FIELD: physics.
SUBSTANCE: solid is secured on bench provided with press, between plates of electromagnetic radiation capacitive pickup. Solid surface layer is strained by reciprocating power element to generate electromagnetic radiation signals in the process of crack formation. Said signal are converted by aforesaid transducer and registered. Said signal represents a sum of signal of EMR generated by heat electrons outgoing from surfaces of cuts, fractures and micro cracks and from surface for incised particles and signal generated by vibrations of solid surface strained sections with positive charges formed aforesaid surfaces after heat electrons escape and on surfaces of torn-off particles the vibration of which is caused by recoil pulses at the moment of their tear-off and electron escape. File made from material harder than that of solid is used as aforesaid power element.
EFFECT: generation of wide beam of electromagnetic radiation from large surface area.
