ABSTRACT:
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.
