Control device, irradiation system, control method, and program

An irradiation system comprising:

• a plurality of irradiation devices arranged adjacent to one another in a first direction;
• and
• a control device that controls the plurality of irradiation devices,
• wherein each of the plurality of irradiation devices comprises a reflector which is able to move an irradiation position of an electromagnetic wave in a second direction different from the first direction while moving the irradiation position of the electromagnetic wave in the first direction, and
• wherein the control device controls such that the irradiation position of the electromagnetic wave of each of the plurality of irradiation devices is separated from the electromagnetic wave of another of the plurality of irradiation devices by a predetermined distance or more in the second direction at a predetermined timing.

A program that causes a computer to function as a control device for controlling an irradiation device,

• the irradiation device comprising a reflector which is able to move an irradiation position of an electromagnetic wave in a second direction different from a first direction while moving the irradiation position of the electromagnetic wave in the first direction,
• the program providing the computer with:
• a function of storing information indicating how much the irradiation position of the electromagnetic wave is shifted from a reference in the second direction;
• and
• a function of receiving the reference in the second direction and controlling an irradiation direction of the electromagnetic wave using the received reference and the stored information.
