Publication number: 20240168281Abstract: In an aspect of the present invention, a new active optic is provided, namely, a photo-magnetically actuated deformable mirror (PMADM) made of a magnetic composite structure and an optical quality substrate layer. The magnetic layer is composed of Polydimethylsiloxane (PDMS) and powdered ferromagnetic CrO2. A magnet may be used to deform the mirror surface. The powdered CrO2 has a low Curie temperature (preferably around 395 K) which allows changing the magnetization of the magnetic layer using a laser heating source, thus providing control over the deformation. In one embodiment, the structure has an overall dimension of 1.2 inch 1.2 inch 175 ?m with an optical pupil diameter of 8 mm. The PMADM is estimated to deform to a maximum stroke of 8.7731 ?m before failure with a 3 safety factor.Type: ApplicationFiled: March 3, 2022Publication date: May 23, 2024Applicant: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Ewan S.
