The present disclosure relates to a device and method for accurately measuring an azimuth angle and an elevation angle of mid-infrared laser light. The device includes a laser, an atomic gas cell, a filter, a displacement platform, and a beam mass spectrometer. Pump light generated by the laser enters the atomic gas cell along an optical axis which is a Z-axis for a spontaneous frequency conversion process, and a generated reference beam enters the beam mass spectrometer through the filter; target mid-infrared laser light and the pump light intersect in the atomic gas cell to induce a second frequency conversion process, and a generated beam to be measured enters the beam mass spectrometer through the filter; and the beam mass spectrometer is arranged on the displacement platform and simultaneously detect spot images of the reference beam and the beam to be measured at different positions, respectively.

A non-contact temperature measurement device includes: a matching processing unit to estimate a correspondence relationship of pixels between images; a positional relationship estimating unit to estimate a positional relationship between an infrared camera and an object on the basis of the correspondence relationship of the pixels; a luminance correcting unit to correct luminance corresponding to a temperature in a luminance image on the basis of the positional relationship; and an emissivity correcting unit to estimate emissivity using the correspondence relationship of the pixels and the luminance image and generate a temperature image on the basis of the emissivity, in which the matching processing unit estimates the correspondence relationship of the pixels between images captured by the infrared camera in the same light receiving sensitivity wavelength band, and the emissivity correcting unit estimates emissivity using images captured by the infrared camera in different light receiving sensitivity wavelength bands.

A position locating system to locate relative position information between a marine vessel and a trailer includes a laser scanner on a first object, that is one of a marine vessel and a trailer for the marine vessel, to reciprocatingly scan a predetermined range in a horizontal direction with laser light, a laser light receiver on a second object, that is the other of the marine vessel and the trailer, to receive laser light emitted from the laser scanner, and a position locator configured or programmed to locate relative position information between the marine vessel and the trailer based on light receiving timings when the laser light emitted from the laser scanner is received by the laser light receiver.

An imaging optical system for imaging at least one light source onto a light-sensitive sensor, includes an optical aperture, a beam-forming optical element, and the light-sensitive sensor. The beam-forming optical element is a planoconcave cylindrical mirror, more particularly a planoconcave circular-cylindrical mirror.

A system for providing integrated detection and countermeasures against unmanned aerial vehicles include a detecting element, a location determining element and an interdiction element. The detecting element detects an unmanned aerial vehicle in flight in the region of, or approaching, a property, place, event or very important person. The location determining element determines the exact location of the unmanned aerial vehicle. The interdiction element can either direct the unmanned aerial vehicle away from the property, place, event or very important person in a non-destructive manner, or can cause disable the unmanned aerial vehicle in a destructive manner.
