Abstract
Interferometer for figure of large convex hyperboloid mirrors contains concentric meniscus lens and wavefront analyzer for study the wavefront reflected from measured hyperbolic mirror. Concentric lens rotates around the imaginary focus of the tested mirror to measure full surface of the hyperbolic mirror. Main advantage of proposed interferometer is the possibility of figuring the shape of extremely large convex hyperbolic mirrors with a diameter more than 2 meter. In addition, the interferometer may be applied for measure the hyperbolic mirrors with a very large aperture angles in the imaginary geometric focus, for example with the aperture angle of 180° or even more.
