Sažetak
A light source includes a semiconductor light emitter having an electrical drive input and operatively configured to emit a light beam ; a first weakly polarizing beam splitter positioned to capture the light beam, reflecting one portion, and transmitting another portion with an output intensity P. The light source includes a second polarizing beam splitter positioned to capture the reflected portion of the light beam and split it into first and second detector light beams of orthogonal polarizations. The light source further includes first and second detectors capturing those detector light beams, and is configured to deliver corresponding first and second output signals from corresponding detector outputs. The light source includes an electronic circuit coupled to those electrical outputs and to the electrical drive input of the light emitter.
