Abstract
Methods and apparatus for determining the temperature of a pixel array. In embodiments, a first pixel in a pixel array is reverse-biased and a second pixel in the pixel array is forward-biased. A voltage for the second pixel can be measured to determine a temperature of the pixel array from the measured voltage for the second pixel.
