Abstract:
1. A system for investigating a glazing panel, the system comprising: a hand-holdable housing having a distal end and a wall defining an internal dark space chamber; an electronic infra-red image capture device supported within said housing and facing said dark space chamber; a compressible light seal provided at said distal end of said housing to enable the housing to be held against the glazing panel in a region of a target zone to be investigated; an annular array of infra-red light emitters positioned at said distal end of said housing peripherally about said dark space chamber, wherein said wall is disposed between said annular array of infra-red light emitters and said infra-red image capture device; a processor to process data related to captured image data from the electronic infra-red image capture device; and an output device in communication with the processor and adapted to produce an output related to a condition of the glazing panel at the target zone.
