    Refraction and fiber optic cable diameter

    I'm not trying to image, just pass light from a flashlight into one end and out the other to be used for light to see. Rigid works, flexible is better. Light guides are the closest I've seen so far. I can adapt from the light guide concept and go from there. Thanks for pointing me in the right...

    Refraction and fiber optic cable diameter

    That could possibly work. A light pipe (Thank you Andy Resnick) is what I believe the term is what I am looking for.

    Refraction and fiber optic cable diameter

    Thanks for answering and good points berkeman, I am not particularly concerned with transmitting data or signals, and so I believe that dispersion wouldn't play a bad role as long as the light was a guided ray the whole time. You could say that I want to be able to use the fiber optic cable like...

    Refraction and fiber optic cable diameter

    Hello there, I'm wondering if there is any restricting reason why fiber optic cables are not made thicker. Regardless of the practical applications, is there any reason you can't make a fiber optic cable that is only 2m long but 2cm thick (compared to the normal 0.0125 cm thick)? Does width of...

    Judging distance of a light source

    I'm interested in short distances, from about 1-1000 meters. Thank you for your guidance so far, I'm looking into the way cameras tell distances when focusing like Dave pointed out.

    Judging distance of a light source

    Is there a way to judge the distance of a light source, or from where it was last reflected, by analyzing the characteristics of the light? Are there any properties of light that change, or better yet, consistently change over distance? I'm trying to figure out if somehow there would be a way to...
