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.

To obtain a number of advantages in fabrication
testing and alignment
many designs in which spherical mirrors replace classical Cassegrain-form aspheric mirrors are present in the literature. However
spherical mirrors suffer from substantial spherical aberration and thereby require some form of corrector group. But in this case
the question encountered is that of making the basic optical configuration more complex. In this paper
a new design based on Cooke corrector group is presented for eliminating spherical aberration
which is believed to provide higher performance with less complexity than previous approaches. Besides
the cost and fabrication period will be extremely decreased. The telescope system using corrector group here can achieve good optical performance with f# of 10
