摘要： A display apparatus includes a display screen, and a controller that causes the display screen to display a composite image in which a first image acquired by imaging a space by a camera and a second image representing at least one type of aerosol existing in the space are combined. The position of the at least one type of aerosol as seen in a depth direction in the first image is reflected in the second image.

摘要： A light observation apparatus includes: a first photodetector that, upon irradiation of at least part of a physical object with irradiation light, receives first light containing ambient light and at least one selected from the group consisting of reflected light returning from the at least part and fluorescence produced from the at least part, and that outputs a first output signal representing a reception intensity of the first light; a second photodetector that receives second light containing the ambient light and outputs a second output signal representing a reception intensity of the second light; and a signal processing circuit. The signal processing circuit attenuates a first signal component corresponding to the ambient light from the first output signal based on the first output signal and the second output signal.

摘要： A measurement apparatus includes a light source, an interferometer, a light receiver, and a signal processor. The light source emits laser light to a scatterer in the atmosphere. The laser light has multiple oscillation frequencies separated from each other at equal frequency intervals. The interferometer produces interference in scattered light generated as a result of the laser light being scattered by the scatterer. The light receiver receives Mie scattered light included in the scattered light subjected to the interference produced by the interferometer and generates a signal. The signal processor detects the quantity of the Mie scattered light based on the signal. Each of the equal frequency intervals is smaller than the full width at half maximum of the peak of a frequency spectrum of Rayleigh scattered light. The Rayleigh scattered light is generated as a result of the laser light being scattered by molecules forming the atmosphere.
