Claim Text:
1. An optical device, comprising: a plurality of light sources, each of the plurality of light sources to provide a light beam; at least one beam combiner to combine the light beams from the plurality of light sources to provide a combined light beam; a beam splitter comprising a first surface and a second surface, the beam splitter to receive the combined light beam and to split the combined light beam into a primary light beam and a secondary light beam, the primary light beam to be emitted through the first surface and the secondary light beam to be emitted through the second surface, the secondary light beam comprising one or more characteristics indicative of one or more characteristics of the primary light beam; a mirror arranged to reflect the primary light beam emitted through the first surface of the beam splitter, the mirror to oscillate about at least one oscillation axis to scan the primary light beam; and a photodiode to receive the secondary light beam and to detect one or more characteristics of the secondary light beam, the photodiode configured such that a surface of the photodiode is offset from being parallel to the first surface and the second surface to reduce an amount of parasitic light directed to the mirror.
