例句與造句

1. The detector alternates between measuring the sample beam and the reference beam in synchronism with the chopper.
2. A double path interferometer is one in which the reference beam and sample beam travel along divergent paths.
3. The sampled beam has much lower intensity and can be measured by a scanning-slit or knife-edge profiler.
4. A common path interferometer is a class of interferometer in which the reference beam and sample beam travel along the same path.
5. The difference between the reference beam and the sampling beam thus reveal the properties of the sample in the way it scatters light.
6. It's difficult to find sample beam in a sentence. 用sample beam造句挺難的
7. After being perturbed by interaction with the sample under test, the sample beam is recombined with the reference beam to create an interference pattern which can then be interpreted.
8. At detector 2, in the absence of a sample, the sample beam and reference beam will arrive with a phase difference of half a wavelength, yielding complete destructive interference.
9. If a sample is placed in the path of the sample beam, the intensities of the beams entering the two detectors will change, allowing the calculation of the phase shift caused by the sample.
