Abstract:
A system and method are disclosed for standoff spectroscopy of molecules (e.g. from a residue) on a surface from a distance. A source emits radiation that modifies or conditions the residue, such as through photodecomposition. A spectral generating source measures a spectrum of the residue before and after the residue is exposed to the radiation from that source. The two spectra are compared to produce a distinct identification of the residues on the surface or identify certain properties of the residue.
Abstract:
A sensor array comprises a first blue sensor and a second blue sensor; and a first green sensor and a second green sensor, wherein the blue sensors have a filter that only passes blue light, and the green sensors have a filter that only passes green light.
Abstract:

Abstract:
A device for measuring the shading of a translucent pane having an exterior side and an interior side comprising first and second photoelectric sensors for measuring unattenuated daylight, each of the sensors having a photosensitive surface and a spectral sensitivity substantially corresponding to the spectral sensitivity of the human eye and generating an output signal proportional to the intensity of the measured daylight, a first mounting element for mounting the first sensor on the exterior surface with the photosensitive surface of the first sensor facing away from the exterior surface, a second mounting element for mounting the second sensor on the interior surface with the photosensitive surface of the second sensor facing the interior surface, a housing, and an electronic circuit disposed in the housing and electrically connected to the first and second sensors for calculating the difference of the output signals of the first and second sensors, calculating the ratio of the difference to the signal from the first sensor, and displaying the ratio as a reference value.
Abstract:
A fluorescence radiation detector of the Fraunhofer line discriminator type. A sky telescope and an earth telescope each form radiation beams which are directed to a single optical chopper. The chopper sequentially directs each beam through a single Fabry-Perot filter centered at the Fraunhofer line and a single neutral density filter. The chopped segments are recombined to form a beam containing A, B, C, and D portions in time sequence where: A the direct solar intensity within the continuum; B the direct solar intensity inside the selected Fraunhofer line; C the reflected solar intensity inside the selected Fraunhofer line; and D the reflected solar intensity in the continuum. A single photomultiplier tube with a blocking filter in front receives the beam and produces corresponding sequential electrical pulses which are electronically processed to yield fluorescence (p) from the equation
Abstract:
The present disclosure relates to an inspection apparatus, a sensing apparatus, a sensitivity control apparatus, an inspection method, and a program that perform inspection with improved accuracy. The inspection apparatus includes a detection section for detecting a plurality of different wavelength region components of ambient light reflected from an inspection target to be inspected, and a control section for controlling the sensitivity of each of the different wavelength region components. The control section controls the sensitivity by calculating a histogram indicating the detection level in every wavelength region of light reflected from the inspection target that is detected by the detection section, and determining, based on histograms of particular spectroscopic components, whether or not the sensitivity is properly set for the detection section. The present technology is applicable, for example, to an inspection apparatus that inspects vegetation.
Abstract:
A food product analysis device (1) includes a memory portion that stores food product database containing a plurality of items of food product information including characteristic information including at least one of first light absorption information which is information relating to absorption of near infrared light and ingredient information which is information relating to an ingredient of a food product, and type information which is information relating to a type of the food product. In addition, the food product analysis device includes an analysis portion that matches measured information, which is the characteristic information obtained on the basis of a result of measurement using the near infrared light, with the food product database.
