Abstract
A device for measuring ultra-high speed phenomenon by using an optical beam. The ultra-high speed phenomenon can be measured at a high S/N ratio by composing either an object light or a reflected light from an object and a reference light using a polarizer, by generating a secondary higher harmonic from the composed light using a non-linear optical material, and by measuring the optical intensity of the secondary higher harmonic using a light receiving element.
