Vibration Damping
Two sources of need:1.Insure structural integrity under vibration2.Minimize image distortion
Item 1 must be tested for, but item 2 can be calculated and designed for.

Vibration Damping
• Characterized per RTCA DO-160• Frequency Range: 5 – 500 Hz• Amplitude Range: 0.00001 – 0.1 inches• 3 Primary Axes

Vibration Damping
• Image distortion depends on:– Aircraft Speed– Aircraft Altitude– Lens Image Angle– Shutter Speed

Vibration Damping
• Speed induced byvibration taken as derivative of vibration motion profile
• Profile:X = A·sin(F·t)
• Speed:X’ = A·F·cos(F·t)
