With the development of science and technology , a lot of instruments and equipment are toward miniaturization , integration direction, and the performance is more excellent . Optical instrument is the same , it is the object of study is no longer a traditional lenses, prisms , gratings , etc. , but the emerging integrated optical systems . Integrated optical system has a faster response , better reliability , cost and miniaturization advantages. Microlens array is the basis for integrated optical components are tiny precision devices, which put a lot of tiny lenses regularly integrated into a larger lens substrate, thus directly face a problem is how to quickly and effectively on the base slice thickness is qualified measurements. Here are ready to design an optical measurement system. This article first briefly introduces the related knowledge of microlenses , including microlens background , definitions, scope of application and the manufacturing method ; then carried out based on optical triangulation optical system demonstration, show that the accuracy of the measurement system can meet the requirements of measurement tasks ; subsequently proposed to the design of the measuring circuit system solutions to the system so that we have an overall understanding ; thus describe in detail the various parts of the program specific method . Part of the measuring circuit , described in detail the working principle of CCD , and the CCD CPLD selected drive mode , using Verilog HDL language to complete the driver circuit design , while the driving pulse tested verification ; more detailed description of the USB protocol , same time a USB transfer circuit design, which enables fast data transfer. Designed the main chip DSP, and its peripheral circuits , allowing DSP to coordinate the work of the entire circuit , the article details the DSP workflow. In this paper, a separate chapter during the programming method based on the comparison carried out about the PC software programming , including programming platform Borland C Builder software selection and implementation of each part , there is monitoring software features USB -off from the USB port read data , data processing , and other graphics rendering . Finally, the design of the entire system debugging , debugging to get the expected success, and in the paper attached debugging results .
