Optics - reduce image and launch into optical fiber

Click For Summary

Discussion Overview

The discussion revolves around methods for reducing an image and efficiently launching light into the core of an optical fiber. Participants explore both active and passive approaches, focusing on the transmission of light rather than the spatial distribution of the image itself.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about methods to gather all light from a scene and launch it into an optical fiber without focusing on the image's spatial distribution.
  • Another participant suggests breaking the image into pixels, encoding it, and modulating the light for transmission, indicating a more active approach.
  • A different participant questions the necessity of modulation and proposes using existing optical devices that can collect and focus light for practical applications, suggesting that such devices might be a simpler solution.
  • The original poster expresses interest in a passive approach using lenses rather than an active modulation method, seeking further clarification on the proposed techniques.
  • There is a request for links to optical devices that could serve the intended purpose, indicating a search for practical examples or solutions.

Areas of Agreement / Disagreement

Participants have differing views on the best approach to achieve the goal, with some advocating for active modulation techniques and others preferring passive methods. The discussion remains unresolved regarding the most effective strategy.

Contextual Notes

Participants have not fully explored the technical limitations or assumptions underlying their proposed methods, and there is no consensus on the feasibility of the suggested approaches.

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:
