Abstract

High resolution cameras rarely perform as expected in aircraft, often due to vibration problems. Proper understanding and use of classical dynamics for the whole system from optical axis to aircraft is necessary to quiet vibration enough for good photography. Shock mounting is different from quieting. The statement, "We get better results without isolators," is actually, "We get better results without shock mounts." Linear spring-mass-viscously damped systems are best, and if used, their performance can be easily predicted as shown. Passive vibration isolation systems will handle most problems. (Consider the automobile, the most successful example. ) What is needed is a very low frequency suspension with good viscous damping in all directions that isolates and damps all six degrees of freedom, three rotational and three linear.
