Abstract

The condition of a glazing panel is investigated using a viewing device to view an illuminating electromagnetic radiation profile at a target zone. Data relating to the viewed radiation profile is compared to datum data, to produce an output related to the condition of the glazing panel at the target zone.

Claims

1. An investigation method for investigating the condition of a glazing panel, the method comprising:

using a viewing device to view an illuminating electromagnetic radiation profile at a target zone of the glazing panel, wherein data relating to the viewed radiation profile is compared to datum or data, to produce an output related to the condition of the glazing panel at the target zone.

2. An investigation method according to claim 1, wherein:

data relating to the viewed radiation profile is compared to system stored data.

3. An investigation method according to claim 2, wherein:

the stored data relates to a viewed radiation profile for a non flawed glazing panel viewed zone.

4. An investigation method according to claim 1, wherein:

a readable output is given relating to the condition of the glazing panel.

5. An investigation method according to claim 1, wherein:

the viewing device comprises an image capture device.

6. An investigation method according to claim 1, wherein:

the electromagnetic radiation profile viewed is light.

7. An investigation method according to claim 1, wherein:

the electromagnetic radiation viewed is in the non-visible region of the spectrum.

8. An investigation method according to claim 6, wherein:

the electromagnetic radiation viewed is in the infra red region of the spectrum.

9. An investigation method according to claim 1, wherein:

electromagnetic radiation is directed into the glazing panel in order to facilitate viewing of the radiation profile.

10. A method according to claim 1, wherein:

the target zone is viewed by the apparatus before and after repair and an output generated to quantify or gauge the quality of the repair.

11. A method according to claim 1, wherein:

a backing is positioned opposed to the viewing apparatus adjacent a reverse face of the glazing panel, in order to enhance the viewing process.
