Andor sCMOS Cameras for Adaptive Optics Wavefront Sensing
WebbUnderstanding Wavefronts. Adaptive optics (AO) is a technology used to enhance the performance of an optical system by manipulating the optical wavefront. This improves the final output, improving performance compared to a non-adaptive system. A wavefront is defined as a surface associated with a propagating wave passing through all points that ... Webb16 dec. 2011 · The wavefront sensor here used 16 × 16 pixels per sub-aperture. This bias is due to the pixellated and truncated nature of a Shack–Hartmann sensor. In our simulations, detectors are modelled with a uniform response, and so a flat-field image of unity is used. goldilocks and the three bears cbeebies
