Definitions
- the present invention relates to a system for defrosting or demisting an optical instrument such as an image acquisition device. It also relates to an image acquisition device equipped with such a defrosting device and / or demister.
- the invention is particularly applicable to a camera equipping an aircraft.
- such a camera makes it possible to precisely visualize the position of the wheels on the track and the possible obstacles when taxiing the plane.
- these cameras are subject to the extreme conditions prevailing outside a plane at altitude flying.
- the temperature outside the plane is around -50 ° C.
- cameras may be exposed depending on the flight phase of the aircraft at temperature ranges from -55 ° C to +70 ° C.
- These cameras typically include an image sensor and a lens that are placed inside a protective case to protect them from ambient, i.e., temperature and humidity conditions.
- the air trapped in this housing may contain a certain amount of water.
- this layer of frost remains on the structure until the outside temperature rises sufficiently to melt.
- a pilot may be deprived of visual access to certain parts of the aircraft because of the mist or frost created by the accumulation of water particles at the level of the protective glass, or porthole , of the camera usually used to visualize these parts.

- heating elements intended to be placed in contact with the thermal conductive film for heating this film, and - A power supply circuit of these heating elements.
- this system therefore advantageously makes it possible to ensure perfect control of the heating of the window while freeing the optical path to the sensor of an acquisition device. Images for example so that the image in acquisition is not partially masked by one or more objects.
- this defogging or deicing system can be implemented on an image acquisition device or an optical observation device.
- the porthole is a lens for example.
- the heating elements are resistors intended to at least partially cover the thermal conductive film, and whose width and length are defined with respect to the transverse dimension and form of the thermal conductive film, As an illustration, the thermal conductive film having an annular shape, the transverse dimension of this film is its width.
- the heating elements are then resistors of small dimensions to take into account the annular shape of the conductive film. These small dimensions of the resistors make it possible to increase the surface of contact with the thermal conductive film and consequently, the transmission of the calories.
- this conductive film is a thermally deformable thermal conductive film in order to fit the surfaces of the heating elements
- the film is for example deformable in that exerting a pressure on its external surface, one obtains a compression of the original thickness of this film.
- the heating elements being pressed against this film, the film comes to marry the surface of these heating elements which ensures a better thermal transfer of heat in the film.
- the power supply circuit comprises a printed circuit on which the heating elements are mounted, this printed circuit being intended to supply the heating elements with energy, the printed circuit has an annular shape,
- the printed circuit serving as a support for the heating elements could have any other shape to release at its center the optical path to the sensor of an image acquisition device. it comprises a temperature sensor intended to be placed close to the surface of said porthole and able to generate a temperature signal.
- a temperature sensor intended to be placed close to the surface of said porthole and able to generate a temperature signal.
- near the surface is meant, on the surface or at a distance allowing physical interaction with that surface so that the sensor can measure a temperature that has been calibrated.
- the system comprises another heating element intended to be placed in the housing.
- this other heating element may comprise one or more resistors connected in parallel to reconcile the space requirement and the power to be dissipated.
- the invention also relates to an image acquisition device comprising a protective housing in which at least one sensor is placed, this housing comprising a window placed in front of the sensor.
- the device comprises a demisting or deicing system as described above.
- this image acquisition device may comprise a video camera sensor or digital photography apparatus such as a CDD or CMOS for acquiring the images.
