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.

On aviation mapping
compression image maybe not decode because of wireless transmission interference. UEP(Unequal Error Protection) scheme is put forward about layer and block structure of JPEG2000 image compression method
flexibly enhances local reconfigurable image's quality which is in favor of identifier in the region of interest. 2008 IEEE.
and realizes three degrees UEP of data block
data header
image data via various degrees correction-coding under the condition of obstruct
naked and shade. BCH
RS and Hamming coding are simulated
and image decoding success rate and image's quality are analyzed according to different coding and ROI (Region of Interest) in the Gaussian white noise model and rayleigh fading model. Results shows that the method we putted forward roughly improves decoding success rate
at the same time
almost not increasing bandwidth
