1. An electromagnetic wave detection apparatus comprising:
a switch comprising an action surface with a plurality of pixels disposed thereon, the switch being configured to switch each pixel between a first state of causing electromagnetic waves incident on the action surface to travel in a first direction and a second state of causing the electromagnetic waves incident on the action surface to travel in a second direction;
a first detector configured to detect the electromagnetic waves that travel in the first direction;
a second detector configured to detect the electromagnetic waves that travel in the second direction; and
a controller configured to select a smaller number of pixels than Timg/Tdis as targets of switching from among all of the pixels in the switch in a configuration in which a value of Timg/Tdis is less than a number of pixels in the switch, Timg is a time for generating one frame of image information and Tdis is a time required to switch an arbitrary pixel in order from the first state to the second state and back to the first state, and
wherein the switch is configured to switch each of the plurality of pixels between the first state and the second state according to an irradiation region of the electromagnetic waves emitted from an irradiator.
