【Abstract】 According to the optical wave theory about optical interference,the equal inclination interference in an isosceles triangular wedge with a big vertex angle has been concretely introduced and analyzed in detail;the interference conditions and the distribution laws of interference rings are deduced and discussed,which are in accordance with the observed phenomena in a verification experiment.On the other hand,the application possibilities of this interference principle in different fields of optical technology,especially in the field of optical micro-displacement sensor,are also discussed;and its subsidiarity to the pedagogical practices about optical interference,especially equal inclination interference,is emphasized;the teaching contents about the equal inclination interference are extended更多还原
