Abstract
A method of deriving a dual field fringe pattern from a single wedge plate for collimation testing is presented. The proposed technique uses a wedge plate and a 90° prism retroreflector to form two interference fields. With the two sets of fringes, the technique provides twofold increase in sensitivity and has its own reference. © 1998 Elsevier Science Ltd. All rights reserved.
