Paper Abstract
A novel method of optical image registration using matrix of piezoelectric crystals is introduced. This technique allows measurement of beam profiles without using attenuation systems even at high power levels of incident radi- ation. Each element of the sensor matrix is the crystal piezoelectric resonator that has its own set of eigenmodes, which frequencies strongly depend on temperature. Due to an inverse piezoelectric effect the eigenmodes can be excited noncontactly via the application of the probe radiofrequency electric field providing that its frequency corresponds to any of the crystal eigenmode frequencies. Due to the residual optical absorption each element is heated in compliance with the incident radiation power. A calibration procedure is preliminary performed by transmitting collimated laser radiation separately through each single matrix element.
