Abstract

PURPOSE:Distance of several meters is measured at accuracy of about 1mm with an inexpensive by radiating modulated light to a target, and measuring the distance of the target based on the resonance frequency of the modulated waves of the light when the reflection space is regarded a resonator for light.
