SPID, a high spectral resolution diffraction limited camera

摘要

SPID aims at offering a high spectral resolution in both short-exposure (speckle imaging) and long-exposure (adaptive optics with partial compensation) modes. It offers an adjustable spectral resolution (from 60 up to 3000) in the range 400-750 nm. For differential observation of astronomicla objects. SPID gives images in tow spectral bandwidths at the same time. The width and the central wavelenght of each bandwidth can be chosen independently. A high image quality is achieved thanks to a new design derived from a Courtes monochromator. SPID also includes a wavefront sensor for post-compensation processing.
