Optical transfer function: Measurement, Factors affecting MTF in typical camera systems & Examples

The optical transfer function (OTF) of an optical system such as a camera, microscope, human eye, or projector is a scale-dependent description of their imaging contrast. Its magnitude is the image contrast of the harmonic intensity pattern, 1 + cos ⁡ ( 2 π ν ⋅ x ) {\displaystyle 1+\cos(2\pi \nu \cdot x)} , as a function of the spatial frequency, ν…
