Death ray new approach

  1. Dec 28, 2014 #1
    When people attempt to build one, they usually put objects near its focal point in front of the mirror but i wonder, has anybody tried "collecting" the light and aligning the beams in some way to be used as one? I know that the light is coming under different angles but is it possible to align at least a portion of the light reflected from the mirror via a system of smaller mirrors? Do you know about a blog or someone who has tried something similar or is it practically impossible?

    Sorry for my childish idea, i already forgot high school optics, here is the doodle:

    I'm sorry, but there's no such thing as a death ray so we can't give you any answer based om the laws of physics.

    If you want to start a thread about a specific question in optics, or a discussion of the physics of beams of radiation of various types, that's OK in the appropriate subforum, but this thread is closed.
