optical path in a sentence

Examples

1. With multi wave interference ( by inserting a diffuser into the optical path ) aperiodic patterns with defined spatial frequency spectrum can be originated.
2. Thus the optical path difference between the two beams is 5 mm or 7.5 mm depending on the type of interferometer used.
3. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly different viewing angles to the left and right eyes.
4. It is inserted into a lens optical path at the plane or near the plane of the iris allowing the capture of parallax views.
5. This avoids the blooming problem because the waves from the target passed through the blooming, and therefore show the most conductive optical path.
6. Only the frequencies corresponding to the zero Optical Path Difference ( OPD ) at the mirror, up to the farthest dots are sampled.
7. The result is that light traveling an equal optical path length in the test and reference beams produces a white light fringe of constructive interference.
8. For the DVD-5 discs, where there is no layer of bonding resin in the optical path, surface coating can be used.
9. For certain wavelengths, however, the optical path length difference is an integer multiple of the wavelength, so that the losses are very small.
10. An incoming gravitational wave changes the optical path of the laser beams in the arms, which then changes the interference pattern recorded by the photodiode.
