Hello everyone, I have difficulty doing Speckle Image simulation of Laser Source.
The laser I use is 266nm DPSS Laser, and the C.L. is about 8mm.
My purpose is to remove Speckle by making each core length of Multi-mode fiber bundle longer than Coherence length, and to know the minimum core length, I would like to perform Speckle Image simulation at Illumination STOP according to the each core length. (Specle image simulation when sampling at least two cores)
The fiber I use is 200um core size, and the total core size of the bundle is about 6mm. How can I simulate the speckle image in this situation?
So far, I've tried...
I change this design to non-sequential, set the coherence length of the source to 8mm, and change the z-position of each source (for example, -10mm..). Next, I checked 'coherent iradiance' by placing the detector in Illumination stop position, but there was no difference.
If you have any ideas, please let me know.
