Modern Fabry-Perot interferometers use image plane array detection to obtain the multiplex advantage. The imaging quality of these image plane detectors (IPD's) limits their ultimate resolution and usefulness. The influence of pulse spreading on photon-counting IPD's is investigated, first theoretically and then experimentally on real devices. The model developed in our study is in good agreement with laboratory measurements and suggests a more reliable technique to measure the blurring of the Fabry-Perot fringe caused by the IPD. Based on the model, an anticoincidence detection circuit is designed; the circuit is simple, greatly reduces the blurring, and increases the resolution of the IPD.
