ABSTRACT:
Light emitted from a taking lens20enters a first birefringent plate1ato be spatially divided along a first direction extending perpendicular to the direction in which the light advances to achieve two separate rays L10and L20. The vibrational planes of the two light fluxes L10and L20emitted from the first birefringent plate1aare converted to a circularly polarized light by a phase plate1c. The two light fluxes L10′ and L20′ emitted from the phase plate1care each spatially divided into two by a second birefringent plate1dalong a second direction extending perpendicular to the first direction to achieve four separate rays L11, L12, L21and L22, to be guided to an imaging plane15aof an imaging device15. At least either the first birefringent plate or the second birefringent plate is constituted of lithium niobate, rutile, Chilean nitrate, or the like.
