MEMS based dual-axes confocal clinical endoscope for real time in vivo imaging
We demonstrate a dual-axes confocal endoscope in a 5.5 mm diameter package for clinical use. Miniaturization is achieved by using a barbell-shaped, gimbaled, two-dimensional MEMS scanner that is actuated by self-aligned, vertical-comb actuators. The maximum DC optical scan angles are plusmn2.6deg on the inner axis and plusmn0.8deg on the outer axis, and the corresponding resonance frequencies are 3.1 kHz and 1.1 KHz. The maximum imaging rate is 10 frames/second, and the microscope achieves full-width-half-maximum transverse and axial resolutions of 5 mum and 7 mum, respectively when operated in the near infrared wavelength (785 nm).
