Optical sensor for illumination mixtures and method for the design thereof |
摘要 |
An optical sensor system is provided which provides portions of the intensity spectrum of various types of natural and artificial light and combinations thereof. The illumination passes through a series of band pass filters or through a diffraction grating to be sensed by a plurality of photosensors sensing different portions of the spectrum. The photosensors are connected to a processing system which can determine the nature of the illuminants from characteristic areas of the intensity spectrum falling on the photosensors.
