Abstract

A few important corollaries of asymmetric apodized point spread function like the strehl ratio (SR), the total transmission factor (r) and the half power diameter (HPD) have been investigated by introducing three level asymmetric pupil filters. For various amount of amplitude apodisation, we have observed that as semicircular ring width increases the value of above corollaries decreases and also we have evaluated half power diameter with lower values than that of airy case for higher degree of apodisation. This study aims high resolution or to improve selected aspects of imaging performance of the optical system.
