为了用统一的表征参数和测试手段来公正地评价投影机的光学参数,以及向投影机设计者们提供相关的光学参数,从而达到修正设计的目的。现根据投影机的主要光学参数的计算及测量方法,采用美国国家标准的测量模型,利用单片机设计了一款通用的投影机光学参数测试系统。并测试了多款投影机的相关光学参数。该测试方法能精确地测量投影机的相关光学参数,是一款通用高效的测试系统。

In order to use unified characterization parameters and test means to fairly evaluate the optical parameters of the projector, and provide the projector designers the optical parameters to achieve the amendment. According to the main optical parameters of the projector calculation method and measurement methods, the design uses the measurement model based on ANSI and microcontrollers to design a universal testing system. And a variety of optical parameters of the projectors are obtained by the system. This test method can accurately measure the optical parameters of the projector. It is a versatile and efficient test system.
