Adaptive Optics Scanning Laser Ophthalmoscopy provides highest resolution possible for retinal imaging. The high resolution made it possible for in-vivo single cell imaging. Such high resolution also offers great potential for early disease diagnosis. The picture below shows the before (left) and...

See Yang Lu's Curriculum Vitae Dr. Yang Lu is currently working as a post-doctoral research fellow at the Beetham Eye Institute, Joslin Diabetes Center/ Harvard Medical School. His research focuses on the investigation of diabetic retinopathy using ultrahigh resolution human retinal imaging...

Aplanatic solid immersion lens (SIL) microscopy is required to achieve the highest possible resolution for next generation silicon IC backside inspection and failure analysis. However, aplanatic SILs are susceptible to spherical aberration introduced by substrate thickness mismatch. We have...

A reflective microelectromechanical mirror array was used to control the intensity distribution of a coherent beam that was propagated through a strongly scattering medium. The controller modulated phase spatially in a plane upstream of the scattering medium and monitored intensity spatially in a...

DMs at fixed locations in an optical microscope imaging system was used to provide 2.5x zoom capability, dynamic focus control, and aberration compensation. Zoom is achieved by simultaneously adjusting focal lengths of the two DMs, which are inserted between an infinity-corrected microscope...

a). Deformable mirror open loop control: I characterize the errors associated with open-loop control of a MEMS deformable mirror using an approach that combines sparse calibration of the electrostatic actuator state space with an elastic plate model of the mirror facesheet. The sources of...
