Current profile 

The names "John Doe" or "John Roe" for men, "Jane Doe" or "Jane Roe" for women, or "Johnnie Doe" and "Janie Doe" for children, or just "Doe" non-gender-specifically are used as placeholder names for a party whose true identity is unknown or must be withheld in a legal action, case, or discussion. The names are also used to refer to a corpse or hospital patient whose identity is unknown. This practice is widely used in the United States and Canada, but is rarely used in other English-speaking countries including the United Kingdom, whence the use of "John Doe" in a legal context originates. The names "Joe Bloggs" or "John Smith" are used in the UK as placeholder names, (mainly to mean 'any old person', the classic 'Everyman') as well as in Australia and New Zealand.

Absolute distance measurement

Focus: 
Precision Experiments

Most of the length measuring interferometers are working incrementally. Thus beam interruptions are causing errors in distance measurement. This interruptions might happen accidentally by parts moving through the beam or on purpose when the distance to different mirrors shall be measured. To afford distance measurements with possible beam interruptions an absolute length measurement is needed.

Micro Coordinate Measuring Machine for Parallel Measurement of Microstructures

Focus: 
Metrological Instrumentation

This project deals with the development of a coordinate measuring machine for parallel tactile probing of microstructures. The particular challenges due to the parallel probing will be discussed and the concluding results regarding the construction, the control and the simulation environment will be outlined.
