Nondestructive Testing of Local Microcracking in Laboratory Mineral Samples Using an Acoustic Method with a Laser Source of Ultrasound and Its Verification with X-ray Computed Tomography

An acoustic technique for nondestructive testing of the degree of local microcracking in laboratory mineral samples based on laser generation of ultrasound is proposed. The spectral power of broadband signals of longitudinal ultrasonic waves is measured. The waves were generated by absorption of pul...
