A non-contact tool measurement apparatus is used in a machine tool environment. The apparatus includes a transmitter including a first aperture and a laser for generating light that is emitted from the transmitter through the first aperture towards a tool-sensing region. A receiver includes an optical detector and is arranged to receive light from the tool-sensing region. A processor analyses the light detected by the optical detector to enable the measurement of tools in the tool-sensing region. The laser is capable of generating light having a wavelength of less than 590 nm thereby enabling the size of the first aperture to be reduced resulting in a reduction in contaminant ingress. In one embodiment, the laser generates blue light.

A workpiece installation method includes obtaining a reference image that shows a reference workpiece whose posture has been adjusted, setting workpiece reference lines on a boundary of a first image area occupied by the reference workpiece in the reference image, obtaining a measurement image that shows a workpiece, generating, using a processor, a measurement combined image in which workpiece reference lines are superimposed on the measurement image and which shows the workpiece reference lines pass through positions respectively identical to workpiece reference line positions, and adjusting a posture of the workpiece such that a boundary of a second image area occupied by the workpiece in the measurement combined image is shown to be substantially parallel to or substantially coincident with the workpiece reference lines.
