A simple method for characterizing effective intensity of Franz Keldysh effect of (HgCd)Te detectors was presented.It is using the output ratio of different bias voltage instead of wavelength shift to characterize effective intensity of Franz Keldysh effect. The experimental result shows this method is effective and practical.
