Abstract

A remote pointing system which permits the remote positioning of a laser beam in accordance with signals received from a laser beam situated at another location. These signals are derived through the use of an appropriate filter, television camera, pair of counters and modem located at the transmitting location and a telephone receiver, modem, microcomputer, pair of analog to digital converters and suitable beam directing means at the remote or receiving location. By interconnecting the above-mentioned elements by way of a telephone line and proper interfacing of electronics, positioning of the remote laser beam can be accurately and reliably accomplished.

Claims

1. A remote pointing system comprising first means situated at a preselected location for emitting a visible beam of radiant energy of preselected wavelength, first means having a preselected configuration located adjacent said first beam emitting means for displaying thereon said visible beam of radiant energy and allowing further transmission of said visible beam of radiant energy, means in optical alignment with said beam of radiant energy transmitted from said first display means for receiving only said preselected wavelength of said beam of radiant energy and transmitting a signal capable of transmission over a telephone line corresponding to the position of said beam of radiant energy on said first display means, said receiving and telephone line transmission signal transmitting means including a video camera in optical alignment with said beam of radiant energy transmitted from said first display means and means operably connected to said video camera for converting a signal emanating from said video camera into said signal capable of transmission over said telephone line, means situated at a location other than said preselected location for receiving said telephone line transmission signal corresponding to the position of said beam of radiant energy on said first display means and transmitting a signal in accordance therewith, second means situated at said other location for emitting a visible beam of radiant energy, second means having a preselected configuration located adjacent said second beam emitting means for displaying said visible beam of radiant energy emitted therefrom, means operably connected to said position signal receiving and transmitting means at said other location for directing said beam of radiation emitted from said second beam emitting means onto said second display means in accordance with said position signal whereby the position of said beam of radiant energy on said second display means corresponds to the position of said beam of radiant energy on said first display means.

2. A remote pointing system as defined in claim 1 wherein said means at said other location for receiving and transmitting said signal corresponding to the position of said beam of radiant energy on said first display means comprises a telephone receiver for receiving said telephone line transmission signal, means operably connected to said telephone receiver for converting said telephone line transmission signal into a digital signal, means operably connected to said means for converting said telephone line transmission signal into said digital signal for processing said digital signal and providing a pair of digital output signals representative of the position of said beam of radiant energy on said first display means and means operably connected to said processing means for converting said pair of digital output signals into a pair of analog output signals for use with said directing means.

3. A remote pointing system as defined in claim 2 further comprising means operably interposed between said video camera and said means for converting a signal into a signal capable of transmission over a telephone line for providing a signal representing the horizontal and a signal representing the vertical position of said beam of radiant energy on said first display means.

4. A remote pointing system as defined in claim 3 wherein said directing means comprises a first adjustable mirror and a second adjustable mirror, means operably connected between said digital to analog converting means and said first and second mirrors for adjusting said mirrors in accordance with the pair of analog output signals.

5. A remote pointing system as defined in claim 4 wherein said receiving and telephone line transmission signal transmitting means further comprises means optically aligned with said first beam of radiant energy transmitted from said first display means and interposed between said first display means and said video camera for allowing only said preselected wavelength of radiation to be received by said video camera.

6. A remote pointing system as defined in claim 5 wherein said video camera is a television camera.

7. A remote pointing system as defined in claim 6 wherein said first and second beam emitting means are both in the form of lasers.

8. A remote pointing system as defined in claim 7 wherein said means for converting a signal into a signal capable of transmission over said telephone line and said means for converting said telephone signal into a digital signal are both modems.

9. A remote pointing system as defined in claim 8 wherein said means for providing horizontal and vertical position signals are a pair of counters.
