High Space -Bandwidth Wavefront Sensing by Sampling and Spatial Multiplexing
Abstract
dc:descriptionThe SFS is a breakthrough concept in wavefront sensor design. It is, to our knowledge, the first high-accuracy, high-resolution, vibration-insensitive, one-shot wavefront sensor. It achieves high accuracy by using a phase-shift shearing interferometric approach in detecting wavefront phase differences. It achieves high resolution by sampling the input wavefront and fanning out the samples to the output plane (space multiplexing), on a common optical path. The common path fan-out configuration makes the system compact and vibration-insensitive.
