20100060906 | Means for Measuring a Working Machine's Structural Deviation from Five Reference Axes - Means for measuring a working machine's structural deviation from five reference axes includes a main sensing body bonded with a main axis of the working machine (or controlled to revolve), and a lighting unit set around the main sensing body to circle about the main sensing body with a fixed radius (or the lighting unit radiates a light on the main sensing body from that radial distance and circles along with the main sensing body) such that as soon as the main sensing body has detected an optical signal, it is converted to an error signal informing of the working machine's structural deviation in two or three dimensional displacement. | 03-11-2010 |
20110102778 | Geometric Error Measuring Device - A geometric error measuring device includes a measuring module and at least one (quadrant) photodiode. The measuring module has an emitting deice, which may emit at least one light ray; the photodiode may receive the incident ray. Also, the trajectory of the incident ray is parallel with the direction of measurement. If there is no geometric error, the position of the incident light ray will coincide with the position of the measured light ray. If there is a geometric error, the position of the measured light ray will not coincide with the position of the incident light ray. After the data are processed and calculated, geometric errors in straightness, squareness and rotational angles (pitch, yaw and roll) may be obtained. These geometric errors may then be corrected in the setup of a machine. | 05-05-2011 |
20110261348 | Optical Calibration and Testing Device for Machine Tools - An optical calibration and testing device for machine tools includes a light source unit, a beam splitter, and at least one photo detector.

If there is no tested error, the position of the testing light spot coincides with that of the initial light spot. If there is an error, the position of testing light spot varies according to the error. | 10-27-2011 |
