Experimental Studies on Improved Vector Extrapolation Richardson-Lucy Algorithm Used to Realize Wave-front Coded Imaging

Athermalization of infrared continuous zoom optical system based on wavefront coding

“…The infrared optical system athermalisation is well realized [9] . n Hx y   (10) Where y is coding image of wavefront coding imaging system, H is the degenerate operator os the PSF, x is decoding image, n is system noise. Decoding the intermediate image of wavefront coding imaging system is equivalent to finding x given H and y.…”

“…For this condition, Lucy-Richardson (L-R) is used to solve the above equation. The decoding image x is obtained under the condition that the noise is effectively suppressed [10] . The images of the traditional system at different focal lengths and temperatures are shown in Figure 6.…”
