LASER POSITIONER FOR X-RADIATOR Russian patent published in 2006 - IPC H05G1/02 

Abstract RU 2289222 C1

FIELD: positioning radiator with respect to object.

SUBSTANCE: newly introduced in proposed positioner are optical wedge installed on laser optical axis for rotation relative to this axis at frequency f ≥ 10 Hz and at distance A from intersection point of X-ray beam and laser axes that equals distance from this point to X-radiator focus; drive for rotating optical wedge; first beam splitter installed on laser optical axis between optical wedge and first butt-end of laser at distance C > A from center of first reflector and at angle β < 45° to laser axis perpendicular to plane formed by laser and X-ray beam axes; second beam splitter made of plexiglas and installed on X-ray beam axis past first reflector at distance B from its center perpendicular to plane formed by X-ray beam and laser axes at angle γ to X-ray beam axis. Distances B and C as well as angles β and γ are interrelated by equations γ = 45° - β and β=c·tg(2β); optical wedge parameters (angle at θ vortex, ray deviation angle δ, and wedge material refractive index) are interrelated by equations δ = θ(n - 1) and δ = α/2, where α is X-radiation angle. This positioner enables estimation of X-rayed object area and also determination of center of this area.

EFFECT: enlarged functional capabilities, facilitated determination of distance from radiator to object.
