    摘要： An apparatus is disclosed wherein laser radiation illuminates a sample using all reflective optics and wherein in-elastically scattered light from the sample is collected using the identical elements. The apparatus obviates the problem of contaminating the laser radiation with unwanted spectra from transmissive optics while providing very high rejection of the laser radiation with respect to the in-elastically scattered light. In addition, the apparatus can collect and launch light with high numerical aperture and large field of view.

    摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for detecting proximity and/or color of an object. In one aspect, an optical sensor includes a plurality of transmissive interferometric elements, a plurality of detectors positioned to detect the presence and/or intensity of light transmitted through the elements, and a processor to determine the proximity of an object based at least in part upon input from the detectors. An optical signal can be sensed by selectively actuating certain elements in a set of transmissive interferometric elements in an array to allow transmission of optical signals within a first spectrum through the array, and detecting optical signals transmitted through the array.

    摘要： A radiometer for detecting and measuring components of luminescence and reflected light contained in a light beam from a target which included means for sensing the temperature of an optical filter in the radiometer and for adjusting the angular position of the mount which carries the filter in response to the sensed temperature to thereby retune the filter to its center frequency when changes in temperature occur. Longitudinal movement of an adjustment rod changes the angular position of the mount. A micrometer means manually moves the rod in one embodiment while a motor moves the rod in a second embodiment. The rod carries a means for sensing the longitudinal position of the rod (hence the rotational position of the mount) and generates a signal representative thereof. A means on the mount senses the temperature of the filter and generates a signal representative thereof. The temperature and position signals are compared by a processing circuitry which outputs an error signal if the position of the mount does not match a predetermined temperature signal. This error signal the (1) directly operates a control mechanism to move the adjustment rod which rotates the mount to a new angular position to retune the center frequency of the filter or (2) is fed to a visual indicator, which is brought back to a desired reference point by rotating the micrometer.

    摘要： Provided is a monochromatization device for easily selecting light having a specific wavelength, comprising: a first broadband filter arranged to have a first rotational angle with respect to an incident direction of light to enable a first wavelength band to pass therethrough with respect to the incident light; a second broadband filter arranged to have a second rotational angle with respect to an incident direction of light to enable a second wavelength band to pass therethrough with respect to the light passing through the first broadband filter; and a path compensation unit for adjusting a light path so that the light path passing through the second broadband filter is the same as a path of the light incident to the first broadband filter. Accordingly, the output light efficiency for the incident light is increased and the required specific wavelength can be more easily selected.

    摘要： The invention relates to methods and systems for measuring and/or monitoring the chemical composition of a sample (e.g., a process stream), and/or detecting specific substances or compounds in a sample, using light spectroscopy such as absorption, emission and fluorescence spectroscopy. In certain embodiments, the invention relates to spectrometers with rotating narrow-band interference optical filter(s) to measure light intensity as a function of wavelength. More specifically, in certain embodiments, the invention relates to a spectrometer system with a rotatable filter assembly with a position detector rigidly attached thereto, and, in certain embodiments, the further use of various oversampling methods and techniques described herein, made particularly useful in conjunction with the rotatable filter assembly. In preferred embodiments, the rotatable filter is tilted with respect to the rotation axis, thereby providing surprisingly improved measurement stability and significantly improved control of the wavelength coverage of the filter spectrometer.
