Abstract
An image transducing apparatus is disclosed. An object to be imaged is located in a fixed object plane. A lens focuses the image of the object upon an imaging plane. A photoelectric transducing array having a plurality of congruent, discrete, spaced-apart transducing elements arranged in an array is located in the imaging plane and provides an electrical signal representative of the light intensity thereon. The photoelectric array is movable on a microstage which is movable in two axis. The microstage is mechanically displaced in a direction parallel to the imaging plane from a first position to a plurality of subsequent positions. The distance from each position to a subsequent position is less than the dimension of a transducing element along the direction of the displacement. The photoelectric array is moved and is stopped at each of the displaced positions where an electrical signal from the photoelectric array is taken. The signals from each of the positions traversed by the photoelectric array is combined to form an electrical representation of the image of the object.
