Testing convex hyperbolic mirrors with two or more annuluses by Hindle and stitching methods

Abstract

Based on our previously proposed convex hyperbolic mirrors testing method, we extend the application of this method to test the convex hyperbolic mirrors with two or more annuluses. First, the data deduction for this method is developed. The correspondence of overlapping point pairs is determined by the vertex of the hyperbolic mirror coordinate in image coordinate. Then the misalignment errors in different subapertures are compensated and the subapertures are stitched efficiently. Second, the experimental setup for testing of convex hyperbolic mirror with two annuluses is developed. We present an experiment to verify the validity of this testing method. A convex hyperbolic mirror is tested and stitched with two annuluses and 20 subapertures.
