Latest Patents

Sijiong Zhang holds a patent for a "Phase-diversity wavefront sensor." This measuring apparatus provides data relating to the shape of an input radiation wavefront, which is describable at a pre-determined location in an optical system. The apparatus includes an aberration device that introduces an aberration to the input radiation wavefront. The shape of this aberration is defined by a complex-valued filter function with non-mixed symmetry. Additionally, the device features a detector with a radiation-sensitive surface capable of detecting the intensity of incident radiation. The detector is coupled to an output device that measures the intensity of the incident radiation. The aberration device acts on the input wavefront shape to produce first and second output radiation signals, which are detected by the detector. In combination, these signals enable the output device to provide data indicating the extent to which the wavefront shape is non-planar.
