A METHOD OF DIFFRACTION GRATINGPURPOSE:Production of holographic diffraction grating with good reproducibility.
We’ve seen similar work before, but the guide from [All3DP] goes into greater detail on how to get the effect to workjust right.Getting the bed as close to perfectly level is key here, as is the first layer height. This is because the first layer of plastic has to meld perfectly ...
An elegantly simple non–contact method is to measure the change in pitch of a reflective diffraction grating bonded to the surface of interest. The grating is probed with a laser beam and the change in angular position of diffracted orders is detected as the pitch changes due to surface ...
ruled这里是过去分词作形容词, Mechanical ruled 机械刻线的 diffraction grating 衍射光栅 整句Mechanical ruled diffraction grating is a kind of super-fine technology.机械刻线式衍射光栅是一种非常精密的技术。
The diffraction angles and efficiencies were controlled by the frequency and form of the light intensity modulation, respectively. With an optimized shape, obtained from a numerical simulation, diffraction efficiencies into a single order of more than 50% were achieved....
