| Abstract: | Methods and characteristics of opto- electrical signal processing of heterodyneinterferometer are described and analysised in this paper. Their applying fields are showed. At the sametime a new opto-electrical processing method is introduced. With the new method the heterodyneinterferometer can not onlu be used to measure dynamically. but also reach to a high measurementtesolution. |
