ABSTRACT:
A light intercepting device includes a movable portion allowed to swing about a support portion as a torsional axis, a shielding portion provided at an end portion of the movable portion in a direction perpendicular to the torsional axis, a driving wiring provided on the movable portion, and a magnetic field generator to apply a magnetic field to at least a part of the driving wiring in a direction perpendicular to the driving wiring. A position of the shielding portion is changed by power supply control for the driving wiring to control transmission and interception of space light.
