Laser Debris Inspection System

The system is intended for non-contact detection of the debris inside the circular grooves of different technological items, for example brake calipers and so on. The system can be used also for groove seal profiling (seal deformation inspection).

Operation of the system is based on the scanning of the item surface by binocular triangulation laser sensor.

The system contains laser sensor mounted on rotating module (Figure 1.).

Radiation of a semiconductor laser from the sensor is focused onto an item surface.

Radiation reflected by the surface is collected by two input lens of the sensor. The sensor is rotated and scans the surface. Distance to the surface, measured by laser sensor and corresponding angle of rotation form polar coordinates of the surface. In-built signal processor analyzes the surface profile and detects the presence of debris on the surface.
