Abstract
The invention relates to an optical detection system for detecting the optical distribution of a display device having a light source and a predetermined display range divided into multiple virtual detection regions. The system includes a power module for supplying power to the light source, a monochromatic module for detecting luminous intensity of the light source at various wavelengths within a selected virtual detection region, multiple optical sensor modules, each corresponding to one of the virtual detection regions, a memory module saving wavelength correction parameters of the optical sensor modules, and a processor module receiving the wavelength distribution within the selected virtual detection region of the display device, and for calculating and compensating for expected detection values of the respective optical sensor modules based on the wavelength correction parameters and actual detection values of the optical sensor modules.
