光圈特性测试卡简介
1、调制传递函数(MTF)应用于成像设备的解像力评价。
MTF的分辨率是由每个单独的模块(即对比度,镜头,成像装置和放大器)的MTF综合参数给出。
2、成像装置通常使用方波图卡的分辨率与振幅响应(AR)表达。
3、光圈响应卡是AR和分辨率光圈散光效果的评估测试卡。
1.Modulation Transfer Function(MTF) is applied to image assessment for an imaging device.
The MTF resolution is given by the product of the MTF of each separate module (I.e. contrast, lens, imaging device and amplifier).
2.Resolution of imaging device on using a square-wave chart is generally expressed with Amplitude Response(AR).
3.Aperture Response Chart is a chart for evaluation of astigmatic effect of AR and Resolution Aperture.
