[Problem] To provide a practical configuration for a pulse spectroscopy device that performs pulse extension by dividing and transmitting pulsed light between a plurality of fibers, wherein light is overlapped and radiated into the same region in an irradiation plane. [Solution] After broadband pulsed light from a pulsed light source 1 is divided in accordance with the wavelength thereof by an arrayed waveguide grating 3 serving as a division element, the wavelength of the light is configured to have a one-to-one correspondence with time in the pulse when the light is transmitted by a fiber bundle 21, and the light is radiated onto a subject S via a radiation unit 4. Light emitted from cores in the fiber bundle 21 is overlapped in substantially the same region R1 by a first lens 41, the region R1 being in a first plane P1 perpendicular to an optical axis A, and radiated onto the subject S by means of the image at the first region R1 being projected by a second lens 421, 422.
