| 11. | Light from a laser is expanded by a diverging lens ( not shown ), then is collimated into a parallel beam.
|
| 12. | "It's not likely that all the parallel beams will hit the same turbulence, " which is usually quite local, Willebrand said.
|
| 13. | The radio waves are emitted back toward the dish by the feed antenna and reflect off the dish into a parallel beam.
|
| 14. | A parallel beam, with wave vector \ mathbf { k } _ i is incident on a square lattice of parameter a.
|
| 15. | In other words, parallel beams of light travel in straight lines and never meet, just like parallel lines in high school geometry class.
|
| 16. | A point source of monochromatic light is expanded by a diverging lens ( not shown ), then is collimated into a parallel beam.
|
| 17. | It consists of a two-track composite construction with two parallel beams connected by diagonal steel girders and a deck made of a concrete slab.
|
| 18. | "' Fig . 3 "': Considering a parallel beam irradiation optical system where the angle between the object and all transmission lights equals ?.
|
| 19. | I want to convert the light from a single LED to a parallel beam so that it can travel further at a given intensity.
|
| 20. | Hence, object ( 1 ) will not be moved while the parallel beam irradiation optical system are rotated around the object ( 1 ).
