几十年来，开发计量仪器的工程师在他们的产品中一直都使川运心透镜。例如，轮廓投影仪和光学比较器由于用了这种独特透镜面拥有许多测量功能。在过去一、二十年中，由干新技术使产品重点转向电子特性和数字处理，光学系统设计往往降到不太重要的地位，而期望用软件来校正较差 For decades, engineers developing metrology instrumentation have always been instrumental in their products. For example, contour projectors and optical comparators have many measurement functions thanks to this unique lens surface. Over the past one or two decades, the focus of new optical technologies has shifted the emphasis on electronic and digital processing to newer technologies, and the design of optical systems tends to be less important, with the expectation of software-based correction
