Abstract:
An eye safety system, based on retro-reflection from the eye, to shut off a laser source in a short time to avoid approaching the hazard level of the eye. In the event of an accidental direction of laser light toward a nearby eye, the system rapidly collects and detects laser light that retroflects from the retina of the eye. Upon detecting the retroflected light, a comparator/processor assembly signals to switch off the laser source to terminate the hazard to the eye.

Claim (Index 13):
A safety system for use with a laser source, the system adapted to protect a user's eye from harm due to laser light directed toward the eye, and comprising:\n at least one primary lens for collimating into a collimated beam a divergent beam emitted from the source; a dichroic beam splitter for splitting the collimated beam, whereby a first portion of the collimated beam passes through the beam splitter and a second, redirected, portion of the collimated beam is reflected from a first side of the beam splitter; a light trap for capturing the redirected portion of the collimated laser beam; at least one secondary lens for expanding and collimating into a main beam the first portion of the collimated beam; a laser light detector; an eye safety lens for directing to the detector a portion of any returning beam reflected from a second side of the beam splitter; and an amplifier and comparator assembly, in communication with the detector, for:\n identifying a retroreflection signal from the detector; and \n switching off the laser source; \n wherein when a returning beam is retroflected from the user's eye, it is directed to and detected by the detector, which detector generates a retroflection signal to the amplifier and comparator assembly to switch off the laser source.
