AbstractAt present, the mutual restriction between the spectral resolution and the dynamic range limits the further improvement of the spectral property of Talbot spectrometer. This mutual restriction is caused by the matching problem of grating and detector. Here, a method, which focuses on eliminating the relationship between grating and detector in the design of Talbot spectrometer, for masking detector to cover the (phase-inverted) self-imaging is introduced. Both theoretical simulation and experimental analysis validate the method, which maintains the contrast of pattern while changing the size of pixels and thus the matching problem no longer exists. Overall, this method breaking the bottleneck of spectral property for current talbot spectrometers, which makes the system design more flexible and enhances the universality of Talbot spectrometer, and the spectral resolution of the spectrometer under this method can be superior to 0.3nm while keeping the contrast of pattern, better than the previously reported best spectral resolution 1nm of current talbot spectrometer.
