A real-time subdivision uniformity judging indexγis put forward,which objectively evaluates the quality of grating signals and the error of subdivision *** to the estimation of subdivision uniformity error |Δφ| is expressed as the equation |Δφ|≤141×γand theγis only defined by the amplitudes of subdivision signals,therefore the subdivision uniformity error |Δφ| can be obtained directly through the measurement of the amplitudes of subdivision *** experimental results show that such judging method evaluated by indexγis effective.
