How to use reflectance in a … Web22 de mar. de 2024 · Multispectral cameras work by imaging different wavelengths of light. Professional multispectral cameras have multiple imagers, each with a special optical filter that allows only a precise set of light wavelengths to be captured by that imager. The output of the camera is a set of images for that particular wavelength.

WebSurface Emissivity vs Reflectivity. Opaque (non-transparent) surfaces produce a combination of emitted and reflected radiation. Because the reflected radiation isn’t related to the surface temperature, we must tell the imager to disregard that portion of what it sees. To do that we correct for emissivity (E). Reflection (R) equals 1 minus E. Web13 de abr. de 2024 · Digitising Objects. The use of digital technologies has opened up access to the primary sources that are fundamental to humanities scholars.
