摘要： The present invention discloses an optical sensing device with multiple photodiode elements and multi-cavity Fabry-Perot ambient light filter structure to detect and convert light signal with different wavelength spectrum into electrical signal. In embodiment, the optical sensing device capable of sensing color information of ambient light or sunlight and provides blocking of infrared (IR) light within the wavelength ranging from 700 nm to 1100 nm. Preferably, the optical sensing device senses not just the ambient light brightness but also the fundamental red, green and blue color components of the ambient light.
