Measurement method for high temperature surface profiling using laser radar system |
| |
| Abstract: | In general,the measurement of surface profile of a high temperature body is a difficult problem.We employed a laser radar system,including a laser phase rangefinder,to measure the surface profile of a hot body,and achieved the better measurement precision of 1 cm.In order to achieve higher SNR,we used the view field matching technology of laser emission and receiving,the technologies of laser beam intensity modulation,phase discrimination,and high sensitive APD detector. |
