Abstract
Scanning apparatus including a light source for providing at least one light beam, a medium for receiving the light beam and two helical optical apparatuses disposed between the light source and the medium for sequentially receiving the light beam and for directing the light beam towards the medium.
Claims21
Scanning apparatus comprising:
- a light source for providing at least one light beam;
- a medium for receiving said at least one light beam;
- and
- two helical optical means disposed between said light source and said medium for sequentially receiving said at least one light beam and for directing said at least one light beam towards said medium.
1 more element
Scanning apparatus comprising:
- a light source for providing at least one light beam;
- a single helical surface for receiving and reflecting said at least one light beam;
- and
- reflecting means located generally close to said single helical surface for receiving said at least one light beam reflected from a first location on said single helical surface and for reflecting said at least one light beam to a second location on said single helical surface;
- and
- a medium for receiving said at least one light beam reflected from said second location.
3 more elements
A method of scanning a medium including the steps of:
- providing at least one light beam;
- receiving said at least one light beam on a first helical optical means and reflecting and shaping it to a second helical optical means;
- receiving said at least one light beam on said second helical optical means and reflecting and shaping it to said medium;
- and
- repeating said step of providing and both steps of receiving while rotating said first and second helical optical means.
2 more elements
A method of scanning a medium including the steps of:
- providing at least one light beam;
- receiving said at least one light beam on a helical surface and reflecting said at least one light beam reflected from a first location on said helical surface to reflecting means located generally very close to said helical surface;
- reflecting said at least one light beam reflected from said reflecting means to a second location on said helical surface;
- and
- receiving said at least one light beam reflected from said second location on said medium.
