Claim Text:
1. A system for facilitating multibeam coherent detection, the system comprising: a coherent light source; a first beam splitter that generates at least two beams from light emitted from the coherent light source; a second beam splitter that transmits a portion of the at least two beams as interrogation beams towards one or more target interrogation regions of a target to be interrogated and that redirects light counter-propagating with respect to the interrogation beams from the one or more target interrogation regions; and a third beam splitter that reflects a portion of energy from each of the at least two interrogation beams back towards the second beam splitter and transmits towards the second beam splitter the counter-propagating light with respect to the interrogation beams from the one or more target interrogation regions.
