광 Pick-up용 Micro Fresnel Lens의 회절 효율 시뮬레이션
Simulation estimate of micro fresnel lens for optical pick-up
초록
In optical pick-up systems, it's important of the efficiency of lens. We had simulated and estimated the efficiency of micro fresnel lenses which designed according to various focal lengths and wave lengths. Also we had simulated and estimated the micro fresnel lenses with a step-shape which number of steps are 2, 4 and 7. Through studies on between step_shape and design factor, we have obtained a proper number of step-shape fresnel lens for manufacturing that.
