1. An imaging apparatus, comprising: a broadband light source configured to illuminate an object to be imaged; an objective lens module having an objective lens and a hologram lens configured to focus the broadband light reflected from the object, wherein the objective lens module has a chromatic aberration that separates focal planes of different wavelengths of light, each focal plane having a different magnification; a two-dimensional image sensor configured to capture image data of the object; a two-dimensional color filter array configured to filter light reflected from the object before reaching the image sensor, wherein the filtering comprises transmitting only one band of wavelengths at certain positions in the array, and at least two bands of wavelengths are transmitted over the array; a range finder configured to determine a distance of the object from the image sensor; and a processor configured to construct a luminance plane containing an image of the object by correcting the magnification of the images for each of the different wavelengths such that each image of the object has the same height.
