1. A method of generating a representation of an internal structure of an object, the method comprising the steps of: providing radiation that is arranged to traverse through at least a portion of the object; receiving the radiation from different angular directions by an optical element suitable for focusing the radiation from the different angular directions onto a, or a respective, sensor; thereafter forming a radiation exposure pattern using the optical element, wherein a location of the formed radiation exposure pattern relative to the optical element is chosen such that the radiation exposure pattern comprises information indicative of the propagation directions and intensities of component radiation that forms the radiation exposure pattern; and calculating the representation of the internal structure from the radiation exposure pattern; wherein the method is conducted such that the radiation exposure pattern corresponds to a respective point of view of the object.
