Based on a hybrid opto electrical image processing system with an incoherent correlator, the image matching algorithm using optical Walsh transformation is realized successfully.

基于以非相干光相关器为核心的光电混合图像处理系统，实现了基于光学沃尔什变换特征提取的图像匹配算法。

Rather than by forming an image or a picture you put electrodes on the surface of the body and measure the electrical potential as a function of position on the body.

它并不对人进行直接的造影,而是将电极放到身体表面,通过测量该位置电势能,表征该部位的生理状态

This microscopic scale and sensitivity allows the sensor to map a high-resolution image of electrical charge that occurs over the surface of a source material (for example a human finger), when it makes contact with a thin insulating surface (ie a plastic surface).

FORBES: Can Forensic Scientists Tell How Old A Fingerprint Is?

When I gave a TEDGlobal talk on femto photography in June, I began with a reference to Doc Edgerton, a very popular MIT professor of electrical engineering who, in 1964, wowed the world with an image of a bullet in midair, having just passed through an apple.
