Abstract: An optical low pass filter(OLPF),lied in front of the sensor of a CCD camera, is designed according to the birefringent effect of crystal and infrared cut-of effect of in frareequency mixing phenol al filter, OLPF can reduce or eliminate effectively the fr menon whenthe object with a variety of the spatial frequencies is imaged on the discrete photoelectric detector ，and eliminate the color rendition effect of the infrared .The image quality of the CCD camera with OLPF can be improved. Especially, the distinctness can be enhanced when the objects such as fringes or grates are imaged on the sensor of the CCD camera, and the effects of the disturbing fringes of false color can be eliminated
Key words: optical low pas optics filter; Nyquist limit; aliasing; birefringent quartz crystal ; infrared cut-of light.
