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.
