Image spectrometer
WitrynaThe term spectrophotometer can refer to quite a variety of instruments that measure light, with the exact definition depending on the area of science or industry. In all cases the term ‘photo’ is used to indicate that the spectrometer is for the quantitative measurement of light intensity with wavelength. WitrynaThe prism-grating-prism spectrograph had a nominal spectral range of 430–900 nm with a 6.6-mm axis, and attached to the camera for generating line-scan images. The spectrograph had a nominal spectral resolution of 2.5 nm, and was connected to a 2/3-inch silicon-based CCD sensor with 1280 × 1024 pixel resolution.

Witryna1 kwi 2024 · The image mapper is an array of long strip mirrors arranged with 2D tilt angles as shown in Fig. 2. The fore optics is telecentric in the image space, so the imaging principle rays are parallel to the optical axis. In the imaging spectrometer, the reflected light from each mirror is collimated by the lens L2 and dispersed by a … Witryna10 kwi 2024 · In this paper, a temporally and spatially modulated long-wave infrared (LWIR)-imaging Fourier transform spectrometer was used to realize hyperspectral imaging. The spectral range was 700~1450 cm−1 (7~14.5 μm). The frame rate of infrared imaging was 200 Hz. The muzzle-flash area of guns with calibers of 5.56 …

This paper gives a review of imaging spectrometry and addresses the following topics: airborne and spaceborne systems available, spectral and geometric data pre-processing, atmospheric …
WitrynaSpectrometers for Imaging Applications. Dispersive spectrometers image spectra; that is their function. Imaging the spectrum is required to resolve discrete wavelengths. … WitrynaOptical spectrometers are the most common type of spectrometer. They take light, separate it by wavelength and create a spectra which shows the relative intensity of these separate wavelengths. This basic principle has a wide range of applications and uses. Broadly speaking, all optical spectrometers consist of an entrance slit, a …
