Sensation and Perception
However, rather than describing the grating in terms of fine or wide bars,
researchers use a measure called spatial frequency. 3 cycles (a) Spatial
frequency = 3 cycles/degree 1° 6 cycles (b) Spatial frequency = 6 cycles/degree 3
cycles Spatial ...
This volume presents an integrated view of how we perceive the spatial relations in our visual world, covering anatomical, physiological, psychophysical, and perceptual aspects.

The Essential Physics of Medical Imaging
If A = 0.10 mm, then one complete cycle would occur every 2A = 0.20 mm, and
thus in the distance of 1 mm, five cycles would be seen, corresponding to a
spatial frequency of 5.0 cycles/mm. The relationship between the distance
spanned by ...

The Perception of Visual Information
Bars that are closely spaced are said to have a high spatial frequency. Usually
they are more difficult to visualize than those that are widely spaced. A line pair,
composed of a light and a dark bar, makes up one cycle or period of a grating.

pupils in the integration is proportional to the spatial frequency. The integral is
zero outside the intersection of the pupils. The most important limitation is that
optical systems are low-pass spatial filter systems. The maximum frequency

The image in the lower left corresponds to what psychophysicists would call the “
low spatial frequency” channel. It contains the low spatial frequency information
in the image. Notably, it is mostly devoid of sharp edges. This information about ...

Fourier Methods in Imaging
In Equation (2.14), the spatial frequency of a real-valued sinusoid was shown to
be proportional to the rate of change of the phase angle. The definition of the
phase of a complex number in Equation (4.27b) may be used to extend the
concept ...

Handbook of Biological Confocal Microscopy
Spatial Frequencies and the Contrast Transfer Function Sampling theory, like
resolution itself, is often easier to think about accurately in the "spatial frequency
domain" where one considers not the size of objects themselves but the inverse
of ...
However, one could argue that this is nothing more than a restatement of the
spatial-frequency hypothesis developed by Sergent and her colleagues. Indeed,
the receptive field and spatial-frequency theories predict many of the same
results.
