This paper presents a Lorentz force FPCB (flexible printed circuit board) mirror based LiDAR. The driving coil and torsion beam are fabricated using low cost commercial FPCB fabrication process. A thin silicon mirror plate coated with aluminum is attached on top of the middle of the FPCB structure. External magnets on both sides and the current through the coil generate Lorentz fore to rotate the FPCB mirror. The oscillating FPCB mirror is combined with a single point LiDAR to achieve a scanning ID LiDAR. The mirror plate steers the emitted laser beam, collects the diffuse reflected light and reflects to the receiver of the single point LiDAR. The achieved performance of the scanning LiDAR is: field of view-60°, 500 points, refreshing 10 kHz, distance 40 meters with an error of 10 cm.
