Modal noise caused by the nonuniform quantum efficiency of a detector is analyzed. Laser partition noise is taken into account in the analysis. The signal-to-noise ratio degrades to about 30 dB in the presence of only a 2% nonuniform detector quantum efficiency. The signal-to-noise ratio dependence on laser-partition noise is clarified.
