class="relatedlink">测量</a>系统在非接触精密测量领域占有重要地位,其中对干涉条纹的测量是激光干涉测量的核心。针对这种情况,提出利用线阵CCD将激光垂直照射在劈尖表面时所产成的干涉条纹光学图像转换成电信号并转移输出,通过视频信号预处理<a href="http://electronic.oecr.com" target="_blank" class="relatedlink">电路</a>,模数转换后得到关于干涉条纹宽度的方度信号,完成了对CCD输出干涉条纹信号的处理,实现了对等间距干涉条纹的自动检测。<br /> Laser interference instrument is very important in uncontacted precision measurement field,the measurement of interference fringes is the key in laser interferometry.To deal with this problem,a linear CCD is used to induce the interference fringes and output electric signal when laser is shining optical wedge vertically,then the signal is preprocessed and transformed into square-wave signal which contain fringe width information.Signal processing from the output image signal of CCD is accomplished.The auto-testing for equally spaced interference fringes is realized.<br /> 关键词：线阵CCD 非接触测量 激光干涉 条纹宽度<br /> linear CCD ;non-contact measurement ;laser interference ;fringe width ;</td></tr></table> <div
