Thank you for quick reply. This is my attempt to represent Fb as a function of displacement a
But I am not sure is it right or not. Cause If I substitute Fb onto mass-spring equation. Due to additional mg, the result is not as I expected.
Hope to hear from you guys opinion.
Thank you.
My attempt is approaching this problem like the mass spring model. Considering the buoyancy force as spring force. By doing so, we can have the typical mass-spring equation
𝑚 (𝑑^2 𝑥)/(𝑑𝑡^2 )+Fbuoyancy = 𝐹_𝑒𝑥𝑡
Then I can assuming the displacement a will be the sinusoidal function...
Thank you all for your replies ! I am appreciate it.
1. We tried to match the imaging condition first before finding the interferogram; we used a resolution test target in the middle of 2 objective lenses and adjusted the CCD and tube lens distance. ( I did not mention tube length in the...
This is the setup diagram.
Sadly I do not have the option to use laser.
I use Thorlabs CSBLS SLS201L as light source.
But I also use a 700nm filter in front of CCD camera to make it easier to find the interferograms.
I am trying to make the white light Mach Zehnder Interferometer. After going here and there, I got this small interference pattern. Sadly.
Due to the configuration, the beam size of the two arms is not the same ( One arm is equipped with two object lenses, so this arm has a smaller beam size)...
Basically this is the Exercise In Fundamentals of Photonics book.
We also need to use these two equation (1) and (2)
As we all know, in order to make the z' as far as possible, we must place 2 lens with this distance
I already figure that thank to the initial condition of the first lens...
