摘要： A light sensor that generates a first output signal indicative of an intensity of light received from a predetermined direction in a first band of wavelengths is disclosed. The light sensor includes a substrate having first and second photodetectors, a first filter layer, and a controller. The photodetectors are sensitive to light in the infrared portion of the optical spectrum as well as to light in the first band of wavelengths, and generate first and second photodetector signals. The first filter layer transmits light in the first band of wavelengths and light in the infrared portion of the optical spectrum while blocking light in a portion of the visible spectrum outside of the first band of wavelengths, without altering light received by the first photodetector. The controller processes the first and second photodetector signals to produce the first output signal that is corrected for infrared in the input light.

摘要： A photodetector and method for making the same is disclosed. The photodetector includes a substrate having first, second, and third photodiodes and first and second pigment filter layers. The first, second, and third photodiodes generate first, second, and third photodiode output signals, respectively, each photodiode output signal being indicative of a light intensity incident on that photodiode and a dark current that is independent of the light intensity. The first and second pigment filter layers overlie the first and second photodiodes while a layer having both the first and second pigment filter layers overlie the third photodiode. An output circuit combines the first and third photodiode output signals to provide a first corrected output signal and combines the second and third photodiode output signals to provide a second corrected output signal.
