OLPF
As solid-state imaging sensors （CCD,CMOS,etc.）such as vidicosn load spirits read out images by uncontinuous shooting ,so there will be some unnecessary optical interference noise(Moire effect) when shooting striola,also periodic spectral overlap aliasing and color striola signal interference,which affects the picture definition.
OLPF consists of single OLPF and multiple OLPF and makes use of the birefringence effect of quartz crystal.When the light of target image information passes through OLPF,there will be the phenominon of birefrication.The night will be divided into two parts:usual light and unusual light.Then take advantage of different angles of optical axis to make their images apart.,and the distance just meets that of eleminating an one-dimensional interference stripe.And this phenominon can weaken and eliminate LF color interference stripe, especially for false color and interference stripe in color CCD.
