Research on a New Type of Contactless Length Measurement Device
In this paper,a non-contact length measuring device is developed,which consists of linear moving u-nit,laser ranging unit and optical positioning unit.By combining the relevant unit components,the non-contact measurement of the measured sample is realized,and the problem of low measurement accuracy is solved when the measured sample has irregular shape or the size value of a specific area needs to be measured.The device is simple to operate,and it does not need to configure the closed detection space required by the long grating device to meas-ure,which improves the detection efficiency.
