"Made up of n pieces of independent lenses" to advertise their mobile footage

It seems like we're all used to it. Mobile phone manufacturers to "composed of N-piece Independent Lens" to advertise their own mobile phone lens, however, the multiple lens design in improving the quality of photography, but also increased the volume of the lens, so that some mobile phone cameras must highlight the overall mobile phone can be assembled in the Can such lenses be integrated into wearable devices? Not only is the lens volume a problem, but it also increases the weight. As a result, American company Rambus developed a lens that does not consist of lenses.

The essence of the lens, according to MIT Marvell Review, is a grating-etched sensor. The sensor is etched into a spiral grating, and when the light passes through the sensor, the sensor can collect light from all directions to obtain a distorted image. Rambus has made an algorithm to restore distorted images to the original image. The lens is 0.2 millimeters thick and can be photographed with the highest 128x128.

Of course, 128x128 pixels are far worse than your cell phone lenses, but the sensor has the advantages of being miniature, inexpensive, and lightweight, and is expected to be used in safe and wearable equipment. Perhaps as time progresses, more high pixel miniature lenses will emerge.
