Description
The simple Michelson interferometer is used as the basic method for detecting gravitational waves (GW). The arms of the ideal interferometer are hundreds of kilometers long, so it is necessary to implement a Fabry-Perot cavity (FP) to amplify the signal and detect the gravitational wave in a smaller-scale interferometer. The objective with the interferometer is to observe a phase difference in the electric field that propagates in the directions of the two arms, due to the passage of the gravitational wave. The neutrino detection method can be done using Cherenkov radiation. When the neutrino collides with an atomic nucleus in which the particle's speed is greater than the speed of light in the material medium, the product of this interaction can emit Cherenkov radiation. Then the emitted light is detected by optical sensors, allowing the trajectory and energy of the original neutrino to be reconstructed.
