Abstract
A series of optical elements is used to produce multiple simultaneous adjoining images on a single image plane. A first, intermediate, image is produced using the first telecentric imaging lens. This intermediate image is produced at a plane coincident with an adjustable-size rectangular field stop. The rectangular field stop is mounted in a sub-housing that allows its free rotation. A second telecentric lens collimates the light from the intermediate image. This collimated light is next passed through an optical splitting means, which uses the principal of refraction to separate the light into multiple components. The optical splitting means is mounted in a sub-housing that allows its free rotation. From here, the light next passes through a third and final lens, which produces a second, final, image on a single, planar detection device. The final image consists of a plurality of identical copies of the intermediate image.
