摘要： When an incident light is obliquely incident on an index scale, the optical path length of light A becomes longer than the optical path length of light B and an optical path length difference occurs, which causes a phase difference in both of the diffracted lights incident on a photodetection element. According to the phase difference, intensity of a photoelectric detection signal output from the photodetection element changes. That is, due to a periodic change in the incident angle of the incident light, the phase difference between light A and light B is modulated, and the interference signal becomes greatly modulated.

摘要： An illumination light to be used for position measurement of a movable scale is spatially (or physically) split into a first illumination light and a second illumination light using a triangle prism, and the first and second illumination lights are made to be incident on the same position on the movable scale, so that positional information of the movable scale is detected by utilizing interference of the first and second illumination lights. The spatially split first and second illumination lights interfere with each other even when they are made to be incident on the same position of the movable scale and are completely overlapped with each other, which is different, for example, from the case of the ±1st order diffracted lights that are generated by an illumination light being ±1st order diffracted by a diffraction grating. Therefore, wasted illumination lights that do not contribute to the interference can be minimized and the use efficiency of illumination lights can be improved.

摘要： A reflection mirror that causes an illumination light to be incident on a movable scale is oscillated in an X-axis direction based on a modulation signal. Accordingly, the optical path of the illumination light, of the illumination light and another illumination light generated at an index scale, periodically changes, and as a consequence, the illumination light is periodically modulated. Accordingly, an extra scanner that scans the illumination light or another illumination light with respect to the movable scale does not have to be arranged, which allows an apparatus to be reduced in size and cost.

摘要： A light via first and second index scales is split by a beam splitter, and one of the split lights is received by a first light-receiving element via a movable scale and also the other of the split lights is received by a second light-receiving element via a reference scale, and therefore by computing positional information of the movable scale using an output of the first light-receiving element (a first output) and an output of the second light-receiving element (a second output), movement information of the movable scale can be measured with high precision without being affected by drift of the modulation center (the oscillation center) of the beam.

摘要： A moving grating is arranged on a side of a wafer stage, a light source irradiates a light to the moving grating, diffracted lights generated from the moving grating are interfered by fixed scales and an index scale of which positional relation with the light source is fixed, and a detection instrument detects the interfered light. In this case, since the moving grating is arranged on a side of the wafer stage, upsizing of the entire wafer stage can be suppressed. Further, since interference occurs between a plurality of diffracted lights (e.g., the ±1st-order diffracted light) passing extremely close optical paths, influence caused by a fluctuation of ambient atmosphere becomes less in comparison to conventional interferometers, and thus, a high-precision measurement of positional information of the movable body is possible.
