Electromagnetic wave detection apparatus, program, and information acquisition system

An electromagnetic wave detection apparatus comprising:

• an irradiator configured to emit electromagnetic waves:
• 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, including reflected waves, from an object, of electromagnetic waves irradiated from the irradiator, 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, which is a passive detector, configured to detect the electromagnetic waves that travel in the first direction;
• a second detector, which is an active detector, configured to detect the electromagnetic waves that travel in the second direction;
• and
• a controller configured to compensate for a signal strength, corresponding to electromagnetic waves travelling to the second detector, in the first detector, such that the controller is configured to compensate for a reduced signal strength by the electromagnetic waves travelling to the second detector, in the first detector, 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 the irradiator.
