Other possible techniques involve a combination of VIRGO and GOLF data to use the phase information between the ... analog signals of the SPM are measured simultaneously by three dedicated channels of the common data-acquisition system. ... The spectral bandpass is defined by a 5 nm bandwidth interference filter placed in front of the telescope with center ... the detector array by tilting the secondary mirror of the telescope using two orthogonally placed piezoelectric actuators.
