Practical experience in the transmission of high optical powers along
a fiber optic cable.
The continuous power densities
were as high as one million watts/sq. cm2. The primary concerns
Threshold, Remote Alignment, and re‑collimation of the exit beam.
A 40 foot diagonal
High Definition (HDTV‑1250) Television picture
was projected onto a screen
at a demonstration in Paris on October 4, 1989.
The support provided included the reduction of residual
crosstalk, hum, noise,
and the improvement of the frequency response of the
video/timebase corrector chain.
Evaluations were made to establish the features and performance of
the final design
and programming of a 120 degree laser video projection system for the
Italian Pavilion, Expo '92, Seville, Spain.
Design and programming of a high precision turret/zoom
system for the Laser Video Projector.
PID analysis and backlash control.
Easy, convenient user interface developed for audiovisual applications.
(80c196 Embedded Servo Controller,
from Hi-Tech 'C' under IBM PC-AT(MS-DOS),
80c196 Assembly Language.)
Design and programming of a GUI style remote control interface for the
Laser Video Projector.
(IBM PC-AT(MS-DOS), Windows SDK 3.1)
Other R&D assignments performed:
Installation and programming of a multi‑station
laser light show system for Rock Circus, London, England.
