TWO-DIMENSIONAL POSITION MEASUREMENT OF OBJECTS WITH CIRCULAR CROSS-SECTION USING SINGLE LINEAR CCD SENSOR

Tomáš Radil, Jan Fischer
  • Abstract:
    This paper describes a novel method of twodimensional position measurement of objects with circular cross-section. The proposed method employs a single linear CCD sensor and two point light sources. Using this simple measuring set-up the described method achieves typical linearity deviations below 4.5 µm in the direction along the senor and 22 µm in the direction perpendicular to the sensor.
