摘要： A velocity detection apparatus detects a position of a moving object at a first timing and a second timing to detect a velocity of the moving object based on a difference between the first timing and the second timing. The first timing is a timing at which an identifiable mark position of the moving object is detected by a first detector and the second timing is a timing at which the mark position is detected by a second detector. The velocity detection apparatus includes a light source and first and second detectors which detects the mark position based on light obtained by illuminating the moving object using the light source. A vertical projection position of the light source onto a plane which is parallel to a main surface of the first or second detector is located between vertical projection positions of the first and the second detector onto the plane.

摘要： A displacement detection apparatus includes a scale 115 on which marks are disposed, first and second position detection sensors 111 and 112 detecting positions of the marks 110, and a processor 409 performing a calculation processing of an output signal from each of the first and second position detection sensors 111 and 112. The first and second position detection sensors 111 and 112 are disposed at a distance L from each other to be movable relative to the scale 115. The processor 409 calculates a correction value P′ of a mark pitch P of the marks 110 using the distance L, a first time TPK required for K marks of the marks 110 to pass a detection position, and a second time TL required for a specific mark of the marks 110, which are measured at the same time of the first time TPK, to move the distance L.
