Abstract
Pseudoscopic, dual-path optical systems employing plane mirror arrangements for cross coupling the optical paths to reverse the left and right perspectives of object space are provided. Advantageously, the cross coupled path arrangements permit the systems to be manufactured inexpensively because low-cost reflective components can be used and assembled with alignment requirements that are significantly relaxed compared with customary requirements found in uncoupled systems utilizing high-cost prisms or mirror arrangements for similar purposes.
