Abstract

Spatial resolution of CCD imaging spectrometer is deteriorated by cross talk between the elements. Some examples of such a cross talk of CCD elements is shown, and the deteriorated spatial resolution is analyzed. Eye system of some biological things utilizes such a cross talk positively to improve the performance. How to improve the performance? The function is called lateral inhibition. The concept and function of the lateral inhibition is applied to improve the deteriorated performance of CCD imaging sensor. The results of analysis and simulations of the improvement by lateral inhibition are shown. Furthermore, it was clarified that this technology can be applied to synthesize high quality CCD imaging system.
