Video Sampling and Storage Device

This system utilizes a television camera, a video recorder, and a synchronized stroboscopic light source to provide an arrangement for analysis of high-speed mechanical motion.

Moving object 3 is viewed by TV camera 5 under illumination provided by strobe light source 7. A suitable sensing device, not shown, provides a triggering signal from object 3 to trigger sample circuit 9 which also has an input from video disk recorder 11. One output of circuit 9 actuates source 7 and the resulting image viewed by camera 5 is supplied by modulator-demodulator 13 and read- write amplifier 15 to the input of recorder 11. Sync line 17 synchronizes the readout of the camera image to recorder 11.

Information can be read out via amplifier 15 and modulator-demodulator 13 to X-Y coordinate analyzer 19 and TV monitor 20 to provide an enlarged image of the recorded video information. Analyzers 19 and monitor 20 can also be used for direct viewing of strobe-lighted object 3. Since recorder 11 requires the placement of video information on different tracks, circuit 9 provides signals to a sync count-down circuit 22 which, in turn, supplies an output to an advance circuit 24 via record-play control circuit 26. Signals are also supplied from recorder 11 to circuit 24 to thus operate address counter 28 which in turn controls the recording head multiplexing circuits 30.

In operation, images are recorded in a manner somewhat similar to conventional televis...
