1. In the research, it is found that etalon effect is also a reason for experiment error.

2. The measured parameters of the transmittance of etalon agree with the designed parameters approximately. The velocity sensitivity descended compare with the designed sensitivity.

3. Sensor element, which consists of a Fabry-Perot etalon fabricated from single-crystal silicon, connects with the LED and detector by fibers.

4. So, in effect, the etalon as a whole functions as a mirror that reflects only one specific color,[sentencedict.com] which you can choose simply by changing the spacing between the surfaces.

5. The conclusion is that F P etalon is the most effective method to realize the single longitudinal mode and others will be validated in the experiments.

6. The parameters of triple Fabry-Perot etalon, namely, free spectral range, spectral width, peak offsets between each etalon, effective aperture and so on are optimized.

7. The temporal response of a Fabry - Perot etalon filter to the short optical pulses has been studied.

8. A high precision measure method of F-P etalon spacing is proposed by measuring the moving number of transmission resonant peak with the incident angle of F-P etalon.

9. A novel method of F-P etalon perpendicularity adjusting was introduced as well.

10. In essence, it was a microscopic etalon in which the parallel reflecting surfaces were thin-film layers created using MEMS techniques.

11. Adjusting the experiment instrument needs mastering the key procedure, thereby the experiment phenomena can be got; here the most important adjustment is the F-P etalon 's.

12. Colorless operation can still be obtained since the same etalon can be used to enhance multiple wavelength channels.

13. On measuring the spectral linewidth by means of photographing the fringes of the F-P etalon, the influence of the instrument width on the measured results has been discussed.

14. Theoretical analysis and experimental research in the dispersion compensator based on F-P etalon are presented.

15. Using dye for Q-switching, a ruby laser pumped with double puke discharge was used as the light source and an etalon as the spectral analyzer.

16. Two problems has been solved of inserting the intracavity etalon and of selecting the optimal blazed grating and its orders at grazing incidence.

17. It is discussed that the shortcoming on the traditional dispersion formula of F P etalon when it is used for light spectrum measurement. A formula which can give precise result is introduced.

18. Being different from the classical physical model with Bragg′s law, the new model is based on Fabry Perot etalon, i. e. a volume hologram is consisted of a series of coupled Fabry Perot.

19. The relation between the air gap thickness and the peak wavelength in micro-optical electromechanical system (MOEMS) optical tunable filter based on Fabry-Perot etalon is discussed.

20. The principle and methods of selecting mode by resonant reflector cooperated with F P etalon are discussed and presented.

21. Emphasis is put on the experimental research on its tunable range and the bandwidth narrowing with a diffraction grating and a Fabry-Perot etalon.

22. In case the spectrum of incident beam is a function of triangular form, we calculated the spectral distribution of transmission through the F-P etalon with a computer.
