ABSTRACT:
A displacement sensor is provided with: a light-projection unit; a light-receiving unit having a light-shielding mask and a light-receiving element; a first light-converging element which converges luminous fluxes released from the light-projection unit on a measuring object; a second light-converging element which converges reflected luminous fluxes on the light-receiving unit; a first light-path control element which allows a projection-light light axis and a receiving-light light axis to be coaxially set on the measuring object side; and a light-path length sweeping mechanism which continuously changes a light-path length from the light-projection unit to the measuring object and a light-path length from the measuring object to the light-receiving unit.
