[IP7-02] Multiscale profile measurement by using multi-wavelength FMCW-digital holography

*Hikaru Hamada1, Varun Kumar1, Masayuki Yokota1 (1. Shimane University)

We proposed multiwavelength digital holography using the hologram multiplexing in time-frequency domain based on FMCW technique. Three holograms recorded with different wavelengths were multiplexed, and the multiwavelength unwrapping was applied to measure the step object.
