| Abstract: | Two mechanisms for realizing tunable centre wavelength of F-P cavity interference fllter are presented.A typical filter structure which denter wavelenth is changed by changing cavity length is shown and its corresponding voltage-driving circuit is given.It is indicated experimentally that a proper pre filter of light amplifier can be used to increased the sensitivity of a system. |
