A non-power-driven photometer is provided, the photometer comprising: a body; and multiple narrow angle photoreceivers (narrow angle probes) formed in the body, wherein the multiple narrow angle probes receive light in the atmosphere, which is incident over a range of different azimuth angles, and allow the characteristics of the atmosphere to be analyzed with reference to the relationship between the received light and the azimuth angle of the narrow angle probe corresponding to the received light. According to the present invention, since the photometer is driven without being supplied with power, light intensity measurement can be performed in a short time. Further, since light intensity measurement can be performed with no movement or only a short-distance movement of a vehicle or airplane equipped with the photometer, the problem of errors caused by differences in the time and location of measurement can be prevented.

The light detection substrate has a light-receiving surface for receiving light transmitted through the interference filter unit and detects the light incident on the light-receiving surface. The separator extends from the cavity layer to at least one of the first and second mirror layers and optically separates the interference filter unit as seen in a predetermined direction intersecting the light-receiving surface.

A device for improving the removal of stray light interference in a spectrometer using an aperture slit with a predefined grid pattern incorporated into it and a mounting assembly for proper alignment to the spectrometer's 2D detector to create periodic shadowing allowing the identification of the desired signal and removal of stray light is disclosed.

A light radiating portion radiates light with wavelength λ1 having predetermined absorptivity for an object and light with wavelength λ2 having smaller absorptivity for the object than the wavelength λ1, to a target, so as to scan in 2-dimensional directions. A light receiving portion receives scattered lights reflected by the target based on light with wavelength λ1 and light with wavelength λ2. A measuring portion generates information used for detection of the object at the target, based on difference between the two scattered lights with wavelength λ1 and wavelength λ2 received by the light receiving portion. An output portion outputs whether or not the object is present at the target, by 2-dimensional area information, based on scanning by the light radiating portion and information generated by the measuring portion.
