Abstract: A non-contact probe includes: a light irradiating section that scans a measurement target object with spot-like laser beam; an image-capturing section that captures an image of the laser beam reflected by the measurement target object by using a plurality of pixel columns selected from a light-reception surface including a plurality of pixel columns, and generates a captured image; a position sensing section that senses an image-formation position of the laser beam on the captured image; and a pixel column changing section that selects a different plurality of pixel columns such that the image-formation position is included in the selected plurality of pixel columns.

Abstract: A coordinate measuring device includes a non-contact-type measurement probe having a light emitter that emits light at a work piece along a plane, and an image capturer that captures an image of the emitted light produced by a surface of the work piece; a determiner that determines whether a distance from the measurement probe to the work piece is in an imageable range where the image of the emitted light can be captured, in a far range that is more distant than the imageable range, or in a proximal range that is closer than the imageable range; a notification device issuing a notification of results of a determination made by the determiner; and a memory storing the determination results.
