1. A laser Doppler velocimeter comprising:

  • a source of radiation;

    at least a first bidirectional optical amplifier;

    a transceiver;

    a photodetector;

    an optical waveguide circuit coupling light from the radiation source, the first bidirectional optical amplifier, the transceiver, and the photodetector, the optical waveguide circuit comprising a first optical waveguide coupling light from the radiation source to an upstream side of the first bidirectional amplifier, a second optical waveguide coupling light from a downstream side of the first bidirectional amplifier with an upstream side of the transceiver, and a third optical waveguide connecting the upstream side of the first bidirectional amplifier with the photodetector.
