An infrared detector is protected from thermal background radiation outside its optical field of view.

One of the three states is connected to the other two by the two optical fields.

An optical singularity is a zero of an optical field.

The angle of the initially nonlinear optical field can be non-orthogonal to the surface.

Any dissimilarity between the optical fields will decrease the visibility from the ideal.

In this sense, the visibility is a measure of the coherence between two optical fields.

Most of the canvas remains blank, an empty optical field.

As shown in the picture on the right, an optical field approaches the lens and then it is focused.

The particle's orientation with the optical electric field may also help determine the impedance.

Assuming you've got healthy vision in both eyes, your optical fields overlap.
