查询词典 slit

The optical element comprises: a plurality of rectangular prisms for dividing linear visual field, and is characterized in that the effective work area of each rectangular prism is a linear narrow slit, which can perform visual field division of the light beam from a long linear geographical object and turn the divided visual field into separate light beams for the rational space arrangement of the subsequent optical elements.
