两种不同类型的滤光片式彩色亮度计性能比较

Performance Contrast of Two Different Types of Optical Filter Color Luminance Meter

显示器的色度和亮度可以通过彩色亮度计进行测量。小视场滤光片式彩色亮度计因其低成本在生产线上应用广泛,而近来出现的影像式彩色亮度计虽然也属滤光片式,但是由于其探测器不同而具有大视场,且结构、原理和性能与前者都有差异。量化比较这两类滤光片式彩色亮度计的性能,可以为影像式彩色亮度计的质量评估提供依据。文章分别选取两类滤光片式彩色亮度计中的代表型号,通过进行原理分析和实验验证进行对比分析。结果表明,影像式彩色亮度计的性能不低于小视场滤光片式彩色亮度计。

The luminance and chromaticity of monitors are measured through color luminance meters.Small-field optical filter color luminance meter is widely used in production line for its low-cost.Image color luminance meter,as a new product,is also a kind of optical filter color luminance meters.But it is large-field because of the different detector.Its structure,principle and performance are also different.Making performance contrast between these two kinds of optical filter color luminance meters helps estimating the image color luminance meter＇s quality.This paper makes a performance contrast between the two kinds＇ representative through principle analysis and experiment.It turns out that the performance of the image color luminance meter is no worse than the small-field optical filter color luminance meter.
