Summaries

23. Summaries
• Simulation of system of detecting 1-d motion
of cylindrical transparent grains using narrow
laser beam has been built
• Sensor reading is still hard to be formulated
for representing the physical result if it is so
constructed in hardware as assumed
• Object position will influence the results
