Function Achieved in This Case
Enables error-free, automatic temperature compensation with a simplified configuration, ensuring correct radio frequency settings regardless of temperature fluctuations, thereby enhancing system operability and stability.
Implementation Method 1
The transducer usually consists of a piezoelectric material and an overlying and underlying electrode. By electrically connecting the two electrodes with radio frequencies, which are usually in the range between 30 MHz and 800 MHz, the piezoelectric material is made to oscillate, so that an acoustic wave (sound wave) is created
Implementation Method 2
Acousto-optical crystals, as they are used in the acousto-optical elements in question here, are characterized in that the resulting sound wave changes the optical properties of the crystal, with the sound causing an optical lattice or a comparable optically active structure, for example in the form of a hologram, is induced. Light passing through the crystal undergoes diffraction at the resulting optical grating
