Simulation of Teman green interferometer based on MATLAB

One 、 principle

The principle of Teman green interferometer is shown in the figure below ：mirror 1 It is a plane reflector ;mirror 2 Yes, the amplitude is 1μm Wisdom difference of .

Two 、 Simulation results

Set the simulation parameters to ：

$Z_1=50cm$;$Z_2=Z_3=40cm$;$Z_4=100cm$;

At this time, the beam splitting ratio of the beam splitter is 3:7

simulation process ：

1)  Define the initial light wave , And define the aperture size of light wave .
2)  The simulated light propagates to the beam splitter 
3)  Beam splitter 3:7 Simulation of light intensity attenuation 
4)  The light beam propagates to mirror1; ( Reference light )
5)  The light beam propagates to mirror2     ( Object light )
6) mirror2 Aberration simulation on ( Simulation of the measured object ) At this time, it can be replaced by any measured object !
7)  Simulate the reflection of object light 
8)  The reference beam returns to the beam splitter 
9)  The object light beam returns to the beam splitter 
10)  Beam superposition ( Reference light + Object light )
11)  The light beam propagates to CCD The screen 
12)  Calculated light intensity 

The simulation results are as follows ：
