| Outline of Final Research Achievements |
In conventional optical imaging based on optical imaging by a lens, the size of the optical system increases in proportion to the amount of measurement information. As a technique to solve this problem, computational imaging combining optical encoding of image information and digital decoding of the coded image has been studied.
In this research, we designed and demonstrated the computational imaging using coded aperture with three dimensional structure. We clarified that angle and wavelength selective coded imaging can be implemented by using an optical element having a three-dimensional structure as a coding aperture. By combining with compressive sensing, we demonstrated that wide field of view, high resolution imaging can be realized with small optical system.
