Abstract

In a raster input scanning arrangement, wherein light from an image is directed to a CCD array, positioning the CCD array with respect to the image is a critical step in calibration to producing optimum image quality. High tolerance mounting assemblies are generally used to support the CCD arrays, provided with a variety of adjustment features to compensate for misalignment in the fixture as manufactured.

BALL-IN-CONE CCD MOUNTING ASSEMBLY (Cont'd)

In a raster input scanning arrangement, wherein light from an image is directed to a CCD array, positioning the CCD array with respect to the image is a critical step in calibration to producing optimum image quality. High tolerance mounting assemblies are generally used to support the CCD arrays, provided with a variety of adjustment features to compensate for misalignment in the fixture as manufactured.

In accordance with the proposal, and as illustrated in Figures 1, 2, and 3, a ball-in-cone mounting fixture is provided for mounting CCD array 8. The CCD array 8 is mounted on frame 10, with a center pixel carefully arranged at the center C of the frame. The frame is mounted on a plurality of bosses 12 which extend outwardly from picture frame support 14, which is fixed to ball
16. Ball 16 has a generally spherical mounting surface 18, selected for a radius centering on center C of the CCD array.

Cone housing 20 is provided with an interior surface 22, complementary to mounting surface 18. Cone housing 20 is supported on housing support 24 having a generally L-shaped cross section. As shown particularly in Figure 3, housing su ort 24 is a...
