Abstract
A self-supported optical correlator has a first holder having two opposite ends, one of the opposite ends being provided with anchor points, the other end being provided with a light source. The correlator also has a second holder having two opposite ends, one of which is provided with anchor points, the other being provided with a light receiving element, and a plurality of intermediary holders, each having two opposite ends provided with anchor points, at least one of the intermediary holders being provided with a spatial light modulator for projecting an image and another of the intermediary holders being provided with another spatial light modulator for projecting a filter. Each of the intermediary holders is provided with optical components secured within the holders. The said anchor points are adapted to secure the first, second and intermediary holders together linearly end to end; so that when the intermediary holders are assembled end to end, and the first holder is assembled at one extremity and the other holder is assembled at another extremity, the resulting assembly forms said optical correlator. The optical components are toleranced, and the anchor point serve to asse…
