Abstract:In response to the problem of students needing to visually count a large number of fringes when measuring laser wavelength withthe current Michelson interferometer,based onthe existing Michelson interferometer,the fringes are recorded using the Phyphox software on a smartphone,and the number of fringes is read out using Excel software to achieve fully automatic counting.The results indicate that compared to traditional experiments,using Excel software and smartphone autonomous counting experiments can avoid eye fatigue and improve measurement accuracy.
