ScholarBank@NUS Repository. https://doi.org/10.1364/OL.37.001745 | Abstract: | We report a miniature adjustable multi-blade iris diaphragm driven by microelectromechanical-systems-based electrostatic rotary microactuators. A proof-of-concept device is designed and fabricated using a silicon-on-insulator micromachining process. The diameter of the developed iris diaphragm aperture is experimentally demonstrated to be able to adjust from 0.45 to 1.56 mm. When used in a miniature camera lens system, the current prototype device is capable of providing an adjustment range of more than three full f /stops. © 2012 Optical Society of America. | Source Title: | Optics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/60740 | ISSN: | 01469592 | DOI: | 10.1364/OL.37.001745 |
