Multisensor 3-D Inspection

June 27, 2011

Nikon Metrology’s HN-6060, a noncontact inspection system, uses laser scanning, five-axis synchronized hardware control, and powerful processing software for the inspection of complex shapes, including gear teeth, turbine blades, and appliance housings.

The laser scanning sensor extracts the surface form and waviness data in one scan. This reveals all shape and waviness information in one measurement. The metrology system’s laser scanner and shape from focus (SFF) sensor use active texture projection to perform high-precision measurement of shapes even if they have glossy surfaces or no surface texture. Touch probes and optical heads with built-in TTL laser AF complete the multisensor system. This allows it to perform shape measurements on parts such as complex automotive and machined components, molded parts, and medical devices.

Another core element of the device is its five-axis synchronized hardware control. This allows optimum part orientation to the sensor, allowing measurement from different angles.

The system’s software features macrobased teach in, simulation for collision avoidance, easy acquisition of point clouds from 2-D and 3-D shapes, and part-to-CAD comparison.
