DEFINITION

Classification: 359/338

Using phase conjugation:

(under subclass 337) Subject matter wherein the light beam returns through the medium at precisely the same angles,

distances, and intensities it was directed prior to the reflection.

(1) Note. The medium causes the light to return to its origin after reflection in precisely the same identical path it took to reach the reflector.

(2) Note. See the January 1986 Scientific American article on this subject matter.

(3) Note. This is often used to clear up poor images.
