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.
