WebMar 15, 2024 · The prototype large-dynamic-range Shack-Hartmann wavefront sensor presented uses a translatable plate with subapertures placed in conjugate with the lenslet array to increase the dynamic range by a factor of two with no subsequent change in measurement sensitivity and sampling resolution of the aberration. Expand WebMar 10, 2024 · An imaging system’s dynamic range determines the darkest and brightest signals that it can detect [ 7 ]. When the dynamic range of an imaging system cannot cover the intra-scene dynamic range (IDR) of samples, a trade-off must be made between the loss of weak signal and intense signal saturation. It becomes even more challenging for SIM …
