Publication number: 20240126069Abstract: An actuator includes a mirror and an electromagnet. The mirror is provided with a permanent magnet and is capable of oscillating about a first axis and a second axis as oscillation axes with respect to a reference plane. The second axis is non-parallel to the first axis. The electromagnet has a yoke and a coil and applies a magnetic flux to the permanent magnet. Both ends of the yoke face each other at least partially across a gap. When viewed from a direction perpendicular to the reference plane, a center Cg of the gap does not overlap a center Cm of the permanent magnet. A current I1 for causing the mirror to oscillate with respect to the first axis and a current I2 for causing the mirror to oscillate with respect to the second axis are superimposed and flowed through the coil.Type: ApplicationFiled: March 1, 2022Publication date: April 18, 2024Inventors: Seiro OSHIMA, Tomotaka YABE, Shingo IWASAKI
