The Micro Four Thirds system (MFT) of still and video cameras and lenses was released by Olympus and Panasonic in 2008; lenses built for MFT use a flange focal distance of 19.25 mm, covering an image sensor with dimensions 17.3 × 13.0 mm (21.6 mm diagonal).
As an example, a telescope having an f /6 objective and imaging at 0.55 micrometers has a spatial cutoff frequency of 303 cycles/millimeter. High-resolution black-and-white film is capable of resolving details on the film as small as 3 micrometers or smaller, thus its cutoff frequency is about 150 cycles/millimeter.

The value of each data point in k-space is measured in the unit of 1/meter, i.e. the unit of spatial frequency. It is very common that the raw data in k-space shows features of periodic functions. The periodicity is not spatial frequency, but is temporal frequency. An MRI raw data matrix is composed of a series of phase-variable spin-echo signals.
