Abstract

Computational imaging apparatus are modern systems that consist of generalized optics and image processing capability. The term ‘computational imaging’, also known as ‘computational photography’, describes the emerging field of optical systems in which an image is not formed by a lens and simply sampled onto the detector. Rather, the process of image formation is facilitated by both the power of the optical elements and the computational processing of the sampled light signal. Such an imaging system integrally incorporates optics, optoelectronics, and signal processing. These systems can be optimized to greatly increase the performance of the imaging apparatus that utilizing solely traditional optics. By introducing computation into spectral imaging, breakthroughs could be achieved in imaging speed, resolution and spectral accuracy.
