Study on Automatic Measurement of Small Angles
Advanced materials research(2012)
摘要
This paper describes the automatic measuring principle of small angles, and through the design of optical structure of automatic measurement of small angle and the design of goniometer circuit, using the laser collimated light source and position of spot detector (PSD), with MCU-controlled A / D and digital display technology, automatic measurement of small angle has been achieved.
