Abstract This invention shows a mounting for an image sensor in an optical path wherein the axis of the path is perpendicular to the surface of the image sensor so that every pixel on the image sensor is rigidly positioned with respect to the direction of the optical path but is free to undergo small dithering movement transverse to the direction of the optical path. The mounting comprises a platform (64) to which the image sensor is mounted, and at least three wire legs (84) having sufficient rigidity that they support the image sensor without stretching or buckling, each wire leg being attached to the platform at one end and attached to a base plate at the other end. The wire legs are disposed substantially parallel to the optical path so that the platform and the image sensor are movable transversely of the optical path upon the application of a transverse force to the platform without movement along the direction of the optical path.
A means for mounting an image sensor in an optical path, the axis of said path being perpendicular to the surface of said image sensor, such that every pixel on the image sensor is rigidly positioned with respect to the direction of the optical path but is free to undergo small displacements transverse to the direction of the optical path, comprising: a platform to which the image sensor is mounted, and at least three wire legs having sufficient rigidity that they support said image sensor without stretching or buckling, each wire leg being attached to said platform at one end and attached to a stationary base plate at the other end, said wire legs being disposed substantially parallel to the optical path whereby said platform and said image sensor are movable transversely of the optical path upon the application of a transverse force to said platform by slightly bending said wire legs without movement along the direction of the optical path.
