The invention discloses a transient
ultraviolet multispectral
radiometer, comprising a plug-pull type aiming lens, a guide rail component, a cassegrain imaging
system, an
ultraviolet spectrograph, a CCD
driving circuit, a high-speed collection storage
system and a computer which is provided with a spectrum measure
data processing soft
package. The cassegrain imaging
system aims at a
light source to be detected with the help of the aiming lens, adjusts self-focal distance and makes the
light source to be detected for imaging clearly on the incidence slit of the
ultraviolet spectrograph; the output optical
signal of the ultraviolet
spectrograph is converted to an electrical
signal through the CCD
driving circuit and is collected and stored by the high-speed system, and then is transmitted to the computer by a
USB line. The spectrum measure
data processing soft
package calculates the spectrum power curve, the
peak value wavelength, the corresponding power value of the
light source to be detected according to relevant calculation means. The invention not only can detect the ultraviolet spectrum of the
microsecond transient line light source and the transient side light source during single flashing time, but also can detect the ultraviolet spectrum of the
steady state radiation light source including weak energy or the far
radiation light source, and has good application prospect.
