Abstract

We demonstrate cascade link multi-wavelength digital holography using optical frequency comb referenced synthesizer. This system expands the dynamic range of height in digital holography. In the experiment, 4 synthesized wavelengths and a single wavelength were cascaded, and steps of 10 mm and 21 µm are measured.
