光圈特性測試卡簡介
1、調制傳遞函數(shù)(MTF)應用于成像設備的解像力評價。
MTF的分辨率是由每個單獨的模塊(即對比度,鏡頭,成像裝置和放大器)的MTF綜合參數(shù)給出。
2、成像裝置通常使用方波圖卡的分辨率與振幅響應(AR)表達。
3、光圈響應卡是AR和分辨率光圈散光效果的評估測試卡。
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.
