IMPROVED HARTMANN-SHACK WAVEFRONT SENSOR APPARATUS AND METHOD

机译:改进的哈特曼-休克波前传感器装置和方法

摘要

An apparatus, system, and method related to improving the wavefront aberration measurement of an optical system such as an eye made with a Hartmann-Shack aberrometer relies on selectively obscuring the transmission of wavefront light propagating to or from individual lenslets of the microlens array of the aberrometer to be imaged onto a detector. A LCD is disclosed as a preferable light transmission generator/modulator. Obscuration patterns can be controlled spatially, temporally, or in combination. An improved image forming component of the aberrometer is disclosed, as well as an improved aberrometer, method of measuring, and a system for making a corrective optical surface.
