Experimental observations of a study conducted to investigate spectral shifting and spectral switching that take place in Young's double-slit experiment with partially coherent light are reported. It is shown that for certain critical distances in the near zone of the double slit, the phenomenon of spectral switching is observed, while for other situations a spectral shift is observed. These results are consistent with a theoretical study by Pan and Lu.

Adopting the technique of different position probes into the spectrum of partially coherent light,study the spectral shift and spectral switch of partially coherent polychromatic light in Young′s double-slit experiment.The experimental results show that,in the interference field,the normalized spectrum is redshifted at some observation points,is blueshifed at others,and the spectral shift changes rapidly from red shift to blueshifted at the critical points,i.e.,the spectral switch occurs.Furthermore,it is shown that the slit parameter and observation distance effect on the spectral shift and the spectral switch in Young's double-slit interference experiment.
