		Leica T-Scan is a non-contact 3D geometry measuring system of hand-held type. You hold with one hand the laser sensor T-Scan that is not mechanically restrained, to project 90 mm wide laser light over the measuring subject, and move the sensor unit along the geometry of the subject. By so doing, this novel system rapidly measures complicated geometries. The tracker calculates in real time the position and tilt of the hand-held sensor. The measuring range is 30m at maximum in diameter from the tracker, enabling accurate measurement of large workpieces. The laser sensor is hardly affected by the color or gloss of the surface to be measured. So powdering before measurement is not necessary. Since the system can be freely moved, measurements can be made in the manufacturing site. Tracker This unit with a laser interferometer and a CCD camera calculates accurately the spatial position and angle of the laser senor T-Scan and contract T-Probe. This innovative unit provides large measuring range and high precision measurement, the features conventionally incompatible with each other. Even with a single tracker unit, it is possible to perform 3D measurement in a range up to 4160 m in diameter and calculation of the trajectory of measurement subjects, if a reflector is used. Specification of the laser tracker   AT 901-B AT 901-MR AT 901-LR Measurement method Laser interferometer and absolute distance meter Measurement range (reflector) 160m diameter 50m diameter 160m diameter Measurement rangee (T-Probe/T-Scan) ------- 18m diameter 30m diameter Measurement range: angle Horizontal/vertical 360°/±45° T-Scan You hold with one hand the laser sensor T-Scan that is not mechanically restrained, to project 90 mm wide laser light over the measuring subject, and move the sensor unit along the geometry of the subject. By so doing, this novel system rapidly measures complicated geometries. The measuring range is 30m at maximum in diameter from the tracker. The laser sensor is hardly affected by the color or gloss of the surface to be measured. So powdering before measurement is not necessary. Specification of the T-Scan Measuring depth 78mm Scanning width 90mm Focal distance (average) 86mm Sampling rate 20,000 points/second Line frequency up to 140 lines/second Point spacing on the scanning line 0.07mm - 0.98mm Outer dimensions of the sensor 185×100×145 mm Weight of the sensor 1200g Laser class Class 2 Laser type Diode Wavelength 670 nm T-Probe This is a wireless touch probe that can be held with one hand, compact in size, light in weight and excellent in accuracy. You can change the stylus length at the end of probe, during measurement. This probe is capable of easily measuring depths of complicated geometries, difficult with a conventional probe. Specification of the T-Probe Maximum measurement range 30m diameter Angular admissible range Roll 360 Pitch ± 45 Yaw ± 45 Data output rate 1,000 points/second Tracking rate >1m/s Weight 670g Jig measurement Robot calibration Reflector Point measurement with the laser tracker and reflector achieves high accuracy in a wide range. Suitable for point measurement and repetitive checks on jigs, point measurement and assembly inspection of automobiles and aircraft, and robot calibration. Developed by Leica Geosystems, Switzerland
