A LiDAR resonator with dynamic force equilibrium that includes a spring fork mechanism having a first tine and a second tine with the same stiffness as the first tine, wherein the spring fork mechanism is configured to resonate at a resonant frequency, an optical module, mounted to the first tine, for transmitting a light pulse and receiving a reflection of the light pulse, a voice coil, also mounted to the first tine, for generating an alternating magnetic field at the resonant frequency, a counterweight, mounted to the second tine, having a mass and CG equal to a mass and CG of the combined optical module and the voice coil, and a signal source for coupling an alternating current signal at the resonant frequency to the voice coil such that the voice coil is operative to generate an alternating magnetic force at the resonant frequency between the voice coil and the counterweight.
