Abstract

This paper focuses on the technological aspects of an integrated wavefront sensor developed in the framework of standard CMOS technology. A wavefront sensor is used in Adaptive Optics to detect wavefront aberrations, which can be compensated by a deformable mirror. We use the Hartmann method and the sensor consists basically of two components: an opaque mask with apertures and an optical detector. Our main goals are compatibility with mainstream technologies and real-time operation. We briefly report on the performance of the sensor in open- and closed- loop.
