摘要： According to a present invention embodiment, safety is enhanced for a non-eye-safe limited-range laser sensing system. The laser sensing system typically has an operating range limited to a well-defined spatial interval. A range measurement is utilized to control emissions of the non-eye-safe laser. In particular, when the range to a target is outside the designed spatial interval defining the operating range of the laser sensing system, transmission of the non-eye-safe laser beam is disabled or rendered non-hazardous. In other words, the transmission of the non-eye-safe laser beam is disabled in response to no detection of a hard target within the operating range of the laser sensing system, or when an object is detected between the laser sensing system and the spatial interval that defines the operating range. The target distance may be tracked to change the location (and possibly, width) of the adaptive spatial interval defining the operating range.

摘要： Systems and methods for operating, particularly in the field, a Raman spectroscopy device that includes a laser, a spectrograph, an intensified charge coupled device (ICCD), and an autofocus subsystem. Before spectral data acquisition commences a series of ancillary data checks is performed to monitor operating conditions of at least the laser, the ICCD, and the autofocus subsystem. Further, after each Raman spectrum acquisition, a series of data quality checks is performed to enhance confidence in the just collected data. Only spectral data that passes the data quality checks are further processed. However, all spectral data are stored in a log file. When the log file reaches a predetermined capacity, the log file is closed, and a new round of ancillary data checks is performed to again monitor the status of the Raman spectroscopy device.

摘要： A method is provided for calibrating a spectrometer device used for Raman scattering analysis. A predetermined dispersion curve for a diffraction grating or spectrograph of the spectrometer device is modified based on spectrum data associated with detected dispersed light from a calibration light source to produce a modified dispersion curve. The wavelength of a Raman light source on a light detection device is determined. Calibration data for the spectrometer device is computed from the Raman line peak positions for the first chemical, the wavelength on the detection device of the Raman light source and the modified dispersion curve.

摘要： A spectroscopic identification method and system are provided that uses the primary or main spectroscopic features of a source, such as those as arising from chemical functional groups, to describe and distinguish the source. These primary spectroscopic features make up a portion (i.e., are a subset) of the entire spectroscopic data for a particular source but can nevertheless be used as the basis of separating spectra from multiple source. When analyzing spectroscopic data obtained from a sample for one or more sources, the analysis first focuses on the primary spectroscopic features for a source rather than the entire spectra for a source.

摘要： Systems and methods for increasing the quantum efficiency of a photocathode used in an intensified an intensified array detector with a photocathode, such as a charge-coupled device (ICCD) are presented. A quantum efficiency enhancement device is disposed in front of an ICCD and is configured to enable or facilitate an increase in the angle of incidence of incoming rays incident on the photocathode. The ICCD itself may be tilted to achieve an increased angle of incidence, and such tilting is preferably only in a direction in which pixel columns of the ICCD extend such that a plane of incidence of incoming light to the ICCD is perpendicular to a direction of wavelength dispersion. The quantum efficiency enhancement device may include re-imaging optics, an optical tilt compensator and optical coupler.
