Method and system for measuring the thickness of ice on a surface, notably of an aircraft, using a luminous pattern generated by diffusion in the ice |
摘要 |
A system and method for providing an estimate of the thickness of the ice regardless of the shape of its surface at the level of the air/ice interface. To this end the system and method measure an intensity profile of a luminous pattern generated by diffusion in the ice, which enables the system to measure the thickness of the ice even when the air/ice surface is not plane. |

1. A system for measuring a thickness of ice on a surface of an aircraft, the system comprising:
a light source configured to project a collimated beam onto the surface to generate a luminous pattern by diffusion in the ice; an imaging device configured to acquire an image of the ice including the luminous pattern; a measuring unit configured to measure on the image a luminous intensity profile of the luminous pattern, wherein the luminous intensity profile comprises a curve representing intensity of the luminous pattern as a function of a distance from a point of penetration of the collimated beam into the ice, and wherein the light source is oriented with respect to the surface so that the luminous intensity profile has a summit at the point of penetration; and a calculation unit configured to estimate the thickness of ice present on the surface as a function of the luminous intensity profile, wherein the measuring unit is configured to measure a width of the summit of the intensity profile and the calculation unit is configured to estimate the thickness of ice as a function of the width of the summit of the intensity profile and from at least one predetermined table. |
