Abstract
Systems and methods for a silicon photonics integrated optical velocimeter are provided herein. In some embodiments, a method includes producing a laser output at a laser source; emitting the laser output from a plurality of emitters formed in an optical chip; receiving a plurality of reflected portions of the emitted laser output at an optical collector formed in the optical chip, wherein the plurality of reflected portions are reflected off of at least one surface; beating the laser output against the reflected portions of the emitted laser output, wherein one of the laser output or the reflected portions of the emitted laser output are modulated by at least one modulation frequency; and calculating a doppler shift for each of the plurality of reflected portions of the emitted laser output based on an output of the beating and the at least one modulation frequency.
