Optics - reduce image and launch into optical fiber

[Kururunfa]

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!

Hello Filipe,

Thank you for your question. Yes, it is possible to reduce an image and launch it into the core of an optical fiber. This process is known as image fiber coupling and it is commonly used in various applications such as endoscopy, microscopy, and imaging systems.

The first step in this process is to reduce the size of the image to match the core diameter of the optical fiber. This can be done using lenses, mirrors, or other optical components. The reduced image is then directed into the core of the fiber using a coupling mechanism, such as a lens or a prism. The light from the image is then transmitted through the fiber to the other end, where it can be viewed or analyzed.

There are various factors that need to be considered in order to achieve efficient image fiber coupling. These include the numerical aperture of the fiber, the quality of the optics used, and the alignment between the image and the fiber core. Additionally, the type of fiber used also plays a role in the efficiency of coupling. For example, single-mode fibers are more suitable for coupling small images, while multimode fibers are better for larger images.

I hope this information helps. Please let me know if you have any other questions or if you need further clarification.

Best,
