collimated

The laser is collimated but not focused so by your logic it will be fine.

But it works better if the light is even, the light is collimated, the light is focused, the light is controllable (ie.

The eye strain and focus issues are solved by using pre-collimated laser light instead of LEDs.

You're right of course, it can't rely on collimated light like the normal Schlieren system.

It's not collimated, and it's not going to be in focus anywhere but on-target.

The events collimated in what became the launch and initial growth of Firefox.

Glass uses the same technology as the military HUD - throwing collimated light into your eye and using your retina as the screen.

Have you noticed that we haven't seen even the slightest attempt at a camera shot of the collimated display?

Would anyone one consider a collimated beam of neutrons to have a temperature?

I've tried my best at home with ghetto optics/techniques to get something near a collimated setup.

Their design flaws are many, but top among them is that their low beams are simply too collimated and too bright for safe use.

I have no idea why this might be limited by the light source being collimated?

And various existing pieces of human effort are brought into focus and collimated by nudging the lens in different directions with a "prompt".

It's like inventing a device to produce collimated beams of light, and then naming it "laser" for "laser is not an acronym" when everyone knows what it actually means.

And you get no risk reduction from supernovas / GRBs by spreading out across planets -- even collimated GRB "beams" are several degrees wide [1], a spot size light-years across (inner solar system is merely light-minutes across).
