Simulation of Teman green interferometer based on MATLAB
2022-07-06 07:26:00 【In the wind °】
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 = 50 c m { {Z}_{1}}=50cm Z1=50cm; Z 2 = Z 3 = 40 c m { {Z}_{2}}={ {Z}_{3}}=40cm Z2=Z3=40cm; Z 4 = 100 c m { {Z}_{4}}=100cm Z4=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 :
3、 ... and 、 The resource acquisition
The above simulation program can be obtained from the following link :
