Abstract
An alignment device includes an incoherent light source, a first convex lens, a mirror rod, and a second convex lens. The incoherent light source emits incoherent light that is received by the first convex lens that produces a low divergence light beam. The low divergence light beam is directed to the mirror rod that reflects the light beam to the second convex lens that focuses the light beam to a convergent light beam.
Claims23
An alignment device for use in the alignment of a subject, the alignment device comprising:
- an incoherent light source, wherein the incoherent light source is a multi-color light source that emits incoherent light;
- a first convex cylindrical lens that receives the incoherent light and collimates the incoherent light to produce a low divergence light beam;
- a mirror rod, wherein the low divergence light beam is directed to and reflected off of the mirror rod, wherein the mirror rod demagnifies and diverges the low divergence light beam;
- a second convex cylindrical lens that receives the divergent and demagnified light beam from the mirror rod and focuses the divergent and demagnified light beam to a convergent light beam directed at the subject;
- and
- a controller coupled to the incoherent light source, the controller operating the incoherent light source to produce incoherent light of a selected wavelength.
An alignment device for use in the alignment of a subject, the alignment device comprising:
- an array of incoherent light sources, the array selectively producing a plurality of wavelengths of incoherent light;
- a first convex cylindrical lens that receives incoherent light from the array and collimates the incoherent light to produce a low divergence light beam;
- a mirror rod, wherein the low divergence light beam is directed to and reflected off of the mirror rod, wherein the mirror rod demagnifies and diverges the low divergence light beam;
- and
- a second convex cylindrical lens that receives the divergent and demagnified light beam from the mirror rod and focuses the divergent and demagnified light beam to a convergent light beam directed at the subject.
An alignment turret projecting an alignment beam on a subject, the alignment turret comprising:
- at least one incoherent light source that emits incoherent light of a selectively variable wavelength;
- a first optical system including a first cylindrical lens, a first steering mirror, and a second cylindrical lens, the first optical system receiving incoherent light from the at least one incoherent light source through the first cylindrical lens and projecting a convergent and demagnified first alignment beam at the subject;
- a second optical system including a third cylindrical lens, a second steering mirror, and a fourth cylindrical lens, the second optical system receiving incoherent light from the at least one incoherent light source through the third cylindrical lens and producing a convergent and demagnified second alignment beam at the subject and orthogonal to the first alignment beam.
