Characterization of materials with optically shaped acoustic waveforms
Patent
·
OSTI ID:1531559
A method for characterizing one or more properties of a sample using acoustic waveforms is disclosed, and comprises directing a sequence of at least three optical pulses to the sample to generate an acoustic response in the sample at a frequency corresponding to the pulse sequence, varying the timing of one or more of the pulses in the sequence to vary the frequency of the acoustic response in the sample, and measuring the strength of the acoustic response as a function of the varied frequency to determine information about the sample.
