Abstract
Methods, devices and systems are disclosed that enable accurate and reliable measurements of wavefront aberrations with a wide dynamic range. The described wavefront sensors can be implemented at a low cost and without any moving parts. One wavefront sensor includes an optical pyramid positioned to receive a focused incoming light beam. The optical pyramid includes three facets that each allow a portion of the focused incoming light beam to exit the optical pyramid. The wavefront sensor also includes one or more imaging lenses positioned to receive light that exits each of the facets of the optical pyramid, and one or more lenslet arrays positioned to receive light from the one or more imaging lenses and to produce a plurality of focused light spots corresponding to each lenslet of the lenslet array.
