METHOD OF DETECTING EXPLOSIVE CHARGE BLASTING CONTAINED IN TEST OBJECT, AND EXPLOSION DELAY FROM THE MOMENT OF THE TEST OBJECT CONTACT WITH OBSTACLE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC G01N21/31 F42B35/00 

FIELD: measuring equipment; test equipment.

SUBSTANCE: method includes registration of optical radiation in the spectrum of photodiode sensitivity, accompanying initiation of explosive charge (EC), in the test object (TO). Registration of optical radiation, accompanying initiation of TO content, with the help of at least two photodetectors, containing photodiodes, operating in photodiode mode. First photodetector is placed at the measurement site and radiation in front of and behind obstacle in the direction of TO movement is recorded. Second photodetector is behind an obstacle and records the radiation in blue spectrum, that enables recovering initial moment of ES detonation, located in the TO he with additional "parasitic" light strikings. Moment of collision with the obstacle is registered. Device comprises at least two photodetectors with photodiodes placed at the measurement site, operating in photodiode mode, connected to recorders. First photodetector records the radiation in the spectrum of photodiode sensitivity in front of and behind the obstacle in the direction of TO movement, contact sensor of breakdown type mounted on the front obstacle surface in the direction of TO movement. Second photodetector is placed behind the obstacle, light filter is installed at the input of the measuring channel of the second photodetector.

EFFECT: invention allows confirming the blasting charge and determining the time interval between test object collision with obstacle and blasting charge.
