Abstract
Conditions at which phase of light demonstrates a markedly different behavi or for close values of system parameters as well as the Heaviside jump are discussed and explained in terms of phase topology. On this basis, a method of interferometric surface plasmon resonance imaging is proposed and appli ed to develop ultrasensitive affinity array sensors with a monoatomic thick ness resolution.
