It wasn't until Albert Einstein explained the photoelectric effect and realized that light energy had to be quantized that the particle theory returned.然而,在19世纪,光的波动性(我指的是一般的电磁辐射)变得昭然若揭,科学家们已经基本上把光的粒子理论扔出窗外了。直到爱因斯坦解释光电效应并意识到光子...
In the 1800s, however, the wave properties of light (by which I mean electromagnetic radiation in general) became glaringly obvious and scientists had essentially thrown the particle theory of light out the window. It wasn't until Albert Einstein explained the photoelectric effect and realized that...

It is determined by the number of light-sensitive elements on the photoelectric sensor in the camera, and a light-sensitive element corresponds to one pixel. Thus, the larger the pixel, the more light-sensitive elements, the greater the corresponding cost. The image quality of digital cameras ...
The optical fiber sensors are divided into two categories: thrubeam and reflective. The thrubeam type comprises a transmitter and a receiver. The reflective type, which is a single unit, is available in 3 types: parallel, coaxial, and separate. The 3 are based on the shape of the crosssec...
