研究目的
Investigating the generation of N00N-like interferences with two thermal light sources for imaging applications with increased resolution.
研究成果
The study demonstrates that N00N-like interferences of arbitrary order can be produced with two thermal light sources, offering potential applications in astronomy for imaging with increased resolution. The experimental results align well with theoretical predictions.
研究不足
The visibility of the N00N-like interference pattern is reduced compared to quantum mechanical N00N-states. The approach is limited by the finite extent of the slits and the discrete pixel size of the digital camera.
1：Experimental Design and Method Selection:
The study involves measuring the M th-order intensity correlation function of light from two thermal sources to observe N00N-like interferences.
2：Sample Selection and Data Sources:
Two statistically independent thermal light sources are used.
3：List of Experimental Equipment and Materials:
A frequency-doubled Nd:YAG laser at λ = 532 nm, rotating ground glass disc, double slit mask, and a digital camera.
4：Experimental Procedures and Operational Workflow:
Light is scattered from a rotating ground glass disc to create a speckle field, which illuminates a double slit mask. The far-field intensity correlation functions are measured using a digital camera.
5：Data Analysis Methods:
The normalized M th-order correlation functions are evaluated by cross-correlating intensity grey values from fixed and moving pixels.
