In this study, the pretilt angles in the surface stabilized ferroelectric liquid crystals(SSFLC) were evaluated by optical experiment. We measured the temperature dependence of the pretilt angles from nematic phase through smectic C^* phase by the optical measurements such as the crystal rotation method. Especialy for the SmC^* phase (SSFLC mode), the pretilt angle was calculated on a basis of the molecular orientation model of SSFLC by using the measured values of the layer tilt angle, the swiching state angles and the memory state angles. In consequence, it was found that the temperature dependence of the pretilt angle exhibited an discontinuity near the N-SmA transition temperture, and the pretilt angles in smectic A phase were smaller than that in nematic phase. Furthermore, it was suggested that the pretilt angles in the SSFLC cells depend on the alignment films in the same manner as nematic cells.
