By two laser triangulation  a small thickness measurement system based on PSD and FPGA is presented. It takes S3931 PSD of one dimension as position detection device  A FPGA produces logic control signals for the whole system  the small displacement is converted to differential voltages  which is made by Hamamatsu in Japan  and after amplification and A/D transformation  8-bit parallel data is send to singlechip from FPGA by external interrupts  and the final calculation results output to the LCD display module. After digital micro meter calibration  we get the small thickness. Experiments show that the detection accuracy of the system is not less than 10um.   A New Surface Inspection Method of TWBS Based on Active Laser-triangulation 会议论文  OAI收割 7th World Congress on Intelligent Control and Automation, Chongqing, China, June 25-27, 2008 作者:  Zhang L(张雷);  Zhao MY(赵明扬);  Zou YY(邹媛媛);  Gao SY(高世一) 收藏  |  浏览/下载：61/0  |  提交时间：2012/06/06 image processing  surface inspection  weld defect detection  Laser-triangulation   Optoelectronic non-contact measuring method for the taper of a bore (EI CONFERENCE) 会议论文  OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China 作者:  Zhang G.;  Zhang G.;  Zhang G.;  Yang L.;  Yang L. 收藏  |  浏览/下载：40/0  |  提交时间：2013/03/25 Based on laser optical triangulation displacement and grating displacement inspecting principle  optoelectronic non-contact inspecting method and inspecting system for the taper of small-calibre bore are presented. In this paper  the constitute and overall structure of the system are described. Then  the taper inspecting method and principle of the bore are discussed and theoretically analyzed  and also  the corresponding mathematics model is established. As inner diameter measurement is an important parameter for the taper of small-bore  an inner diameter laser non-contact measuring method is presented based on the structure characteristic of the taper of small-calibre bore  which adopted optoelectronic probe sensitive device (PSD) and laser optical triangulation inspecting principle. And then  the laser probe inner diameter measuring system is designed based them. Moreover  the measuring principle  the project of optical system of this measuring system are illuminated in detail in this article. The accuracy of inspecting system is verified by experiment. The results showed that the measuring error of inspecting system is superior to 0.005  and the inspecting repetition is superior to 0.003. It indicates that the system can fulfill the inspecting accuracy demand for inspecting the taper of the small-calibre bore  and the inspecting method is applicable.
