Understanding resolution and MTF - Norman Koren

Feb 26, 2007 · MTF is the spatial frequency response of an imaging system or a component; it is the contrast at a given spatial frequency relative to low frequencies. Spatial frequency is typically measured in cycles or line pairs per millimeter (lp/mm), which is analogous to cycles per second (Hertz) in audio systems. Lp/mm is most appropriate for film cameras, where formats are relatively fixed (i.e., 35mm ...

VCV Manual - Voltage Standards

Modules should use the 1V/oct (volt per octave) standard for CV control of frequency information. In this standard, the relationship between frequency f f f and voltage V V V is f = f 0 ⋅ 2 V f = f_0 \cdot 2^{V} f = f 0 ⋅ 2 V, where f 0 f_0 f 0 is the baseline frequency. Your module might have a frequency knob which may offset V V V.

Introduction to Modulation Transfer Function | Edmund Optics

The spatial frequency is expressed in terms of cycles (or line-pairs) per millimeter. The inverse of this frequency yields the spacing of a line-pair (a cycle of one black bar and one white bar) in millimeters. The nominal MTF curve is generated using the standard prescription information available in optical design programs.
