Assignee: KYOCERA CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An electromagnetic wave detection apparatus comprising:
a separation unit configured to separate electromagnetic waves propagating in a first direction and propagate the electromagnetic waves in a second direction and a third direction;
a first detector configured to detect the electromagnetic waves propagated in the second direction;
a propagation unit comprising a plurality of pixels arranged along a reference surface, the propagation unit being configured to switch a propagation direction of electromagnetic waves that are propagated in the third direction and are incident on the reference surface between a fourth direction and a fifth direction at each pixel;
a second detector configured to detect the electromagnetic waves propagated in the fourth direction; and
a blocker configured to block at least a portion of the electromagnetic waves propagated in the fifth direction,
wherein
the first detector is disposed in the fifth direction relative to the propagation unit;
the blocker is disposed in the fifth direction relative to the propagation unit and is disposed between the propagation unit and the first detector; and
the blocker is disposed between the first detector and the separation unit, causes the electromagnetic waves propagated in the second direction to propagate towards the first detector, and blocks propagation towards the first detector of the electromagnetic waves propagated in the fifth direction.
