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.
Claims15
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, wherein said source beam is multi-spectral and capable of radiating at different and selectable wavelengths;
- an optical surface coupled to said electromagnetic beam source;
- 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;
- and
- a photoelectric transducer coupled to said sighting portion, said photoelectric transducer facilitates generating an image of a reflected beam.
