Design and performance of a 20-stage digital light beam deflector
Applied Optics
|February 2, 2010
Abstract:
This paper gives optical design considerations and experimental results of a 20-stage digital light beam deflector consisting of a series of nitrobenzene Kerr cells and birefringent calcite prisms. The laser beam is deflected into a two-dimensional raster of 1024 by 1024 positions with a deflection rate of 500 kHz. The optical transmission of the deflector itself is 79% for green laser light. Data about background light and resolution as well as display examples showing alphanumerics and graphics are given.

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...

01:17Design Example: Calculating Safe Diameter for Wind-Exposed Disc
Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...
