Abstract
A device includes a sensor, a coherent infrared illumination source and optics to direct an infrared reference beam to the sensor. The sensor is positioned to capture an image of an interference signal generated by an interference of the infrared reference beam and a wavelength-shifted exit signal. The wavelength-shifted exit signal propagates through the optics before interfering with the infrared reference beam.
