The X-Ray Motion Monitor provides a new and versatile tool for experiment and research work in the field of biodynamics. The equipment essentially consists of a pulsed x-ray source synchronized with a closed circuit TV system, utilizing a fluorescent intensifying screen to convert the x-rays into a visible pattern. The head portions of the equipment are designed to withstand acceleration up to 147 meterssq sec while rigidly mounted to a test platform, and up to 392 meterssq sec on special shock fixtures designed for drop tests. The light output of the fluorescent screen is matched with the spectral response of the image orthicon tube in the TV camera to provide peak performance while employing extremely low x-ray dosages. The x-ray source is pulsed on for only 116 of the total observation time 1 millisecond for every 16.7 milliseconds. The system permits visual observation, andor cine or video tape recording, of an x-ray view up to a size of 20 by 30 inches of the internal organs of a live test subject while under acceleration or shock. In addition, special video processors in the system provide voltage analog outputs corresponding to the movements of selected internal targets in relation to some fixed internal or external reference points. These analog signals can be recorded by graphic recording devices for reference and later analysis. Author
