If you erase the red lines in your drawings, you'll see exactly what you'll get: a very small blue line representing a very dimm ray of light and no image at all.

Imaging yourself looking through a tube with a diameter of 1/2 inch and 20 feet long. No angle of view what so ever remains ....
Maybe a faint light at the end of the tunnel, if the light source is strong enough (and no!!! don't ever look into the sun or a laser!!)
