensional objects when the object in the foreground is transparent . the transparent block 19 enables light from the background including the cylinder 16 to be transmitted through it . [ 0025 ] fig3 is a second view of the objects of fig1 . the same objects from fig1 are here observed from a different perspective . the cylinder 16 is unobstructed but now the pyramid 17 is obstructed by the block 15 . [ 0026 ] fig4 are the same objects where that in the foreground is transparent . the transparent block 19 enables the observer to see the back ground which in this case is the pyramid 17 . the point of these simple three dimensional views is to illustrate that the problem of rendering a non - transparent object invisible is a very difficult one . one image of the background will not be adequate because the back ground is totally dependent upon the observers position . the following diagrams and ensuing description illustrate how the background of the object from many perspectives can be simulated simultaneously . [ 0027 ] fig5 illustrates an array of receiving and sending surfaces on two sides of an object . a first side of the object 24 has an array of hexagonal sending and receiving cells affixed to it . a second side of the object 23 has an array of receiving and sending cells affixed to it . light from a background object 30 is incident upon many cell surfaces on the first side of the object . first incident ray 31 is some such light from 30 . it is incident upon the bottom surface of a cell . the cell surface ( not shown ) consists of a photoelectric material ( such as an led array or a ccd array ). information about this light is collected electronically and sent to the corresponding sending surface on the opposite side of the object which emits a first corresponding light ray 32 closely resembling the color and intensity of the first incident ray 31 light . the sending surface ( not shown ) consists of a photo emitting material ( such as a multichromatic led array ). similarly a second incident ray 29 is light from back ground object 30 . its trajectory is different from that of 31 and it is therefore incident upon a totally different surface . the surface that 29 is incident upon corresponds to a surface on the opposite side of the object — such that when the second corresponding ray 28 is emitted , its trajectory is the same as that of 29 . the color and intensity of 28 are likewise engineered to resemble that of 29 . in actuality , many additional surfaces would concurrently be receiving light from 30 and the process of collecting and reproducing that light is likewise repeated many times by many incident surfaces and corresponding surfaces . this is because an observer may be at any observing angle . background object 30 will need to be viewable at all of these angles . note that one observer at 32 can “ see ” 30 and also an observer at 28 can “ see ” 30 . similarly , a second background object 26 emits rays that are incident upon many receiving surfaces , a third ray 27 being one such ray . the surface that receives 27 collects color and intensity information and sends it to its corresponding surfaces which emits a third corresponding ray 25 designed to emulate 27 in trajectory , color and intensity . [ 0028 ] fig6 illustrates a single collecting and receiving cell with 7 surfaces . each cell has multiple surfaces to collect incident light from different trajectories . each surface can collect information about color and intensity . ( photodiode and ccd are examples of materials which can from these surfaces .) surfaces include walls such as 34 , 35 , 36 , 37 , 39 , and 33 and the bottom 38 . in practice the whole cavity of the cell is filled with a transparent substrate . this improves stability of the cell and protects the electronic components while also providing a refractive index higher than air for improved efficiency . said transparent substrate may protrude out side of the cell to form a convex lens for improved efficiency . [ 0029 ] fig7 is a diode receiver and diode sender flow chart . the flowchart represents a single surface of a single cell on a first side of an object , a power source and a single corresponding surface on a second side of the object . a light beam 40 is incident upon the surface . a green photodiode 43 receives photons within a first wavelength range , a red photodiode 46 receives photons within a second wavelength range , and a blue photodiode receives photons in a third wavelength range . intensity of the incident wavelengths varies the electric output of the respective photodiode . the intensity is used by the variable power sources to correspondingly power the surface on the second side of the object . variable power sources 44 , 47 , and 50 receive intensity information from their respective photodiodes and sends power to a respective corresponding leds . the green led 45 sends green light 54 , the red led 48 sends red light 53 and the blue led 51 sends blue light 52 . in this way , the color and intensity of the light incident on the first surface is reproduced on the second surface . [ 0030 ] fig8 is a ccd receiver and led sender flowchart . the flowchart represents a single surface of a single cell on a first side of an object ( the ccd ), a power source and a single corresponding surface on a second side of the object ( the led array ). light 58 passes through a color band filter 59 and then is incident upon the ccd array 60 . at 61 , 64 , 65 , and 68 , filters are used to split the signal from the ccd into three bands representative of color . intensity of each band is used to control the power sources output to the correspondingly colored led . on the second side of the object , the 63 green led produces green light 57 , the red led 67 produces red light 56 and the blue led 70 produces blue light 55 . these light outputs on the second side of the object combine to closely resemble the color and intensity of the light which was incident on the first side of the object . [ 0031 ] fig9 illustrates how the seven surfaces of one cell correspond to seven surfaces located in seven different cells . a first side of an object 105 has one cell mounted on it . a first incident ray 79 strikes the bottom of the cell ( not shown ). this causes the corresponding bottom surface ( the reverse side of 81 ) to produce a corresponding ray 83 . ray 83 resembles the trajectory , color and intensity of ray 79 . likewise 73 is a ray incident upon surface 71 which causes a cell surface 75 on the second side of the object to produce a corresponding ray 77 on the same trajectory with similar color and intensity . each other surface of the cell on 105 has a corresponding surface on the second side of the object . surface 89 corresponds to surface 91 . surface 97 corresponds with surface 95 . surface 97 corresponds with 99 . 101 corresponds with 103 . 85 corresponds with 87 . [ 0032 ] fig1 is a diode receiver and diode sender flow chart in a first state . a multistate vibrator switch causes diodes on the first side of the object to at like photodiodes by reverse biasing . likewise the diodes on the second side of the object are forward biased to act like leds . this causes light to be received on the first side of the object and emitted on the second side of the object . [ 0033 ] fig1 a is a diode receiver and diode sender flow chart in a second state . the multivibrator switch causes the diodes on the first side of the object to be forward biased , making them act like leds . likewise the diodes on the second side of the object are reversed biased to make them act like photodiodes . in this second state , light is received by the diodes on the second side of the object and emitted from the first side of the object . rapidly switching the bistable multivibrator switch enables the same leds to operate as both light receivers and light senders alternately . [ 0034 ] fig1 are the seven receiving surfaces corresponding to the seven sending surfaces of one cell . the identical cells of fig9 are in this figure operating in the reverse . light received by surfaces on the second side of the object is reproduced to be emitted on the first side of the object [ 0035 ] fig1 demonstrates how grid coordinates can be used to calculate how sending and receiving surfaces should map to on another . note that once the relationship of each of the sides are know , each cell surface can be mapped to find its corresponding cell surface . on a rigid body , the relationship between cells remain intact . once the surfaces of each cell are mapped to one another , their relationship to one another doesn &# 39 ; t change and can be hardwired . the surface that the 119 beam is incident upon describes the surface from which the corresponding light beam 121 must be sent to have the same trajectory .
