Title: WAVEFRONT ABERRATION AND DISTANCE MEASUREMENT PHASE CAMERA
Abstract:
A system consisting of a phase camera with microlenses placed in the focal point of a converging lens, wherein the camera data is processed using a combined Fourier 'Slice' and Fast Fourier Transform edge detection technique providing both a three-dimensional wavefront map and a real scene depth map within a broad range of volumes. the invention is suitable for use in any field where wavefronts need to be determined, such as earth-based astronomical observation, ophthalmology, etc., as well as in fields requiring metrology, e.g. real scenes, CCD polishing, automobile mechanics, etc. The invention is particularly suitable for atmospheric tomography using ELTs (large-diameter telescopes: 50 or 100 metres).
