Miniaturized OCT system with optimized housing design

An optical probe is developed for imaging in an optical coherence tomography (OCT) system and a 3D micro mirror is used for moving the beam from the soure to the point of interest on the sample. The completed probe uses a dual axis electro-thermal actuated mirror, silicon optical bench (SiOB)-based probe. The silicon optical bench is designed and micro machined to assemble the fiber, lens and the 3D micro mirror device and inserted into a bio-compatible circular housing. A honey combed structure is fabricated to assist in prevent bridging of the solder balls during reflow. A toroidal lens is being use to correct the beam shape caused by the compatible circular housing.
