激光或单色LED作显微光源——无色差无干涉条纹光学显微摄影和双重单色光照明的探究
Laser or LED Light Source for Microscopy——No Chromatic Aberration No Interference Fringe Optical Microscopy and Double Monochromatic Lighting Photographic Exploration
单色光作显微光源 无色差 无干涉条纹 多重单色光多角度复合照明 laser or LED light source for microscopy no chromatic aberration no interference fringe multi-angle composite multi-monochromatic lighting
摘要
如果采用单色LED作光源，由于LED属非相干光源，因此能在消除色差的前提下避免成像时的干涉条纹现象；如果采用激光二极管作光源，通过高频轻微震荡激光光源等方法，也能使人眼或摄影仪看不到相干条纹，提高图像清晰度。
Abstract
If monochromatic light-emitting diode light source, because LED is a non-coherent light source, they are able to eliminate chromatic aberration to avoid the interference of the premise. If the LD source, through minor and high-frequency tremors of light source and other methods, but also the people's eyes or photographic instrument can not see interference fringe, to improve image clarity.
