• A novel probing technique for nano-CMM (Coordinate Measuring Machine) is suggested. In this technique, a micro sphere is trapped optically at the tip of the tapered shape of a single optical fiber and used for a touch probe for the nano-CMM. In order to use the trapped micro sphere for the touch probe, intensity changes of the reentered light that is reflected from the surface of the micro sphere and object are used for the probe signal. When the probe is in contact with the surface of the object, the probe position is decentered from the tip of the optical fiber and the intensity of reentered light is changed. In experiments, the intensity changes are detected by a power meter and applied to be used as the probe signal. Finally, basic properties of the fiber optical trapping probe are investigated and fundamental geometries of samples are also measured.
