Description
Summary:We present new calibration tools dedicated to the last generation of Fourier optics viewing angle instruments developed at ELDIM. These instruments are capable to measure luminance and color at any azimuth and quasi all the incidence angles up to ±88°. Accurate measurements at grazing angles are extremely difficult to realize by any technique just because of geometrical questions. The paper presents the procedure developed to calibrate the angles and the optical axis of the instrument, and its capacity to measure accurately the luminance and color in such a large angular aperture.
