Poisson spot played an important role in the discovery of the Optical Wave nature of light , here is how to simulate and demo it .
As an laser optics engineer, we always expect to quickly have the laser beam specs in an system without complicated calculation,Here we share how to do it
when we could we use “ray based simulation”, and what is the condition we could use the ray to represent the Laser source
In many laser propagation applications, it is important to quickly capture the key points of laser beam specs, what is the key? this article will share!
An understanding of the wavefront is an important in the Laser optics, fiber optics, How to predict and analyze it, this article will help you a bit.
Zone plates are used in photography in place of a lens, soft-focus image，and may be used as imaging lenses, but how to model it, here it is！
Phase, Phase radius, Gaussian beam, divergence angle, pilot beam, phase data, Rayleigh range…here we share how to interpret them!
The physical optics model is generally more accurate at predicting the detailed amplitude and phase structure, here we share a few examples how to do it!
in photolithographic applications, the sources used are not fully coherent, how to analyze the mask in a partial coherent imaging system onto a wafer?
