最近开发的一种使用具有降低容差要求的空间滤波器的模式识别方法被用于生成主要包含相位信息的滤波器。正如预期的那样，识别水平有所下降，但它们仍然足以进行明确的识别，并具有可观的失真免疫力。此外，滤光片的信息内容与空间光调制器等低分辨率设备兼容。
A recently developed approach for pattern recognition using spatial filters with reduced tolerance requirements is employed for the generation of filters containing mainly phase information. As anticipated, the recognition levels were decreased, but they remain adequate for unambiguous identification together with appreciable amounts of distortion immunity. Furthermore, the information content of the filters is compatible with low resolution devices like spatial light modulators.
