1. A remote marking system comprising:
- at least one marker unit;
at least one target region; and
at least one concentrator,wherein said marker unit comprises at least one emitter configured to emit at least one low intensity tracer signal,wherein said target region comprises at least one receiving medium configured to change its state upon reception of a high intensity tracer signal thereby recording the position at which said high intensity tracer signal is received,wherein said concentrator is configured to transform a low intensity tracer signal to a high intensity tracer signal, andwherein said marker unit comprises an extended emitter operable to emit a low intensity tracer signal over an extended region and said concentrator is configured to focus said low intensity signal such that it is incident upon a concentrated region of said receiving medium.

12. A remote marking system comprising:
-
at least one marker unit; a plurality of target regions; and at least one concentrator, wherein said marker unit comprises at least one emitter configured to emit at least one low intensity tracer signal, wherein said target region comprises at least one receiving medium configured to change its state upon reception of a high intensity tracer signal thereby recording the position at which said high intensity tracer signal is received, and wherein said concentrator is configured to transform a low intensity tracer signal to a high intensity tracer signal, and each said target region comprises; a first receiving medium selected such that upon reception of said tracer signal, the color of at least a section of said target region turns red; a second receiving medium selected such that upon reception of said tracer signal, the color of at least a section of said target region turns green; a third receiving medium selected such that upon reception of said tracer signal, the color of at least a section of said target region turns blue; and a fourth receiving medium selected such that upon reception of said tracer signal, the color of at least a section of said target region turns black. - View Dependent Claims (13)

14. A remote marking system comprising:
-
at least one marker unit; at least one target region; and at least one concentrator, wherein said marker unit comprises at least one emitter configured to emit at least one low intensity tracer signal, wherein said target region comprises at least one receiving medium configured to change its state upon reception of a high intensity tracer signal thereby recording the position at which said high intensity tracer signal is received, and wherein said concentrator is configured to transform a low intensity tracer signal to a high intensity tracer signal, and further comprising a concentrator configured to increase the intensity of the tracer signal, wherein said concentrator comprises a beam focusing device selected from a group consisting of;
a converging lens, a concave reflector, an array of angled reflectors and combinations thereof.
