Abstract: Plural electronic or optical images are provided in a streak optical system, as for instance by use of plural slits instead of the conventional single slit, to obtain a third, fourth etc. dimension—rather than only the conventional two, namely range or time and azimuth. Such additional dimension or dimensions are thereby incorporated into the optical information that is to be streaked and thereby time resolved. The added dimensions may take any of an extremely broad range of forms, including wavelength, polarization state, or one or more spatial dimensions—or indeed virtually any optical parameter that can be impressed upon a probe beam. Resulting capabilities remarkably include several new forms of lidar spectroscopy, fluorescence analysis, polarimetry, spectropolarimetry, and combinations of these.

Abstract: In detection and sensing, light is transmitted through layers or structures that vary laterally, such as with a constant gradient or a step-like gradient. After transmission, a position of a transmitted portion of the light or of output photons can be used to determine wavelength change or to obtain other photon energy information. The light can be received, for example, from a stimulus-wavelength converter such as an optical fiber sensor or another optical sensor. A component that propagates the light from the converter to a transmission structure can spread the light across the transmission structure's entry surface. At the exit surface of the transmission structure, photosensor components can sense or detect transmitted light or output photons, such as with a photosensor array or a position sensor. A photosensed quantity can be compared, such as with another photosensed quantity or with a calibration quantity. A differential quantity can be obtained using photosensed quantities.

Abstract: A spectrophotometer, for online non-destructive optical examination of fruit or vegetables or the like avoids saturation of the data level, or the data level being too small, due to changes in rate of feeding or variation in the fruit or vegetables. Light that has passed through the fruit or other article is divided into different spectral components and received at two locations, a main light reception unit and a sample-use light reception unit. A digital value obtained from the sample-use light reception unit is compared with a predetermined reference value, Based on this comparison, the gain of a variable gain amplification circuit is set to an optimum value. The signal from the main light reception unit is passed through the variable gain amplification circuit, a zero-point correction circuit, and an A/D converter, to obtain digital data to be read for obtaining suitable wavelength characteristic data.

Abstract: In a method and apparatus for detecting optical spectra, two or more partial beams are generated from an incident beam, each of said partial beams being assigned to a different spectral region. The partial beams travel through a spectrometer lens system and are detected in a spatially separated manner. For this purposes, the partial beams generated from the incident beam are directed to respective spatially separated diffraction gratings that are virtually superimposed in the beam path, and are assigned to different spectral regions. After passing through the diffraction gratings, the spectrally separated partial beams are combined to a joint beam path traveling through the spectrometer lens system. Preferably, the partial beams comprising the different spectral regions can be spectrally separated after passing through the spectrometer lens system and can be detected in spatially separated detectors assigned to the different spectral regions.
