Study On The Application Of Sencond Order Coherence Of Light

The study and application of the nature of light,whether in the past or in the present,is a hot topic of concern,and the coherent nature of light occupies an important position in optical studies.From the time that Young's Double slit experiment,which proving the the wave aspect of light,the research and application of the first order correlation of light has been ongoing for hundreds of years.In the recent decades,the discovery of the second order correlation of light results in many applications,including correlation imaging.When studying the second order correlation of light,we find that it can be used to measure the speed of liquid containing scattering media,and this is also an important application.
