Laser Beam Profile, Spot size and Beam Divergence
... can do this by slowly adjusting the laser in it’s support while checking the intensity pattern along two virtual horizontal lines at different heights on the beam cross-section. After this is done, we fix a distance for the detector and take intensity measurements of the beam along a horizontal line ...

A simple peak-to-average power ratio reduction
... (1). As aforementioned, | xn | reaches the maximum when n=0, and X k follows 0-1 distribution. Consequently, the maximum of | xn | can only be an integral number, varying from 1 to 16. Moreover, the expectation of | xn | is determined by X k , so that the average power of all optical OFDM symbols ch ...

A short introduction to light and electron microscopy
... It is useful to think of light as a probe that can be used to determine the structure of objects viewed under the microscope. Generally, the probes must have size dimensions that are similar to or smaller than the structures being examined (note: compare the probe size and resolution of electron mic ...
