Technical details: 
• Laser head for technical using (security, working process 
control...) 
• relatively inexpensive (5000Euro) 
• accuracy cca 8mm (0.1 -10m) 
• accuracy cca 8cm (10-80m) 
Disadvantage: 
• wide laser beam = big laser trace (low detail resolution) 
• without rotating or motion device for practical using (all 
5. CONCLUSION 
Examples of inexpensive systems based on simple digital 
camera and laser are discussed in the paper. All systems are 
under construction at the Czech Technical University in Prague 
and they are used for technology testing and for teaching.
