Study on Improving Precision of Asphcric Surfaces Test by Computer-generated Hologram
In this paper,the principle of CGH (computer-generated-hologram) phase detecting interferometry is briefly discussed.A new absolute measuring method with CGH for testing high precision aspheric surfaces is presented.The measuring accuracy can be up to λ/50.
