Based on reflective liquid crystal spatial light modulator (SLM)
a new foveated optical imaging system is proposed. High quality imaging can be realized at any region of interest (ROI) within the field-of-view (FOV) by utilizing the SLM to correct the aberration of different regions dynamically. A reflective cassegrain optical structure is proposed
which is designed
optimized and matched with the reflective SLM to construct a more practical foveated imaging system. This reflective imaging system has a large aperture so that enough light can reach the image plane. It also makes the total length of the system shorter and therefore more practical. We also simulate and analyze the system. This kind of foveated optical imaging system can be applied in wide FOV imaging aspects to reduce bandwidth and optics complexity
and to achieve weight reduction and miniaturization. 2010 Copyright SPIE - The International Society for Optical Engineering.
