Abstract:
A laser-based spectroscopy system that combines a distance/proximity standoff sensor, a high-repetition rate laser spectroscopy system, and software with a decision-making algorithm embedded in a processing unit which in combination performs selective firing of the laser when the target object is within an interrogation zone. In a related embodiment, the system provides selective sorting of spectroscopic signals based on information from the standoff signal and from information contained in the spectral signals themselves. The laser emission can be actively controlled while keeping the laser firing, thereby preserving the thermal stability and hence the power of the laser; and the standoff sensor information and the spectral information can be combined to determine the proper relative weighting or importance of each piece of spectral information.

Abstract:
A measurement system capable of accurately aligning the corresponding measurement points of a plurality of measurement targets to evaluate the measurement targets from measurement results at both measurement points is provided. A measurement system (100) includes a measuring instrument (10) and a PC (20), and the measuring instrument (10) includes a spectroscopic unit (12) that measures a measurement point of a measurement target and a camera (16) that images surroundings of the measurement point in real-time. The PC (20) displays an evaluation image of continuous image information of an evaluation medium, which is imaged and displayed by the camera (16) of the measuring instrument (10) on a display screen of a display unit (22) so as to be superimposed on a reference image of still image information of a reference medium, which has been imaged by the camera (16) and stored in a memory (24). By comparing the measurement data obtained by measuring the measurement point in the evaluation image when both images overlap each other substantially exactly and the measurement data of the measurement point in the reference image stored in the memory (24), it is possible to perform positioning easily and compare the measurement data.
Abstract:
A spectral colorimetric apparatus includes a housing which includes a side wall. An outer surface of the side wall is an adjustment surface capable of adjusting a position of a light receiving member by moving in a state in which the light receiving member abuts on the adjustment surface. The light receiving member is supported by the side wall of the housing in a state in which the light receiving member abuts on the adjustment surface and receives a light beam that is dispersed by a concave surface reflection type diffraction element and passes through an opening portion. The adjustment surface is parallel to a tangential line at a part of a Rowland circle of the concave surface reflection type diffraction element, through which a light beam received by the light receiving member passes.
