Popis:	The ultrasonic beam features in ultrasonic and acousto-optic devices have a great impact on their characteristics and need to be studied. In the current work, a conventional optical visualization technique was extended to include spatial ltration of the light di raction pattern and stroboscopic illumination of a unit under test. That enabled very weak light responses from ultrasonic waves to be observed. This technique was applied to studying propagation and re ection of ultrasonic pulses in the TeO2 crystal, a body of the total internal re ection ultrasonic sensor. Analysis of visualization data has revealed an unexpected conversion of the shear horizontal wave radiated by the transducer into a longitudinal one on its normal re ection from the (001) face of the crystal, which is inexplicable as far as the plane wave theory is concerned. This nding requires further research to be con rmed and explained.
