Large-Stroke Deformable MEMS Mirror For Optical Focus Control
Thursday, October 24th at 10:10 am in EPS Room 127
Faculty and students are invited to attend
Abstract- We developed a novel large-stroke deformable mirror for focus control and spherical aberration correction. The mirrors fabricated using MEMS technology provide full range (150-200 µm in tissue) of focus scanning at high numerical aperture (N.A=0.5-0.7) for confocal microscopy and optical coherence tomography (OCT). In addition to large stroke, low power consumption and high speed operation are other key factors of the developed devices. The impact of this project is broad since the miniaturized deformable mirrors have a wide range of applications. In addition to focus scanning in microscopes they can also be used in small form factor systems such as cell phone cameras and robot vision. Furthermore the laser based microscopes equipped with the focus control mirror may be useful for skin cancer diagnose and treatment.
