Description/Abstract:
THIS PROJECT'S OBJECTIVE WAS TO EVALUATE A HIGH-SPEED ELECTROMECHANICA L SHUTTER THAT HAD BEEN DEVELOPED AS A PROTECTIVE DEVICE AGAINST FLASH BLINDNESS. THE SHUTTER WAS TESTED DURING FIVE SHOTS BY THE USE OF ANI MAL AND HUMAN SUBJECTS. THE THERMAL ENERGY INCIDENT ON THE SHUTTERS R ANGED FROM 0.0347 TO 0.1804 CALORIES/SQ CM. ILLUMINATION INCIDENT ON THE SHUTTERS RANGED FROM 13,200 TO 120,000 LURNENS/SQ FT. THE SHUTTER CLOSURE TIME WAS 550 PLUS OR MINUS 50 MICRO SECONDS. RECOVERY AFTER EXPOSURE OF VISUAL EFFECTIVENESS OF PERSONNEL PROTECTED BY THE SHUTTER WAS INSTANTANEOUS AND COMPLETE, WHEREAS UNPROTECTED ANIMALS RECEIVED CHORIORETINAL BURNS. IT WAS CONCLUDED THAT A SHUTTER OF THE TYPE TEST ED DURING THIS OPERATION OFFERED PROTECTION FROM FLASHBLINDNESS. THE ELECTROMECHANICAL SHUTTER WAS SUFFICIENTLY DEVELOPED TO BE INCORPORATE D INTO A GOGGLE FOR SERVICE TESTING. A SIMPLE RELATIONSHIP IS ALSO GI VEN FOR SCALING PEAK PHOTOMETRIC ILLUMINATION AGAINST PEAK THERMAL IRR ADIANCE.
