    For the first time the possibility of the development and fabrication of the design nondetuned functional optical scheme of the laser heterodyne installation intended for the investigation of the amplitude and phase fields of surface acoustic waves (SAW). The design is characterized not by separate optical elements but the presence of the two units — probe unit and photo-sensor with minimal number of optical elements. This enabled to reduce errors during amplitude and phase measurements, because the installation setup provides high sensitivity to the small amplitude of SAW and good reproducibility of the results. The optical scheme of the device is presented operation principle is described as well as the results of some investigations.
