摘要
利用传像光纤束耦合的扫描系统成像时,由于加工工艺、光纤光传导特性以及光学系统的原因,相同照度的光线入射时,获得的图像亮度并不均匀。根据扫描成像的实际情况,对系统亮度进行定标,采用一点法校正,获得效果良好的图像。
In fiber bundles coupling image-scanning systems, the same intensity input rays will generate different gray level image due to optical nonuniformity originated from fiber fabrication process, transmitting attribute and optical system. According to the pratical circumstance of scanning, one point correction as well as pre-scaled method were introduced to get high quality image.
