1. The document discusses using a Liquid Crystal Light Valve (LCLV) as a prospective substitute for deformable mirrors in adaptive optics to enable higher order wavefront corrections. 2. It proposes using a Moire and Fourier transformation concept to convert phase variations in a wavefront into intensity variations that can be read by the LCLV. This would involve superimposing the distorted wavefront with a reference wavefront behind a spatial grid. 3. A diagram is provided and updated to show how the LCLV would fit into an adaptive optics test bench setup, including components like a sky simulator, telescope simulator, laser guide star, and science instrument.
