Publication number: 20100097572Abstract: A deforming method for a deformable mirror having plural electrodes and a reflective membrane which are distorted by static voltages. The Zernike voltage template used to deform a deformable mirror is adapted for aberration correction by calibrating each component template according to the specificity of the mirror. The voltages applied to the electrodes to form a surface profile of the reflective membrane are measured based on the reflection light from the membrane. A certain number of voltage-by-electrode patterns each of which corresponds to a different reference profile of the reflective membrane and specifies each set of a voltage and an electrode to which the voltage is to be applied are stored preliminarily. The reflective membrane is deformed to a desired profile by superposing preliminarily stored voltage-by-electrode patterns. The deformation of the mirror is corrected by calibrating each template according to the operational environment.Type: ApplicationFiled: July 7, 2009Publication date: April 22, 2010Inventors: Michiko Nakanishi, Hiroyuki Kawashima, Noriko Saito
