Honey comb structures perforated core bond controlling method, involves lighting up lightened zone on free surface, detecting light reflected from cells in observed zone, and detecting opening in cells in photographed zone
Honey comb structures perforated core bond controlling method, involves lighting up lightened zone on free surface, detecting light reflected from cells in observed zone, and detecting opening in cells in photographed zone
The method involves lighting up a lightened zone (17) on a free surface (4) of honeycomb structure (1) by a light source (15) to illuminate the interior of cells (5) opening in the lightened zone. Emerging light (21) reflected from the cells is detected in an observed zone (22). Opening (6) in the cells (5) is detected in a photographed zone (32) located in front of the observed zone. An independent claim is also included for an instrument for controlling bond of a perforated core of a honeycomb structure.
