Kato Lab
Machine-translated · View original
A lab that develops new technologies for optical measurement and control using optical frequency combs.
AboutAbout the lab
Developing new optical technologies.
The Kato Lab was launched in October 2022 and studies new applications of optical frequency combs (optical combs) and ultra-precise optical measurement methods.
An optical comb is broadband, phase-aligned light whose spectrum consists of lines evenly spaced on the frequency axis like the teeth of a comb.
The lab works on developing optical phased arrays and methods for measuring 3D shapes instantaneously.
It conducts joint research with the Minoshima Lab and the Asahara Lab in the same Department of Engineering Science.
Key terms
- Optical frequency comb
- Broadband, phase-aligned light whose spectrum consists of lines evenly spaced on the frequency axis like the teeth of a comb.
- Ultrashort pulse
- An extremely short pulse of light with a duration of only femtoseconds.
- Optical phased array
- A technology that controls the phase of light to form arbitrary wavefronts. This lab is taking on an approach that uses optical combs.

The lab develops new applications using optical frequency combs and ultra-precise optical measurement methods. Its research page focuses on the development of optical phased arrays and a method for measuring 3D shapes instantaneously.
*Illustrative imageOptical frequency combs (optical combs)
An optical comb is broadband, phase-aligned light that can generate a train of many femtosecond ultrashort pulses with highly precise control. It is used for high-precision frequency measurement and for improving the accuracy of distance measurement.
*Illustrative imageOptical phased arrays using optical combs
By controlling the cavity of an optical comb, the lab aims to create a fast, broadband optical phased array that forms arbitrary wavefronts with phase-controlled groups of ultrashort pulses. It is a challenge toward a new optical technology that directly controls space using the frequencies of light.
*Illustrative imageInstantaneous 3D measurement method
Using the interference between a chirped pulse train and a chirp-free pulse train emitted from an optical comb, this method converts distance information into wavelength information and measures 3D shapes without scanning. It achieves high speed, high precision, and a wide dynamic range at the same time.
