multidither coherent adaptive optical techniques

[′məl·tē‚dith·ər kō′hir·ənt ə′dap·tiv ′äp·ti·kəl tek‚nēks]
(optics)
Adaptive optical techniques for concentrating laser radiation into as small an area as possible, involving an array of laser sources, one of which has fixed phase, while the phase of a second element is controlled by a low-amplitude phase modulation or dither, and adjusted to maximize the reflection from a target glint. Abbreviated multidither COAT.
