- Abstract:
- This paper describes the use of a CD pickup head as a displacement measurement system. First, the components contained in a pickup head are explained and how they are combined to obtain the functionality of a pickup head. Afterwards, the application of measuring a knife edge profile is introduced.The results revealed some insuffiencies with the current system. Nevertheless, the cutting edge’s radius of curvature can be estimated.
