Abstract:

Looking into a cylindrical metal tube with smooth inner walls，bands with discontinuous

distribution of brightness can be found. The basic principle of this phenomenon is preliminarily

verified by mirrors. In this pa- per，the basic principle of the phenomenon is explained by

establishing the model and using MATLAB to simulate. Finally，the combination of experiment and

simulation is used to explore the series of factors which affect the phe- nomenon.

Key words: metal tube, bands, reflection of light, MATLAB simulation
