摘要

A wall surface observation apparatus can easily evaluate a wall surface condition and can observe highly accurately concavo-convexities on the wall surface. In particular, the wall observation surface can easily recognize the size and depth of a damage position of a furnace wall of a coke oven chamber. More concretely, the wall surface observation apparatus includes a light source (8a) for emitting a laser beam P1 inclined (Ae) to a y axis and forming a spot (S1/S1a) on an observation surface; a linear image camera 5a for imaging the spot, having a linear visual field 11 extending in z direction; a motor (6a) for driving and rotating the light source and the camera round the z axis; and mirror surfaces 9L1, 9R1 for reflecting the laser beam P1 to the observation surfaces LW, RW and reflecting the laser spot (S1/S1a) on the observation surface to the camera 5a, provided on the support table (SP1 to SP3, 1, 2) in front of the camera in the y direction.
