The sensor must reside on a stable platform removed from the target or surface being observed. Platforms for remote sensors may be situated on the ground, on an aircraft or balloon (or some other platform within the Earth's atmosphere), or on a spacecraft or satellite outside of the Earth's atmosphere. Ans: Pushbroom scanner (along-track scanner) is a type of scanning system in which detector scans the terrain of earth in the flight direction directly beneath the platform. Because the scanning of infrared radiation (a principal application) is conducted often by the articulation of mirrors or prisms, and multispectral scanning also adapts well to the use of reflective devices, almost all of the mechanisms discussed above are candidates for remote sensing. The figure below (from Jensen, 2007, Remote Sensing of the Environment) shows six types of remote sensing systems, comparing and contrasting those using scanning mirrors, linear pushbroom arrays, linear whiskbroom areas, and frame area arrays. The digital frame area array is analogous to the single vertical aerial photograph. Many electronic (as opposed to photographic) remote sensors acquire data using scanning systems, which employ a sensor with a narrow field of view (i.e.

The laser scanning system applies the laser triangulation technique to measure the 3-D height field of the fabric surface and to identify pills or fuzzes through the variation of its height; or a 2-D CCD/CMOS imaging system can be used to digitalize the reflectance properties under a certain illumination by using the intensity of image pixels, and some algorithms are then developed to characterize the pills or fuzzes to distinguish them from the common texture. A whisk broom or spotlight sensor, also known as an across-track scanner, is a technology for obtaining satellite images with optical cameras. It is used for passive remote sensing from space. In a whisk broom sensor, a mirror scans across the satellite ’s path ( ground track ), reflecting light into a single detector which collects data one pixel at a time. 2017-06-07 · In remote sensing, typical applications include the visible light (380–780 nm), infrared (780 nm–0.1 mm), and microwave (0.1 mm–1 m) ranges. This paper treats the terahertz (0.1–1 mm) range as an independent spectral band separate from microwaves.
•The disadvantages are low coverage area and high cost per unit area of ground coverage. •It is not cost-effective to map a large area using an airborne remote sensing system.

This paper treats the terahertz (0.1–1 mm) range as an independent spectral band separate from microwaves. Remote sensing sensors interact with objects remotely. Active Remote Sensing Systems Print The remote sensing systems you've studied so far are sensitive to the visible, near-infrared, and thermal infrared bands of the electromagnetic spectrum, wavelengths at which the magnitude of solar radiation is greatest. Remote sensing makes it possible to collect data of dangerous or inaccessible areas.
