Abstract: Approaches, apparatuses and methods for single photon sensitive, non-interferometric photonics vibrometry applications based on quantum parametric mode sorting, optical gating and single photon counting are disclosed. In one embodiment, a controller module includes a photon detection unit, a pulse generator unit, a time synchronization unit, a data acquisition and processing unit and a central controller unit. In the second embodiment, a probe module with beam raster scanning ability includes an optical transceiver unit based on a bidirectional monostatic coaxial arrangement using off-the-shelf optical components and an optical beam steering device.
