Abstract :
A new, very well balanced heterodyne interferometer scheme which suffers very low common mode drift is described. Potential use of this novel interferometer for readout sensor of a biochemical reaction is discussed. Our preliminary measurement results show that an 8.7×10-7 refractive index unit can be measured.
