Optics - reduce image and launch into optical fiber

AI Thread Summary
To reduce an image and launch it into an optical fiber, one approach involves breaking the image into pixels, encoding it, and modulating the light for transmission. However, there is interest in a passive method using lenses to gather and focus light without the need for active modulation. Participants discuss the feasibility of using existing optical devices that collect and distribute light effectively in residential settings. Suggestions include exploring these devices for practical applications. The conversation emphasizes the need for both active and passive strategies in optical fiber light transmission.

Dear all,

I'd like to know if there is a way of reducing an image and launching it into the core of an optical fiber.

By other words, I'm not interested in the spatial distribution of the light (the image itself) but I'm interested in gathering all the light coming from the scene and launching all this light into the core of an optical fiber.

Any help/suggestion on this?

Thank you very much in advance.

Break the image into pixels, encode it, and modulate the light being launched down the fiber.

Reverse the process on the other end of the fiber.
 
That's very interesting and I'd love to hear more about how this is done but , Why can't you just use a lens? There are optical devices available for use in homes that collect a lot of light, focus it, move it into the house and spread it back out again to provide indoor lighting without putting a big hole in your roof. You might try to find one of those and see just how it works?
 
Antiphon,

how would you suggest to do that? It seems your approach is an active one, i.e., I would need to modulate the encoded light with some sort of light source and encoded after detecting it with a detector, such as a camera, for instance, right?
I would be more interested in a passive approach, built with lenses, for instance...

netgypsy,

can you give me a link or two for those devices that you spoke about? It seems a good possibility.

Any other ideas?

Thank you all! :smile:
 
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...
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...
