Diffraction effects in slit experiments

AI Thread Summary
In the double slit experiment, diffraction effects cause traces from one slit to appear even when the other is open. This modulation in the diffraction pattern results in a decrease in overall intensity as one moves away from the center. It is an inherent characteristic of diffraction patterns that cannot be completely eliminated but can be suppressed. To reduce the visibility of this modulation, one can approach the experiment from the perspective of single slit diffraction. Understanding these principles is crucial for effectively managing the observed effects in slit experiments.

In double slit experiment with a single source,I am finding the traces of one slit when I have the other one open. I think this is due to diffraction effects.May I know how to tackle this?

Do you mean the diffraction pattern of the double slit exhibits some kind of modulation where the overall diffracted intensity become less and less as you go further from the center? If that's what you mean, you are right that's an effect inherent in a diffraction pattern. Which means you can't completely remove this effect from your experiment, you can only suppress it. As you have said such modulation is reminiscent of the single slit diffraction pattern. So you can think of something of how to make this modulation less apparent by thinking the experiment in term of single slit.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
