METHODS OF RADIOMETRIC CALIBRATION [PDF]
, 1962 Abstract : A general treatment of the calibration of optical instruments is presented which are to be used to measure electromagnetic radiation from sources of interest to the military services. The infrared spectral region is emphasized although the ultraviolet and visible wavelengths ar also treated.

Radiometric calibration of a Helmholtz stereo rig [PDF]
Proceedings of the 2004 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2004. CVPR 2004., 2004 Helmholtz stereopsis guarantees unbiasedness by BRDF of the search for inter-image correspondences. In a practical setup, calibrated pixel sensitivity and corrected light anisotropy are required for the method to work well. In this paper a simple method for joint light-camera radiometric calibration is proposed.

The Radiometric Measurement Quantity for SAR Images
, 2013 A Synthetic Aperture Radar (SAR) system measures among other quantities the terrain radar reflectivity. After image calibration, the pixel intensities are commonly expressed in terms of radar cross sections (for point targets) or as backscatter ...
