MULTI-BEAM SCANNER Russian patent published in 2011 - IPC G02B26/10 

FIELD: physics.

SUBSTANCE: proposed device comprises multiple first optical systems each comprising light source to emit uncollimated laser beam and optical element with preset optical force that affects light emitted from light source unit, second optical system comprising first deflector whereon laser beams fall emitted by multiple first optical systems designed to deflect laser beams, common optical system to vary divergence of every laser beam and laser beam shifter. Light beams coming onto first deflector fall, in fact, at one point. Note here that optical axes of optical elements intercross at points spaced apart from optical element by focal distance of optical element.

EFFECT: simplified design, smaller sizes.
