Abstract
A holographic imaging system comprises an imaging light source defining an imaging light path, an active light source defining an active light path directed at a target, and a polarizer configured to modify the polarization of the active light path. The system further comprises a polarization beam splitter positioned in the active light path and the imaging light path, configured to separate the active light path and the imaging light path, and a photodetector positioned at a terminus of the active light path. The photodetector is configured to measure a reflection of the active light source. A method of holographic imaging is also described.

A holographic imaging system, comprising:
- an imaging light source defining an imaging light path;
- an active light source defining an active light path directed at a target;
- a polarizer configured to modify the polarization of the active light path;
- a polarization beam splitter positioned in the active light path and the imaging light path, configured to separate the active light path and the imaging light path;
- and
- a photodetector positioned at a terminus of the active light path, configured to measure a reflection of the active light source.
A method of holographic imaging, comprising:
- projecting an active light source toward a target;
- projecting an imaging light source toward the target;
- modifying the polarization of the active light source;
- merging active light from the active light source with imaging light from the imaging light source so that the active light and the imaging light strike the target coaxially;
- separating active light reflected from the target from imaging light reflected from the target using a polarization beam splitter;
- and
- measuring the active light reflected from the target with a photodetector.
