Airborne lidar sensors are used by companies in the remote sensing field. Imaging techniques having a strong affinity with compressive sensing include coded aperture and computational photography. Astronomical spectroscopy is a particularly significant type of remote spectral sensing. Satellite imagery is an example of passive remote sensing. Microwave Remote Sensing and Information Technology. This approach appears in the signal recovery framework called compressed sensing. Many other in situ and remote sensing systems commonly use analogous technology. Touchpads operate in one of several ways, including capacitive sensing and resistive touchscreen. Another lidar technique for atmospheric remote sensing has emerged. Commercial shortwave-infrared cameras based upon compressed sensing are available. Spectroscopy is also used in astronomy and remote sensing on Earth. This is advantageous for applications in quantum sensing and quantum communication. Hyperspectral remote sensing of minerals is well developed. Microchip Technology's offerings focus on lower-power operation designed for sensing or command and control products. This is the method used for remote sensing the disasters.
