Umbrella-Like Dual-Axis Mirror Scanner Fabricated With FDM 3D Printing and Its Application in Realizing a Dynamic FOV Camera

In this paper, we demonstrate a low-cost mirror scanner design of umbrella-like architecture.The primary structures are 3D-printed using PLA (polylactic acid) as the material.A 400 mm2 aluminum–deposited silicon chip is fixed on the mirror frame, which is part of the 3D-printed assembly, and serves as the reflective sword mirror.Miniature permanent magnets are embedded in the mirror frame so that the mirror can then be electromagnetically driven.

Our latest-version scanner reaches optical scan angles Keypad Windows of 7.8 and 7.4 degrees for the x- and y-scans at their resonant frequencies (37 Hz and 49 Hz), respectively.Under DC actuation, a full optical scan range of 10.

1 degrees in the x- direction can be achieved when the voltage is tuned from +12 V (+0.089 A) to −12 V (−0.089 A).Additionally, we will demonstrate its integration with a smart phone camera to achieve a dynamic FOV (field of view).
