This paper presents a theory of a highly sensitive total internal reflection (TIR) sensor for measuring wavelength shifts. The system consists of a diffraction grating, and a high-sensitivity TIR heterodyne interferometer. As a heterodyne light beam strikes a grating, the +1st order diffraction beam is generated. The light then penetrates into a high-sensitivity TIR apparatus at an angle larger than a critical angle. A wavelength variation will change the diffractive angle of the +1st order beam, thus inducing a phase difference variation of the light beam emerging from the TIR apparatus. The numerical simulation demonstrated that the sensitivity and the resolution of 3.6/nm and 0.01nm can be achieved.
