Temperature-stable incoherent light source

摘要: Embodiments generally relate to a light source and methods for minimizing temperature sensitivity of source. In one embodiment includes light-emitting diode, beam having an optical axis, photodetector polarizer. The diode is operatively configured emit the beam. splitter, positioned intercept beam, first surface reflect portion transmit second therethrough. capture after reflection by splitter generate photocurrent proportional intensity that captured portion. polarizer between polarize along polarization direction perpendicular its axis.
