One-shot three-dimensional measurements with a fiber bundle using a chirped optical frequency comb

We developed a one-shot multi-point three-dimensional (3D)-measurement method using a bundle composed of 55 multi-mode fibers based on ultrafast space-time-frequency conversion with a chirped optical frequency comb. We demonstrated measurement of the 3D profile of a reflective object by one-shot imaging using the fiber bundle with micrometer accuracy.

Non-scanning three-dimensional imaging using two-dimensional spectroscopy and spectral interferometry with a chirped frequency comb

Non-scanning three-dimensional imaging with a chirped-frequency comb is demonstrated using two-dimensional (2D) pulse-to-pulse spectral interferometry and 2D spectroscopy. The profile of a structure of three gauge blocks was measured with μm-level uncertainty.
