Description
このような光源部100は第1光源120及び第2光源140の二つからなることができ、第1光源120と第2光源140は固有の偏光を持つことができる。すなわち、第1光源120と第2光源140は同一仕様に構成されるが装着角度を異にして偏光ビームの方向が互いに異なるように構成することができる。
また、第1光源120と第2光源140は相異なる方向の偏光ビームを照射するように構成されることで、第1光源120は縦方向の偏光ビームを照射し、第2光源140は横方向の偏光ビームを照射するようにすることができる。このように、第1光源120と第2光源140は相異なる方向の偏光ビームを照射するように構成することにより、同一位置に取り付けられても偏光ビームの方向を異にすることができる。
