Abstract
An optical device that may include a sighting portion including an optical axis; an electromagnetic beam source coupled to said sighting portion, electromagnetic beam source facilitates generating a source beam including an axis that is substantially parallel to said optical axis; an optical surface coupled to said electromagnetic beam source; and a frequency filter coupled within said sighting portion.
Claims18
An optical device comprising:
- a sighting portion comprising an optical axis;
- an electromagnetic beam source coupled to said sighting portion, electromagnetic beam source facilitates generating a source beam comprising an axis that is substantially parallel to said optical axis;
- an optical surface coupled to said electromagnetic beam source;
- and
- a frequency filter including a tunable band-pass filter rotatably coupled within said sighting portion that facilitates tuning said frequency filter to a first frequency.

A method of detecting retroreflectors using an optical device, said method comprises:
- generating an electromagnetic source beam that has a first frequency;
- shaping the electromagnetic source beam;
- channeling the shaped electromagnetic source beam towards a retroreflector;
- channeling a reflected shaped electromagnetic beam that is reflected by the retroreflector through a frequency filter including selectively through a tunable band-pass filter;
- and
- displaying the reflected shaped electromagnetic beam.
