摘要:
An optical device includes a substrate. a non-planar transparent structure on a first surface of the substrate, the non-planar transparent structure being made of a first material, and a molded refractive surface on the first surface of the substrate adjacent the non-planar transparent structure, the molded refractive surface being made of a second material, different from the first material.
摘要:
An optical system (302) has a plurality of optical surfaces (304, 305, 306, 307, 308, 309) configured to provide blurred images of objects located within a selected range of object distances. At least two of the plurality of optical surfaces are configured to contribute to the blurring. An imaging system (300) includes a blurring optical system (302), a sensor (310) which receives light directed through the optical system, and an image processor (320) which selects one or more deblurring functions and applies the deblurring functions to provide a processed image. The processor may apply different deblurring functions to different sets of the raw data representing different portions of the field of view.
摘要:
Provided are methods and systems for identification and analysis of materials and molecular structures. An apparatus for identification and analysis of materials and molecular structures may include a laser. The laser may, in turn, include an amplified spontaneous emission-suppressed single-frequency laser excitation source. The apparatus may further comprise a plurality of filters. The plurality of filters may include reflective volume holographic grating blocking filters. The apparatus may also comprise an optical unit and an optical spectrometer. The optical unit may be configured to deliver excitation energy to a sample substance and capture Raman signal scattering from the sample substance. The optical spectrometer may be disposed in a path of the Raman signal and configured to measure a spectrum of the Raman signal and generate a detection signal. Finally, the apparatus may comprise a processing unit configured to analyze the spectrum.
