Title: Optical system for wavelength monitor for laser beam
Inventor: NIIHORI MASASHI
IPC: G01J3/26
Filed: 2000-11-15
Abstract: PROBLEM TO BE SOLVED: To reduce a light quantity required for wavelength measurement to the utmost, and to prevent energy from being concentrated in a photoreceiving face. SOLUTION: Light incident via a beam splitter 1 diverges in an crossed cylindrical lens array 2a to get incident into an etaron 3, a fringe image formed by the etaron 3 is image-focused on a linear array sensor 5 by a projection optical system 4. An irradiated area on a linear array sensor 5 surface is brought into a size substantially equal to the linear array sensor 5 by using the lens array 2a having surface and reverse face focal distances or lens pitches as a diffuser for diverging the incident light getting incident into the etaron 3. Since the light is diverged in both vertical and lateral axes, the energy is prevented from being concentrated in the photoreceiving face, and a life of the sensor is prolonged. A rectangular microlens array is allowed to be used instead of the crossed cylindrical lens array.
