For accurate measuring of the absolute spectral brightness of light sources it is necessary to perform spectral calibration of spectrometers and radiometers on known standards. Periodic verification (calibration) of devices should be carried out at least once a year during utilization of the device by user and after repair.
Results of geometrical calibration are used in aerial mosaic composing for subsequent construction of terrain models, orthophoto, determination of geometric characteristics of objects on images, as well as for the correction of distortion on the photo.
We offer our services in radiometric and photogrammetric calibration of spectrometers, radiometers, pyrometers, temperature control units and sources of radiation.
