非球面技术广泛使用于相机、手机、DVD、通信、天文、**系统等诸多领域中, 非球面镜头具有成像质量高、体积小、重量轻的特点。在非球面技术中，非常关键的一项就是非球面面形的测量。最早用于非球面测量的是接触探针法，经过长期的发展，其测量技术已日臻成熟，但难以兼顾高精度和高效率的要求。非接触式测量方法虽然也发展了近40年，先后出现了许多不同的测量方案，但依然存在难以实现高精度、高效率的问题。随着非球面制造技术的不断进步，人们对快速高效、高精度的非球面测量技术的需求日益迫切。根据不同的测量原理对各种测量技术进行了介绍和比较，指出其优缺点，进而对未来的非球面面形测量技术发展方向进行了预测。

Aspheric technologies have been introduced widely into numerous areas such as camera, cell phone, DVD, communications, astronomy, military affairs and so on because of its high image quality, compact volume and light weight. In aspheric technologies, a key problem is to test the aspheric surface. The probe-contacting method is the earliest one and has become more and more mature, but it couldn’t find a trade-off between high accuracy and high efficiency. The non-contacting methods have also been developed for almost 40 years and many different kinds of non-contacting styles are found. However, it’s still difficult to realize high accuracy and efficiency at the same time by using a non-contacting technology. With the development of aspheric manufacturing, it becomes more urgent to reach the goal of high accuracy in an extremely-short time. According to different testing principles, most popular aspheric testing technologies have been discussed and compared in details and their own advantages and disadvantages have been set forth. In the end, the developing directions of aspheric surface testing have been pointed out.
