below are short courses which are offered
by Sigmadyne. These courses may be offered
at your location and are also held in Rochester,
NY if the interest exists.
Description
The purpose of this course
is to present opto-mechanical modeling methods
used to design and analyze high performance
optical systems. The primary goal addresses
the integration of thermal and structural
responses into optical design software packages
to predict optical system performance. A
second emphasis of the course is to discuss
thermoelastic and structural modeling methods
using finite element tools to analyze and
predict the integrity and performance of
optical elements and optical support structures.
Examples will be drawn from ground-based,
airborne, spaceborne, commercial, and military
optical systems subject to various optical
performance criteria and service environments.
Prerequisite
/ Intended Audience
This course is intended
for mechanical, structural, thermal, optical,
and system engineers interested in learning
finite element modeling methods specific
to optical systems and techniques to integrate
thermal and structural responses into optical
design codes. Review topics in mechanics,
finite element theory, and optical analysis
are covered briefly. A BS degree in mechanical/civil/optical
engineering and a fundamental understanding
of the theory and application of the finite
element method is highly recommended.
