Research abstract
THE CONCEPT PROPOSED IS AND ELECTRO-OPTIC TECHNIQUE THAT WOULD MAKE IT POSSIBLE TO SPATIALLY MODULATE A HIGH POWER PULSED LASER BEAM TO THERMOELASTICALLY INDUCE FOCUSED ULTRASOUND IN A TEST MATERIAL. BEING A PURELY ELECTRO-OPTICDEVICE, THE MODULATOR, AND THEREFORE THE DEPTH AT WHICH THE ACOUSTIC FOCUS OCCURS, CAN BE PROGRAMMED ELECTRONICALLY AT ELECTRONIC SPEEDS. IF SUCCESSFUL, IT WOULD BECOME POSSIBLE TO SCAN A SOUND CONTINUOUSLY IN THREE DIMENSIONS WITHIN THE COMPONENT OR STRUCTURE UNDER TEST.
