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 …

WitrynaSpectroscopy is a branch of science concerned with the spectra of electromagnetic radiation as a function of its wavelength or frequency measured by spectrographic equipment, and other techniques, in order to obtain information concerning the structure and properties of matter. [8] Spectral measurement devices are referred to as … WitrynaImaging spectrometers allow to depict these narrow features and thus map surface mineralogy based on spectral image characterization. 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 …
WitrynaSpectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the … WitrynaIt is an image spectrometer and was contributed by Italy. To jest spektrometr obrazu i został przeznaczony przez Włochy. Often, a spectrometer is used to give quantitative values for color strength. Często, spektrometr jest użyty by wskazywać iloczasowe wartości dla siły koloru. This simple scheme in fact describes how some …
