Wavefronts: A wavefront is an area that represents the points in a wave that vibrate together and have the same type of motion. It is called a wavefront because it describes the activity of a wave and it applies to a particular surface. ...

What is the working principle of the spectrometer? Explain Einstein's theory of relativity in simple terms. According to Huygens, how does every point on a wavefront behave? Use the Huygens principle to explain how plane parallel wavefronts are diffracted at a single aperture. ...
In geometrical optics, light is modeled using the ray approximation. In the ray approximation, light wavefronts are approximated as a collection of rays, each perpendicular to the wavefront of light and representing the energy flow through the system. A typical application of geometrical optics ...
However, there are a few unifying factors amongst laser optics. First, they almost invariably need to maintain the original wavefront quality of the laser beam. This is essential to preserving the very qualities that make laser light unique, like spatial brightness and coherence. Wavefront distorti...
A single small light source sends out electromagnetic waves in all directions as shown above. Of course these diagrams are only two-dimensional, while the real situation is 3D. We can visualize a coherent wavefront to be spherical. The waves are like layers of a spherical onion, but where ...
The SLMs discussed in this review consist of miniature liquid crystal displays with micron-sized pixels that can modulate the phase and/or amplitude of an optical wavefront. In microscopy they can be used to control and shape the sample illumination, or they can act as spatial Fourier filters...
If this were a singlet (1 element lens) it would translate to about a 1/10 wave wavefront error. The problem is that there are 6 total surfaces in a triplet, each having its own small aberration. When you place them together they can add up to a large final error. In any case, ...
