Abstract

An optical detector includes a first set of one or more photodiodes configured to generate a first photocurrent according to a first spectral response function of an incident light, a second set of one or more photodiodes configured to generate a second photocurrent according to a second spectral response function of the incident light, and a third set of one or more photodiodes configured to generate a third photocurrent according to a third spectral response function of the incident light. The optical detector further includes a module configured to output an indication of the intensity of the incident light according to a fourth spectral response function based on each of the first photocurrent, the second photocurrent, and the third photocurrent.
