Abstract: A cam face 303a of a cam 303 has a shape depending on the distribution of the light amount in the cross-section of reference light LR. When the cam 303 is rotated by a stepping motor 302, an abutment 312 moves following the displacement of the cam face 302a with the rotation of the cam 303. A light-blocking link 310 rotates about the axis of rotation 311 with the movement of the abutment 312. A shield 313 moves in a first direction with the rotation of the light-blocking link 310 to change the shielding region of the reference light LR. A light-blocking plate 400 can shield the reference light LR from a second direction different from a shielding direction (first direction) by an attenuator 300. The light-blocking plate 400 is moved by a drive mechanism 410 and changes the shielding region.

Abstract: A main controller 211 controls a fiber-end drive mechanism 140 and an attenuator 121 with reference to the received-light amount of interference light LC to cause the following operations (1) and (2) to be executed alternately: (1) moving an emission end 116 to increase the received-light amount to at least an upper limit; and (2) changing the light amount of reference light LR to decrease the received-light amount to at least a lower limit. When the received-light amount specified by an received-light-amount specifying part 212 decreases in response to the movement of the emission end 116 in (1), the main controller 211 controls the fiber-end drive mechanism 140 to return the relative position to the immediately preceding status of this change. The main controller 211 leads the received-light amount of interference light LC by a CCD image sensor 120 to a target value by controlling the attenuator 121 to change the light amount of interference light LC.

Abstract: An optical image measuring device forms an image of an object to be measured based on a result of light-receiving by a light-receiving part. This optical image measuring device comprises: a specifying part configured to specify the light irradiated state to the light-receiving surface of a light-receiving part via a light guiding part and a dispersion part; and an altering part configured to alter the relative position and/or direction between a light-receiving surface and the exit end of light from the light guiding part, based on the light irradiated state.

Abstract: An optical image measuring apparatus capable of speedily starting image measurement in response to a measurement start request and performing image measurement on a region on which focus is achieved at determination of an image region. When observation light (M) is focused on an observation CCD camera (23), measurement CCD cameras (21, 22) are disposed to have a measurement object point (Q) in a position shifted from point (P) to an apparatus side. In response to a measurement start switch (60), an interferometer moving stage (50) is moved to adjust an optical path length difference, thereby shifting the point (Q) to the point (P). The distance (d) is set to equal to or longer than necessary to move the interferometer moving stage (50) which accelerates a moving speed thereof to a predetermined speed. Thereby, image measurement can speedily start in response to request for image measurement of an object (O).
