摘要
A miniaturized optical bioprobe package is developed using a 3-D micromirror and is tested for bio-imaging application. A silicon optical bench is designed and micromachined to assemble the fiber, lens, and the 3-D micromirror device. A 45 degrees angle trench is used to place the micromirror to achieve larger scanning range. Trace lines are formed on the optical bench and are connected to silicon micromirror using solder. A GRIN lens with lower numerical aperture has been used to focus the optical beam onto the micromirror. The bioprobe is packaged and is tested in a time domain optical coherence tomography (OCT) setup and optical image is obtained for plant tissue.
