Light beam deflection using holographic scanning techniques
Applied Optics
|January 15, 2010
Abstract:
Holographic techniques provide a mechanically simple method for deflecting light beams through two-and three-dimensional scan patterns. One technique for producing a two-dimensional raster scan through the use of a one-dimensional circular motion is described in detail. To illustrate the feasibility of such devices, a two-dimensional holographic scanner has been fabricated and used to construct a simple closed-circuit television system.

01:19Deflection of a Beam
Accurately determining beam deflection and slope under various loading conditions in structural engineering is crucial for ensuring safety and structural integrity. Singularity functions offer a streamlined approach to analyzing beams, especially when multiple loading functions complicate the bending moment equation.
Singularity functions, described in an earlier lesson, are powerful mathematical tools that represent discontinuities within a function commonly encountered in structural loading...

01:16Confocal Fluorescence Microscopy
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
