Embodiment Construction
[0014] The patent of the present invention discloses the technical evolution route of researching optical interferometer by using TRIZ and optical interference principle. According to the high frequency band (10Hz-10kHz) is the most sensitive frequency band of the laser interferometer for detecting gravitational waves on the ground; the middle frequency band (0.1Hz-10Hz) is the short arm length (10 3 -10 5 km) the most sensitive frequency band of the space gravitational wave detection laser interferometer; the low frequency band (10 -4 Hz-10 -1 Hz) is the arm length of the laser interferometer for detecting gravitational waves in deep space (10 6 -10 9 km) the most sensitive frequency band. We analyze ground-based laser interferometer gravitational wave detectors, such as figure 1 As shown, it is found that the adaptability of the instrument system to detect low- and medium-frequency gravitational waves is poor. According to the 2008 TRIZ contradiction matrix table, the "...
