Abstract
A monochrome CCD camera is used in a reflectometer in order to measure the luminance of light reflected by a specimen. This application requires a radiometric calibration of the camera. We use a self-built integrating sphere with an inner diameter of 500mm as a uniform light source in order to characterize the optical system in terms of image nonuniformities introduced by the optics and the fixed pattern noise of the image sensor. We provide an image formation model and propose a new approach for pixelwise compensation of the non-uniformities.
