The development of a prototype ambient light sensor for use in the runway visual range system / by Brian Sheppard = Développement du prototype d'un détecteur de la lumière ambiante pour le système de mesure...: En57-58/820-1975E-PDF

"This technical memorandum describes the development of a prototype ambient light sensor for use in the runway visual range (RVR) system. We review the definition and the computation of RVR. We compare the values of the ambient light related RVR parameters used in Canada with those used by other nations. The advantage of a continuous or multi-level ambient light measurement is considered. The results of laboratory and field tests of photovoltaic cells and photoresistors are compared with the basic sensor performance requirements for such continuous or multi-level light measurements. A circuit using a photoresistor as detector was constructed, calibrated and installed for evaluation at Toronto International Airport"--Abstract.
