Endomicroscopic OCT system based on micromachined tethered silicon oscillator. (a) Fully packaged OCT endomicroscope inside a gastrointestinal endoscope, the endomicroscope with compact packaging passes through the accessory channel. (b) Schematic illustration of a Lissajous fiber scanner mounted inside a quardrapole piezoelectic tube with micromachined silicon structure. (c) Photograph of the fully micro-assembled Lissajous fiber scanner. A 20 mm long fiber cantilever with additional supporting structures was mounted on a PZT tube (Reproduced with permission from OSA [57]).
