Claim 1
Independent Claim
194 words
A laser projection system comprising a laser projector operably connectable to a computer means for controlling the operation of said system, said laser projector comprising a laser beam source for generating a laser light beam, a collimator comprising a focusing lens for focusing said laser light beam to a focal point, a collimating lens for collimating said laser light beam beyond said focal point and a wedge-shaped lens interposed between the focusing lens and collimating lens, said wedge-shaped lens having an aperture for passing said laser light beam therethrough, two scanners for directing said light beam about a light path, and a photo sensor means for receiving light and generating a feedback signal, said photo sensor means mounted to receive light refracted by said wedge-shaped lens, and a plurality of target reflectors, each having a retroreflective material for retroreflecting a light back to its source, wherein said laser light beam is projectable in a predetermined pattern and if the laser light beam is retroreflected back to the laser light source, the retroreflected laser light beam is refracted by said wedge-shaped lens towards said photo sensor for generating a feedback signal for said computer means.
Claim 2
Dependent Claim
194 words
A laser projection system comprising a laser projector operably connectable to a computer means for controlling the operation of said system, said laser projector comprising a laser beam source for generating a laser light beam, a collimator comprising a focusing lens for focusing said laser light beam to a focal point, a collimating lens for collimating said laser light beam beyond said focal point and a wedge-shaped lens interposed between the focusing lens and collimating lens, said wedge-shaped lens having an aperture for passing said laser light beam therethrough, two scanners for directing said light beam about a light path, and a photo sensor means for receiving light and generating a feedback signal, said photo sensor means mounted to receive light refracted by said wedge-shaped lens, and a plurality of target reflectors, each having a retroreflective material for retroreflecting a light back to its source, wherein said laser light beam is projectable in a predetermined pattern and if the laser light beam is retroreflected back to the laser light source, the retroreflected laser light beam is refracted by said wedge-shaped lens towards said photo sensor for generating a feedback signal for said computer means.
Claim 3
Dependent Claim
57 words
A laser projection system as claimed in claim 1 wherein said plurality of target reflectors comprises a plurality of mountable targets removably mountable on a surface and upon striking said mountable targets with said laser beam, said photo sensor generates a feedback signal for each of said mountable targets for establishing spatial coordinates of said mountable targets.
Claim 4
Dependent Claim
62 words
A laser projection system as claimed in claim 2 wherein said plurality of target reflectors further comprises a moveable target for inserting in said light path of said laser beam while projecting an image onto a surface and upon striking said moveable target with said laser beam, said photo sensor generates a feedback signal for projecting only a portion of the image.
Claim 5
Dependent Claim
22 words
A laser projection system as claimed in claim 3 wherein said wedge-shaped lens has a face angle of between 5° and 45°.
Claim 6
Dependent Claim

Claim 7
Independent Claim
76 words
A method of producing a feedback signal, comprising the steps of generating a laser light beam from a laser light beam source, collimating said laser light beam, directing said laser light beam towards an object, reflecting said laser light beam onto a return path towards the laser light source, refracting said laser light beam on said return path towards a photo sensor, said photo sensor responsive to said laser light beam for generating a feedback signal.
Claim 8
Independent Claim
76 words
A method of producing a feedback signal, comprising the steps of generating a laser light beam from a laser light beam source, collimating said laser light beam, directing said laser light beam towards an object, reflecting said laser light beam onto a return path towards the laser light source, refracting said laser light beam on said return path towards a photo sensor, said photo sensor responsive to said laser light beam for generating a feedback signal.
Claim 9
Dependent Claim
32 words
