Abstract: A microscope system includes a microscope body, a camera connected to an observation optical system of the microscope body, and an XY stage on which a slide of an observation object is placed and which is configured to move in an X-axis direction and a Y-axis direction that are orthogonal to each other. The XY stage includes an XY two-dimensional scale plate. The XY two-dimensional scale plate includes a first mark configured to provide X-axis direction axis information and Y-axis direction axis information of the stage, and a second mark which is provided within an observable region of the camera on the same plane as the first mark and which is available for recognizing a position of an XY plane of the first mark in a Z-axis direction at each of a plurality of points by focus detection of the camera.

Abstract: A stage apparatus comprises an incremental scale fixed to a movable unit and having a predetermined length shorter than a distance the movable unit can move in a first direction, a first and a second sensor that are arranged in the first direction with an interval therebetween shorter than the predetermined length, and a detection unit that detects an origin point position set in a movable range of the movable unit. In an origin return, if the movable unit is at a position at which both the first sensor and the second sensor can read the scale, the apparatus moves the movable unit to the origin point position by a predetermined distance, then moves the movable unit at a lower speed until the origin point position is detected.

Abstract: An optical deflection apparatus including a light source; an optical deflector including first and second oscillators and first and second torsion springs, the first torsion spring connecting the first and second oscillators, the second torsion spring being connected to the second oscillator, and the first and second torsion springs sharing a common torsion axis; and a driver that applies a driving force to the optical deflector; and a driving controller that supplies a driving signal to the driver. The driving controller sets a reference frequency on the basis of a resonant frequency of the optical deflector, calculates a target time at which one of the first and second oscillators makes a predetermined deflection angle on the basis of the reference frequency, and supplies such a driving signal that the one of the first and second oscillators passes through a point corresponding to the predetermined deflection angle at the target time.
