An improved camera for recording stimuli received by the pilot of an aircraft. The camera features an improved mount for alignment of a charge-coupled device image forming element with respect to the hous­ing of the camera. The improved mount comprises inner and outer eccentric adjustment members fitting within a bore in the camera housing. Each adjustment member comprises a cylindrical outer surface and a cylindri­cal bore, the axes of the cylindrical bores and cylin­drical outer surfaces being parallel to but not coin­cident with one another, such that axial misalignment of an image forming element mounted on the inner adjustment member may be corrected by relative rota­tion of the adjustment members. Skew adjustment may also be provided.
During assembly, the camera according to the invention is mounted on an alignment fixture bearing a predetermined relation to a target. A video image of the target provided by the image-forming element is displayed on a cathode ray tube display device for comparison to a reference image. The inner and outer adjustment members are rotated until the images are aligned, and are then locked. The aircraft contains a camera mount which is in fixed predetermined relation to an object which is to be imaged precisely.
