Abstract: An optical metrology device performs multi-wavelength polarized confocal Raman spectroscopy. The optical metrology device uses a first light source to produce a first light beam with a first wavelength and a second light source to produce a second light beam with a second wavelength. A dichroic beam splitter partially reflects the first light beam and transmits the second light beam to combine the light beams along a same optical axis that is incident on a sample. The dichroic beam splitter directs the Raman response emitted from the sample in response to the first light beam and the second light beam together towards at least one spectrometer and directs the first light beam away from the at least one spectrometer. A chopper may be used to isolate the Raman response to the first and second light beams that is received and spectrally measured by the at least one spectrometer.

Abstract: The present disclosure provides an apparatus and method for wavefront reconstruction based on rotationally symmetric extended structured light illumination. The apparatus includes a laser device, a neutral density filter, a microscope objective, a pinhole, a collimating lens, a beam splitter prism, a spatial light modulator, a lens to be measured, and an image acquisition device that are sequentially arranged. The method permits modulation of incident parallel light into phase grating-like structured light by using a spatial light modulator. Based on the characteristic of non-infinitely small pixel unit of the spatial light modulator, changing the modulation pattern of the spatial light modulator may result in different forms of structured light. Not only the object to be measured but also the real structured light wavefront can be recovered by acquiring diffraction spots at the focal plane and simultaneously updating the object plane and the structured light plane using an algorithm.
