Anomalous Behaviour of the Spectra in Young＇s Double-Slit Interference Experiments

PUJi-Xiong, CAIChao

It is shown that an anomaly of the spectrum takes place in the interference field when Young's double-slit interference experiment is illuminated by spatially coherent polychromatic light. Specifically, drastic spectral changes (i.e. the spectral shifts exhibit a rapid transition) occur in the vicinity of the dark fringes. The potential applications of this spectral anomaly are also considered.

Spectral anomalies in Young's double-slit interference experiment

Jixiong Pu, Chao Chi, Shojiro Nemoto

We report a phenomenon of spectral anomalies in the interference field of Young's double-slit interference experiment. The potential applications of the spectral anomalies in the information encoding and information transmission in free space are also considered.

The Spectral Shift and Spectral Switch in Young′s Double-Slit Experiment

QU Biao

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.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.

Experimental observation of spectral changes of partially coherent light in Young’s experiment

Bharat Kumar Yadav, Syed A. Rizvi, Hem Chandra Kandpal

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.

Strange patterns of light

Tao Tang

In a modern version of Young's double slit experiment, a laser beam passes through two narrow slits and creates an interference pattern of bright and dark fringes on a distant screen. We place magnifying glasses between the double-slit and the screen, and when a laser beam passes through the double-slit and magnifying glasses, strange patterns will appear on the screen.
