Abstract
Apparatus and methods of four wave mixing (FWM) holography are described, including illuminating a sample with a first beam, a second beam, and a third beam, and combining the generated FWM signal with a reference beam at a imaging device to obtain holographic image data. In some examples, the first and second beams may be provided by a single pump-probe beam. The third beam may be a Stokes beam or an anti-Stokes beam. A representative example is coherent anti-Stokes Raman holography (CARS holography), which includes illuminating a sample with a pump/probe beam and a Stokes beam to obtain a CARS signal from the sample; and combining the CARS signal with a reference beam to obtain a CARS hologram.
