Abstract
The disclosure relates to a photodetector system including a multi-junction detector having a first junction configured to generate a first current when irradiated with a first optical radiation component within a first spectral range, and at least a second junction configured to generate a second current when irradiated with a second optical radiation component within a second spectral range that is different than the first spectral range. The photodetector system also comprises a microprocessor adapted to generate a first indication related to a first characteristic of the first optical radiation component based on the first current, and generate a second indication related to a second characteristic of the second optical radiation component based on the second current.
