We calculate the initial phase difference of the homodyne fiber interferometer by measuring the interference photocurrent and the photocurrents from the two fiber arms on a temperature control plat. The fiber is very sensitive to the variation of temperature, so it is necessary to study the temperature characteristics in the phase measurement of homodyne fiber interferometer. By the experimental study of this paper, we can know that the variation of the phase difference of the two fiber arms is proportional to the variation of the temperature. This conclusion agrees well with the theory analysis. To my knowledge, the quantitative research on this aspect is seldom mentioned before.
