装置。[Scope of claim for utility model registration] Irradiating a light beam from a light source onto an object to be measured,
In the displacement measuring device that non-contactly measures the distance or displacement to the object to be measured, the device is inserted between the light source and the object to be measured, and the an optical extension part that linearly diffuses the light beam so that its cross section is flat; and a light receiving part formed of one semiconductor element that receives the linear light beam reflected by the object to be measured. , the irradiation position y of the light beam on the light receiving section is calculated from each current value i 1 , i 2 detected from a pair of electrodes attached to both ends of the light receiving section and converted into a voltage value, and K a computing unit that outputs a signal of y = K (i 1 - i 2 )/(i 1 + i 2 ), where A displacement measuring device characterized by comprising a correction circuit.
