ABSTRACT:
A symmetrical prismatic readout apparatus includes a pair of substantially identical prism elements positioned in back-to-back relationship with respect to each other to provide a symmetrical structure. The prism elements are bonded together through optical bonding, without the use of adhesives. The two prism elements are similarly bonded to a substrate element, again by optical bonding, without the use of adhesives. Suitable beam splitter arrangements are provided to effect the desired readouts.
