Abstract
The complex motion associated with machines is a result of the superposition of various frequencies from the multiple component or elements inherent to the design of the machine. These motions can be captured remotely using position sensitive detectors which respond to specific wavelengths in the electromagnetic spectrum. Present embodiments include but are not limited to a video camera which is able to capture and record video data of an entire machine without contacting the machine, to visually study complex motions which vary both in time and spatially at different locations on the machine, wherein filters applied to the motion present in the video recording are used to identify frequencies of importance and to visualize their impact on the operation of the machine.
