Abstract:

Further study of the feasibility of the Pneumatic Energy Detector with Remote Optics PEDRO for evaluating the hazards of electromagnetic radiation to ordnance is reported. Measurements made on an electrically heated test fixture indicate a power input of 1.6 milliwatts to the one ohm bridgewire of a Mark 1 squib may be detected by diaphragm distention using an optical imaging technique. Correlation is made between the deflections produced by electric heating and by a static differential pressure across the mirrored diaphragm. The design of optical fiber configurations is discussed and prototype designs of the PEDRO sensing head are presented. Author
