Abstract
A time-of-flight (ToF) optical beam splitter includes a main body having a first reflectivity and comprising a main surface configured to receive a receive light beam from an environment that corresponds to a transmit light beam transmitted into the environment, where the main surface includes a first region and a second region; and a reflective coating disposed on the main surface at the first region and excluded from the main surface at the second region, where the reflective coating has second reflectivity that is greater than the first reflectivity. The ToF optical beam splitter has a time variable splitting ratio with respect to the receive light beam that is dependent on a ToF of a round trip light beam comprising of the transmit light beam and the receive light beam.
