Method and system to detect ice accumulation on ice prone surfaces of an aircraft. The method and system sweeps a Light Detection and Ranging (LIDAR) beam across ice prone surfaces to measure the shape of the ice prone surfaces. The change in shape of the ice prone surfaces indicates the presence of

1. An ice detector for use of an aircraft, comprising: a Light Detection and Ranging (LIDAR) device comprising a transmitter and a receiver placed on the aircraft, such that the LIDAR device measures a shape of an aerodynamic surface on the aircraft in a sweeping manner to detect ice formation; wherein:the transmitter transmits a LIDAR beam to the aerodynamic surface such that the LIDAR beam sweeps across the aerodynamic surface,the receiver detects the LIDAR beam after the LIDAR beam has reflected off the aerodynamic surface,the LIDAR device measures variations of a time of flight of the LIDAR beam between the transmitter and the receiver in real time,the LIDAR device uses the variations in the time of flight to measure changes in the a shape of the aerodynamic surface, andthe changes in the shape of the aerodynamic surface are associated with the ice formation on the aerodynamic surface. 2. The ice detector of claim 1, wherein: the LIDAR device is positioned inside a fuselage behind a window in the aircraft,the transmitter transmits the LIDAR beam through the window, andthe receiver detects the LIDAR beam through the window after the LIDAR beam has reflected off the aerodynamic surface outside the fuselage. 3. The ice detector of claim 1, further comprising a flight deck indication system alerting flight crew when the ice detector detects ice. 4. The ice detector of claim 1, wherein the aerodynamic surface is a wing. 5. The ice detector of claim 1, wherein the aerodynamic surface is a tail. 6. The ice detector of claim 1, wherein the aerodynamic surface is an engine inlet. 7. An ice detector for use of an aircraft, comprising: a Light Detection and Ranging (LIDAR) device comprising a transmitter and a receiver placed on two distinct locations on the aircraft, such that the LIDAR device measures a shape of an aerodynamic surface on the aircraft in a sweeping manner to detect ice formation; wherein:the transmitter transmits a LIDAR beam to the aerodynamic surface,the receiver detects the LIDAR beam after the LIDAR beam has reflected off the aerodynamic surface,the LIDAR device measures a time of flight of the LIDAR beam between the transmitter and the receiver and uses the time of flight to measure the shape of the aerodynamic surface, andthe LIDAR device is mounted on two-axis rotation mount so that the sweeping of the LIDAR beam is in two axes and provides a more complete analysis of the ice formation than an ice detector positioned on the aerodynamic surface. 8. A method of detecting ice, comprising: transmitting a Light Detection and Ranging (LIDAR) beam from an aircraft in a sweeping manner onto an aerodynamic surface of the aircraft, so that the LIDAR beam detects an ice formation on the aerodynamic surface;measuring, in real time, variations in a time of flight of the LIDAR beam between a transmitter and a receiver;using the variations to measure changes in a shape of the aerodynamic surface; andassociating the changes in the shape with the ice formation. 9. The method of claim 8, further comprising using the LIDAR beam to monitor functioning of an anti-ice system used to anti-ice the aerodynamic surface. 10. The method of claim 8, further comprising: detecting the ice formation using the LIDAR beam; andactivating an anti-ice system in response to the detecting. 11. The method of claim 8, further comprising: positioning a LIDAR device comprising the transmitter and the receiver inside a fuselage behind a window in the aircraft, wherein:the transmitter transmits the LIDAR beam through the window, andthe receiver detects the LIDAR beam through the window after the LIDAR beam has reflected off the aerodynamic surface outside the fuselage. 12. The method of claim 8, wherein the aerodynamic surface is a wing. 13. The method of claim 8, wherein the aerodynamic surface is a tail. 14. The method of claim 8, wherein the aerodynamic surface is an engine inlet. 15. The method of claim 8, wherein the sweeping of the LIDAR beam provides a more complete analysis of the ice formation than an ice detector positioned on the aerodynamic surface. 16. The method of claim 8, further comprising: alerting flight crew via a flight deck indication when the LIDAR beam detects the ice formation; andthe flight crew turning on an anti-ice system and/or to moving the aircraft out of an icing condition in response to the flight deck indication.
