轨道角动量（OAM）的生产，通过使用q板，其功能作为一个电可调的空间频率滤波器，提供了一个简单而有效的方法，在生物和医学样本成像的边缘对比度的组织，涂片，和PAP涂片的组织学评价。类似于高通空间滤波器的使用，位于4f透镜系统的傅立叶平面处的产生OAM的仪器（诸如q板）允许高空间频率通过，并且使得能够产生具有与不透明和透明物体的暗背景形成对比的高度照亮的边缘的图像。与普通的螺旋相位板和空间光调制器相比，q板具有电控和可调谐的优点。
The production of orbital angular momentum (OAM) by using a q-plate, which functions as an electrically tunable spatial frequency filter, provides a simple and efficient method of edge contrast in biological and medical sample imaging for histological evaluation of tissue, smears, and PAP smears. An instrument producing OAM, such as a q-plate, situated at the Fourier plane of a 4f lens system, similar to the use of a high-pass spatial filter, allows the passage of high spatial frequencies and enables the production of an image with highly illuminated edges contrasted against a dark background for both opaque and transparent objects. Compared with ordinary spiral phase plates and spatial light modulators, the q-plate has the added advantage of electric control and tunability.
