Every photographic camera you ’ve ever used in your life sentence has a lens of the eye that focuses incoming photon on to a light - sensitive surface . But in the future tense , cameras might not need electron lens at all , and this Bell Labs prototype illustrate how this could be done for cheap .
Technology Review reportsthe Bell Labsconcept , which relies on a method for assembling images called comprehensive detection ( or comprehensive imaging ) . The basic principle states that any information limit with spate of interchangeable mensuration will contain a plenty of lapping — and therefore redundant — information . In theory , then , if you take better measurement , you could get substantively standardized results more expeditiously .
The epitome design consists of two different parts : An aperture assembly and an image detector . The aperture gathering is an LCD , which appropriate light to pass through at point of varying size and position . The sensor , in this compositor’s case , is a single - pixel , three - color chip .
To take a photo , the tv camera records the Inner Light that blow over through a random sampling of compass point on the aperture assembly , and utilize processing to ascertain the correlation between the dissimilar data , after which , it can reassemble the effigy .
While this whole mental process take a bit longer than we ’re used to by today ’s photographic standards — it needs to do the combining weight of thousands of shutter movements rather of a single shutter — it ’s unbelievably efficient when it come to materials and components . Indeed , the Bell Labs prototype was assembled using off - the - shelf material .
conceive of a photographic camera without optics and hardly any pixel on the sensing element . It could be incredibly cheap . The main problem will be getting the image quality and performance of such a camera up to snuff , which is all too far off . [ arxiv.orgviaTechnology Review ]
