ITE Aperture Response Chart

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).Resolution of imaging device on using a square-wave chart is generally expressed with Amplitude Response(AR).Aperture Response Chart is a chart for evaluation of astigmatic effect of AR and Resolution Aperture.
