INFRARED LIGHT RADIATION DEVICE, INFRARED LIGHT DETECTION DEVICE, TIME-SERIES CONVERSION PULSE SPECTROMETER, AND INFRARED LIGHT RADIATION METHOD

摘要

There is provided an infrared light radiation device capable of polarizing radiation light with a simple structure without causing loss of radiation light. The device includes: a light transmission film (22) to which pulse excitation light is applied to generate an optical carrier; a pair of first antenna electrode films (21a) formed on the light transmission film (22) via a gap (32) and radiating infrared light; a pair of second antenna electrode films (21b) formed on the light transmission film (22) via the gap (32) with an angle against the first antenna electrode films (21a) and radiating infrared light; and a control unit for applying voltage to each of the first antenna electrode films (21a) and the second antenna electrode films (21b) independently from each other. The voltage applied tot he first antenna electrode films (21a) and the voltage applied to the second antenna electrode films (21b) may be applied selectively at different times or simultaneously with different phases.
