A system includes an environment for programming workpiece inspection operations for a coordinate measurement machine (CMM). The environment includes a user interface comprising a program simulation portion configured to display a 3D view of the workpiece and/or representations of inspection operations to be performed on the workpiece. The user interface further includes auxiliary collision avoidance volume (CAV) creation elements that create CAVs that are represented in the 3D view. The 3D CAVs and/or their representations have integrated graphical modification properties which are controllable in the user interface. The modification properties are activated by selection of a face of the CAV representation, without the explicit activation of a separate modification control element mode or tool. This results in a simplified and intuitive user interface. Users perform a constrained set graphical modifications in the 3D view using an input device, to modify a CAV.

A method is provided to assist adjustment for a movement path of a probe. A coordinate measuring machine includes a probe having a tip for detecting a surface of an object, and a movement mechanism for moving the probe, and measures a shape of the object by allowing the probe tip to scan the surface. A controller controls operation of the coordinate measuring machine by calculating a scanning path for allowing the probe tip to perform scanning movement and the movement path followed by the probe when the probe tip moves along the scanning path, setting control points on a line connecting each position of the probe tip and each corresponding position of the probe accepting a change in position of the control points by a user, and changing the movement path accordingly. A guide point allows the control points to move collectively.

A telecentric optical apparatus that is capable of suppressing an increase in the number of components as well as achieving high precision optical axis alignment, is provided. The telecentric optical apparatus of the present invention is characterized in that it is provided with: a first telecentric lens surface that is provided on an object side; a second telecentric lens surface that is provided on an image side and that shares a focus position with the first telecentric lens surface; and an optical path trimming part that is provided, between the first telecentric lens surface and the second telecentric lens surface, in an outside region, which is located on a side further out than a light passing region having a center thereof located at the focus position, and that changes an optical path such that a light beam incident on the outside region is prevented from contributing to image formation.

A resistor string outputs sixteen signals with a phase difference of 22.5 by dividing voltage between two adjacent phases of a four-phase input signal with a phase difference of 2/M (where M is an integer equal to or greater than 2), and by generating four signals with a delayed phase for each phase of the four-phase input signal. A switch portion selects four signals with a phase difference of 90 from the sixteen signals. Amplifiers output each of the four signals, which are attenuated by dividing the voltage with the resistor string, as a four-phase output signal by amplifying each of the four signals such that an amplitude of the four signals matches the amplitude of the four-phase input signal.

A distance in a scanning direction between a first set of edges which face each other and exhibit an opposite change between light and dark is measured by an image measuring machine, and a bias correction value is calculated based on a difference between a measured value and a true value. Using the bias correction value, detection point correction values, which are correction values in various directions of edge detection points detected by a scan of a measured object using the image measuring machine, are calculated; a correction amount used in correction of the edge detection points is specified based on the detection point correction value in each direction; and the edge detection points are corrected using the correction amount.

A measuring probe(300) includes a stylus(306), an axial motion mechanism(310), and a rotary motion mechanism(334). The axial motion mechanism(310) includes a pair of first diaphragm structures(314, 315) that allows a moving member(312) to be displaced, and the rotary motion mechanism(334) includes a second diaphragm structure(340) that allows a rotating member(RP) to be displaced. The second diaphragm structure(340) is disposed between the pair of first diaphragm structures(314, 315) in an axial direction(O). The respective first diaphragm structures(314, 315) are disposed at a symmetric distance with respect to the second diaphragm structure(340). This can reduce the length in the axial direction and weight thereof and also reduce shape errors and improve measurement accuracy.

An optical probe includes a first resonant scanner having a first mirror capable of rotating centered around a drive axis, the first resonant scanner reflecting emitted light from a light source toward a measured object, and a second resonant scanner having a second mirror capable of rotating centered around the drive axis, the second resonant scanner reflecting light reflected from the measured object toward a photoreceiver. The first mirror and the second mirror are rotationally driven in synchronization.
