    Abstract: A Raman spectrometer optically separates an optical signal scattered by a sample from an incident excitation light beam into an unshifted return component at a first wavelength and one or more Raman scattered components at shifted wavelengths characteristic of the sample. The unshifted return component—but not the Raman scattered components—is attenuated prior to impinging on an optical detector. The unshifted return then serves as the basis for real-time calibration to account for fluctuations in optical intensity, wavelength shift, and/or spectral peak width, based on a comparison of the unshifted return peak to a reference standard for stable reflectance.

    Abstract: An apparatus and method for laser probing of a DUT is disclosed. The system enables laser voltage imaging state mapping of devices within the DUT. A selected area of the DUT is illuminating a while the DUT is receiving test signals causing certain of the active devices to modulate. Light reflected from the DUT is collected and is converted into an electrical signal. Phase information is extracting from the electrical signal and a two-dimensional image is generated from the phase information, wherein the two-dimensional image spatially correlates to the selected area.

    Abstract: Systems and methods for performing optical spectroscopy using a self-calibrating fiber optic probe are disclosed. One self-calibrating fiber optic probe includes a sensing channel for transmitting illumination light to a specimen and for collecting spectral data of the specimen. The spectral data includes the illumination light diffusely reflected from the specimen at one or more wavelengths. The self-calibrating fiber optic probe may also include a calibration channel for transmitting calibration light. The calibration light and the illumination light are generated simultaneously from a common light source. The calibration channel collects calibration spectral data associated with the calibration light contemporaneously with the collection of the spectral data of the specimen.

    Abstract: A mobile computing device that includes an image sensor may be used to detect the result of a biomolecular assay. The biomolecular assay may be performed in an optical assay medium that provides an optical output in response to light from a light source, with the optical output indicating result. A wavelength-dispersive element may be used to disperse the optical output into spatially-separated wavelength components. The mobile computing device may be positioned relative to the wavelength-dispersive element such that different wavelength components are received at different locations on the image sensor. With the mobile computing device positioned in this way, the image sensor may be used to obtain one or more images that include the separated wavelength components of the optical output. A wavelength spectrum of the optical output may be determined from the one or more images, and the result may be determined from the wavelength spectrum.
