deepobserver

PRINCIPLE OF deepobserver

• Based on low coherence interferometry

• Superposition of reference beam and

sample beam

• Detection of spectrum

• Transform to depth profile of sample

(surface for non transparent materials)

WELD DEPTH MEASURMENT

• Weld depth

• Weld surface

• Part surface

• Gap position

COMBINATION OF MULTIPLE SENSORS

• Combining multiple sensors for analysis of multiple types

of part errors, e.g. weld depth, pores, …

POWERTRAIN WELDINGS

deepobserver: real depth measurement and control

processobserver: find pores, instabilities; measure width

WELDING OF CYLINDRICAL PARTS

(OVERLAP SEAMS)

deepobserver: control of weld depth, avoid full penetration

processobserver: detect gap between cylinders
