  • Diode-laser line-illuminating system
    Patent number: 6612719
    Abstract: An illumination apparatus includes a semiconductor laser providing light-output in first and second mutually perpendicular axes. The light-output propagates in a direction mutually perpendicular to the first and second axes. An optical system is arranged cooperative with the semiconductor laser to focus the light-output inn the first and second axes at respectively first and second focal points spaced apart in the propagation direction. At a plane intersecting the first focal point perpendicular to the direction of propagation, the focussed diode-laser light-output is formed into a line of light having a width in the first axis and a length in the second axis.
