Abstract

We demonstrate an optical profilometer composed of an optical frequency comb source, a single pixel camera, and an optoelectronic interferometer in radio frequecny range. The system enables us to measure an object with a large depth much more than a light wavelength. The wide dynamic range is achieved by the high stability of the RF signal. The single pixel camera is used for two-dimensional imaging without a mechanical scanning, and the compressive sensing technique is used to reduce the number of measurements.
