We report one-dimensional small displacement measurement of TEM00 mode with balanced homodyne detection. The smallest measurable displacement in our experimental setup is 0.3 nm. The conjugate properties of displacement and tilt are tested. Finally we analyze the effect of the deviation of local oscillator beam from TEM10 mode on the displacement measurement result. Experimental results are consistent well with the theoretical analyses.
