LASER LOCALIZER FOR X-RAY EMITTER Russian patent published in 2006 - IPC H05G1/00 

FIELD: technology for orientation of emitter relatively to object.

SUBSTANCE: in focal plane of objective of digital photo-camera, selective light filter is provided additionally, positioned directly within focal plane of objective of digital photo-camera, made of optical material, having low optical density D≤0,1 at wave length of laser emission and high optical density D≥4,0 for all other wave lengths of solar radiation spectrum within range from λ≥0,38 micrometers and to λ≤0,67 micrometers, received by digital photo-camera, light filter is made in form of rectangle, length of which is l≥H, where H - dot matrix size of CCD matrix of digital photo-camera, width t≤0,01H, and thickness is selected from condition l_λ≥D_λ/K_λ, where K_λ - specific coefficient of filter material absorption at this wave length, while light filter is positioned on dot matrix of CCD matrix along the line, connecting images of laser spots on the object.

EFFECT: stable operation of localizer with any lighting mode, especially under conditions of exposure to daylight.
