Abstract

A method for measuring the amount of direct solar radiation and an apparatus according to the method. The invention provides a light sensor which rotates at a constant speed while scanning the sky including the sun. The differential coefficient of the radiation received is obtained from the output of the light-receiving element, thus substantially eliminating the scattered light component from the output. The preferred embodiment of the light-receiving element is a pyroelectric detector.
