Null test for a highly paraboloidal mirror.
نویسندگان
چکیده
A circular null computer-generated hologram (CGH) was used to test a highly paraboloidal mirror (diameter, 90 mm; f number, 0.76). To verify the null CGH test a classic autocollimation test with a flat mirror was performed. Comparing the results, we show that the results of the null CGH test show good agreement with results of the autocollimation test.

Measurement of Highly Parabolic Mirror using Computer Generated Hologram
For evaluating the surface of parabolic mirror (90 mm, F/0.76), two different null test have been discussed. After designing, encoding, and fabricating the CGH(computer generated hologram), the null CGH test was performed. An autocollimation test with a flat mirror was also performed and these testing result were compared
متن کاملA NEW 500 m2 PARABOLOIDAL DISH SOLAR CONCENTRATOR
The Australian National University (ANU) has worked for many years on paraboloidal dish solar concentrators and demonstrated a 400m2 system in 1994. The commercialization of this technology has involved a re-design of the Big Dish concept for mass production. The new design is a 494 m2 concentrator with 13.4 m focal length and altitude-azimuth tracking. It uses 380 identical spherical 1.17m × 1...
متن کاملA Distortion-minimizing Micro-mirror Array with Microactuators for Wide-angle Viewing
Mirrors of numerous shapes, including spherical and paraboloidal mirrors, have been employed for many different commercial and industrial uses, despite their tendencies to distort and warp images. When the object in consideration is planar and oriented normal to the optical axis of the mirror, the amount of distortion introduced by a paraboloidal mirror is less than the distortion introduced by...
متن کاملTime-multiplexed-plasma-etching of High Numerical Aperture Paraboloidal Micromirror Arrays
This paper presents a time-multiplexed plasma-etching method for high numerical aperture paraboloidal micromirrors. By designing the appropriate opening and spacing of etching windows, one can fabricate micromirror arrays with varying focal lengths within one batch. INTRODUCTION Curved micromirrors, including various existing deformable micromirrors, e.g. [1-3], have many applications in micro-...
متن کاملDesign considerations for a highly segmented mirror.
Design issues for a 30-m highly segmented mirror are explored, with emphasis on parametric models of simple, inexpensive segments. A mirror with many small segments offers cost savings through quantity production and permits high-order active and adaptive wave-front corrections. For a 30-m f/1.5 paraboloidal mirror made of spherical, hexagonal glass segments, with simple warping harnesses and t...
