LASER CONFOCAL TWO-WAVE RETINOTOMOGRAPH WITH FREQUANCY DEVIATION Russian patent published in 2008 - IPC A61B3/00 A61F9/08 A61B3/14 

FIELD: medical equipment.

SUBSTANCE: given device consists of injective laser diode with wave length λ=610 nm, current supply to laser diode excitation, microscope objective forming focused probing laser beam, two micro-diaphragm, one of which is within probing laser beam waist in object plane, and the other one lies within image plane and conjugates with first micro-diaphragm relative to semi-transparent mirror for reflected beam from probed retina focal region, detecting photoreceiver, optical two-dimensional scanner, optical system realigning laser beam focal spot by retina depth. Additionally it comprises auxiliary injective infrared laser diode with wave length λ=810 nm, laser beam of which is coaxial with main laser diode radiation with period less than indication time of one spatial point in scanning retinotomograph and auxiliary photoreceiver selectively detecting radiation at wave length λ=810 nm.

EFFECT: extended diagnostic performance of confocal one-wave laser retinotomograph.
