Veillance Flux: The ability to see, hear, or sense.

How does the ability to see move through space?

This new research discovered the "veillance field" which is emitted by eyes, cameras, and other sensors, and travels through space in the opposite direction to normal light.

This discovery led to the new field of extramissive optics, which complements the traditional field of energetic optics. They are not simply converse equivalents, or time-reversed duals of each other. All light energy may be reflected, but not all unique veillance flux may be reflected!

Paper that first introduced measuring veillance flux and vixels:

Extramission theory: Dormant for 900 years.
Image at left (illustration by Ibn al-Haytham, 11th century), shows the extramissive theory of light, as advocated by Plato and Ptolemy, which theorized that light consisted of rays emitted by the eyes. We now know this theory to be incorrect, on its own. However, in this new work, we now propose an optical theory of the sensitivity to light that propagates out of the eyes, and out from a camera. We have made a new extramissive theory of sensitivity-to-light, by mathematically accounting for the creation, degeneration and absorption of the ability-to-see as it propagates through space.

Difference between Veillametrics and Abakography:

Abakography is taking a long-exposure photograph of lights moved around in space, to make artistic patterns. Abakography was used by Steve Mann to make computerized sequences of flashing light patterns to make artwork.

Veillametrics is measuring what a camera/eye sees. ( Ryan Janzen introduced veillametrics in the first paper [1], and later we've brought it into augmented-reality in [3] and eye-tests in [2].

When you combine it with abakography, you get veillametric-abakography, which is another way to visualize veillametrics. A veillametric bugsweeper can be moved around and photographed.

The veillance field "emitted" by cameras was first proposed and measured here:

The discovery of the veillance field and veillance flux was applied to human-eye "bio-veillametrics" (as measured by a computer system), in the following paper. This very short paper includes some nicer diagrams of the properties of veillance flux:
