A position variation detecting section (103) detects a position variation.

A position variation integrating section (104) integrates the position variation detected by the position variation detecting section (103) to determine and hold the position variation integrated value.

A positional variation computing section (61) computes a positional variation in time series of the specified measurement image region in each cross-section position.

The position variation of the interception point on the sensor is used for measuring the position variation relative to the optical plane of the surface point on which it is positioned.

The detection means generates a signal according to a shift in position of the carriage.

If a long acquisition is performed along a strip across the die in the Y direction, then variation in the acquired spectrum resulting from position variation will primarily depend on the X position of the spot.

Relative positional variation between the belly side member (25) and the backside member (27) is reduced by that friction.

The variation of the posture of the light reflector and the variation of the distances between the light reflector and the open ends of the optical fibers can be reduced to a very small level.

It is not recognized as a change in position, and does not affect the gross external debt position.

The resonant frequency is a function of the physical layout, which is designed such that the frequency variation is less than 150ppm for a variation in edge position of the resonator shape edges of 50nm.

The radiating characteristic of this light reflector unit is determined by changing the position of the light with respect to the reflector unit.

A movement information computing section (62) computes movement information on the biomedical tissue from the positional variation of the computed measurement image region in each cross-section position.

A first adjustment value is selected from among first adjustment candidate values by using a first position variation inspection pattern.

Stimuli are of a mechanical nature: vibration, elongation, tension, variation of position, and linear and angular acceleration.

one combination spin: no flying entry or variations of positions; change of foot optional
