摘要： An encoder in which a light beam emitted from a semiconductor laser or the like is applied to a diffraction grating from a predetermined direction which is not contained in a reference plane defined by direction of relative movement of the diffraction grating and a direction normal to the diffraction grating. A diffracted light created from the diffraction grating by the application of the light beam by the light applying means is reflected by re-entering means and the reflected light is caused to re-enter the diffraction grating at substantially the same position as the position at which the diffracted light is created. At this time, an interference light formed by the other re-diffracted lights than O-order light created from the diffraction grating substantially in the same direction as the predetermined direction by the re-entrance of the diffracted light by the re-entering means is detected, and the information of the relative displacement of the light beam and the diffraction grating is obtained from a variation in the intensity of the interference light.

摘要： A method for detecting a state of rotation of a rotary scale having a diffraction grating therein in which a radiation beam is directed to a first place on the diffraction grating to generate first and second diffracted beams. The first and second diffracted beams are re-diffracted at the first place to form a first re-diffracted beam and a second re-diffracted beam. The first and second re-diffracted beams are directed to a second place on the diffraction grating substantially opposite the first place with respect to the center of rotation of the rotary scale. The first and second re-diffracted beams are diffracted at the second place to interfere with each other so that an interference beam is formed. The interference beam is converted into a signal to detect the state of rotation of the rotary scale.

摘要： An encoder having a long length measuring stroke with a simple construction is provided. The encoder comprises a scale formed with a periodic lattice pattern, first and second reading heads arranged along a moving direction of the scale for reading the scale, and an adder for adding output signals from the first and second reading heads. The encoder further has adjusting mechanism for adjusting such that the phase difference between the output signals from the first and second reading head becomes zero. A continuous periodic signal can be always accurately obtained independently of the position of the scale.
