Vibration effects can be a maj or limiter in the performance of optical instruments used for guidance, control, surveillance
and observation. The author has recently developed software that takes the physical prescription data for the optical
system, calculates the influence coefficients between all the elements in the system and the system's image and then
prepares a NASTRAN finite element model ofthe optical imaging behavior. This model can be added to the elastic
model ofthe optical instrument and NASTRAN can then calculate all the motions ofthe image on the detector. This
paper describes the use of the Ivory Optomechanical Modeling Tools in analyzing optical instruments in vibration
environments and uses a recent FUR project as a practical example oftheir utility.
