METHOD FOR GENERATING LARGE AREA HOLOGRAPHIC GRATING AND APPARATUS THEREOF |
摘要 |
PURPOSE: A method for generating a large area holographic grating and an apparatus thereof are provided, which fabricates a large area grating below an effective area of a lens as using an optical system of small caliber. CONSTITUTION: A light projected by an ultraviolet ray laser(10) of a single wavelength is focused to a pin hole(14) with an object lens(12) and then passes through a spatial lens removing noise in the air, and then the beam extended using a collimating lens(16) and passes through an inverse Gaussian transparent filter(22) and is irradiated to a sample(18) in parallel. The sample is located to have an angle to a path of the light, and a mirror(20) is attached to the sample so that a reflected light has a specific angle with the incident light to control an interval of an interference pattern.
