1. A method, comprising:
reverse biasing a first pixel in a pixel array;
forward biasing a second pixel in the pixel array, wherein the first and second pixels are photosensitive, wherein the first and second pixels have a common cathode;
measuring a voltage for the second pixel; and
determining a temperature of the pixel array from the measured voltage for the second pixel,
wherein the first and second pixels are coupled to a reverse bias voltage source at the common cathode, and wherein the second pixel, and not the first pixel, is coupled to a forward bias voltage source that has a higher voltage than the reverse bias voltage source to forward bias the second pixel.
