Abstract: A laser light adjusting method includes detecting a pair of mode hops and a comparison saturated absorption line group of the pair of mode hops based on an intensity of a light output signal in response to a change applied to an actuator, comparing a mode center voltage value with a comparison voltage value which is the voltage value at which the comparison saturated absorption line group was generated; a control temperature adjustment process that increases a control temperature when the comparison voltage value is lower than the mode center voltage value, and that decreases the control temperature of the temperature adjuster when the comparison voltage value is greater than the mode center voltage value; and a laser light stabilization step that stabilizes an emission frequency of the laser light to a specific saturated absorption line after the control temperature adjustment process.

Abstract: An orthogonal state measuring device includes a measurement table and a CCD camera displacing in X, Y, and Z directions relative to the measurement table and measuring a work piece placed on the measurement table. The orthogonal state measuring device further includes a wide angle surveillance camera, a computer main body, and a display. The wide angle surveillance camera captures in one pass an image that is capable of configuring a bird's-eye image of the work piece, the bird's-eye image encompassing an entire field over which the CCD camera is capable of relative displacement. The computer main body generates the bird's-eye image based on the image and defines a position of the CCD camera on the bird's-eye image, then configures navigation maps in which the position of the CCD camera is composited on the bird's-eye image. The display displays the navigation maps.

Abstract: The present invention relates to an image measurement apparatus images an object to be measured, and measures dimensions and shape of the object to be measured based on an image of the object to be measured displayed on the touch-sensitive panel display. The apparatus comprising: an controller that identifies a command corresponding to a gesture contact-input with respect to the touch-sensitive panel display from a signal output from the touch-sensitive panel display in response to the gesture, and executes the command with respect to a part in the image measurement apparatus, the part being the target of the execution of such command. The gesture is a gesture performed in the state in which the simultaneous touch is made at two or more points.

Abstract: A spatial accuracy correction apparatus performs a spatial accuracy correction of a positioner displacing a displacer to a predetermined set of spatial coordinates using a measurable length value measured by an interferometer and a measurable value of the set of spatial coordinates of the displacement body that is measured by the positioner. The measured length value and the measured value for each measurement point are acquired by displacing the displacement body to a plurality of measurement points in order, one or more repeated measurements are conducted for at least one of the plurality of measurement points being measured after conducting measurement of the measured length value and the measured value for each of the plurality of measurement points, and the plurality of points are measured again when a repeat error of the measured length value is equal to or greater than a threshold value.

Abstract: A compact coordinate measuring machine (CMM) probe configuration is provided for integrating complex circuits into a CMM probe. The CMM probe configuration includes a stylus position detection portion, a stylus suspension portion and a circuit board assembly. The stylus position detection portion includes an alignment frame and an optical sensing configuration. The circuit board assembly includes a rigid-flex circuit element and a three-dimensional carrier frame. The rigid-flex circuit element includes a set of board portions joined by a set of flexible bend portions. The rigid-flex circuit element is folded at the bend portions to locate some of the board portions to be proximate to and/or joined to corresponding support surfaces on the carrier frame. The circuit board assembly at least partially surrounds a majority of the stylus position detection portion and is joined thereto with the carrier frame fixed relative to the alignment frame.
