[Technical Data Presentation] Publication on real-mode measurement targeting long-duration measurements.
This document is a technical report explaining real-mode measurement targeted at long-duration measurements. In the heterodyne processing system, we constructed measurement technology in real mode. The main focus of the construction was the signal processing device. We confirmed the operation according to theory using a synthesizer and verified a resolution of less than 1 nm. Additionally, we obtained the operational range of various parameters. Using this device, we conducted measurements in air and inside a vacuum chamber with a standard optical system.

Company information
We have established 'High-precision measurement of physical quantities using light' as our management policy. Optical measurement technology has become an indispensable element of modern cutting-edge technology. We are confident that the demand for high-precision measurement will grow stronger with the advancement of science. By combining high-precision measurement with the excellent properties of light—non-invasive, non-intrusive, non-contact, and high-precision—we can expect further technological innovation. It may not be suitable for measuring mass-produced items, nor for online measurements. However, we are committed to making it useful for cutting-edge industries that require high-precision measurement of physical quantities.
