Acousto-optic devices (AOD) which are intended for information transmission may be described by such parameter as information losses. This parameter determines the difference between information quantities in the input and output of the device. In order to estimate information losses in any AOD beforehand, it is necessary to find the sources of these losses in different links of the signal transmission and transformation in AOD. The comparison of AOD of different kinds have been performed from the point of view of information transmission possibilities. It has been found that the main sources of information losses are connected with the noise and limited information transmission possibilities of the devices. Proceeding from this conclusion, the basic ways to avoid the information losses in AOD have been listed. |
