The lens will degrade the contrast ratio of the stimulus to some degree, and the image modulation will therefore be a lower number than that of the stimulus. The modulation transfer function is the ...

Technical Terms Modulation Transfer Function (MTF): A quantitative measure of an optical system's capacity to transfer contrast at varying spatial frequencies from the object to the image.

Sharpness, Acutance and Resolution We show you how these important parameters affect the appearance of your photos. This article is a follow-up to the one on reading lens manufacturers’ Modulation ...

We developed a system that can measure the modulation transfer function (MTF) of a broadcasting camera in real time.

It shows how to use raysets, Modulation Transfer Function (MTF), slider wheels, tolerancing, and optimization. One section instructs on using Oslo’s built-in Compiled Command Language (CCL) as ...

The MTF MASTER IIT was specially designed to classify the quality of image intensifier tubes by the objective criteria of the MTF (Modulation Transfer Function). An object (haircoss) is projected with ...

The software is modular and produces monochromatic point-spread functions and modulation-transfer functions at intermediate stages. Details of known optical aberrations of the system, microroughness ...
