Modulation transferfunctionformula

RP Optical Lab offer a variety of high performance Fix, discrete and continuous zoom thermal lenses covering the entire range of SWIR, MWIR, LWIR.

Abstract  We have constructed an analytic formula for the mean radial modulation transfer function of the best-corrected human eye as a function of pupil diameter, based on previously collected wave front aberrations from 200 eyes (Thibos, Hong, Bradley, & Cheng, 2002). This formula will be useful in modeling the early stages of human vision.
