An ultra wide band spectrogram correlation detection device comprises a scanning rotating mirror, a Cassegrain reflector set, a spectroscope, a reflector, a broadband spectrum lens set, a visible and near-infrared lens set, a long-wave imaging lens set, a charge coupled device imaging unit, a focal plane array imaging unit, a Fourier spectrum measurement unit, and a grating spectrum measurement unit. A target is preliminarily recognized and spectrum measurement is guided by means of long-wave infrared imaging and visible near-infrared imaging, a target is precisely recognized by means of the spectrum measurement, and the problem is solved that an existing detection device is incomplete in detection band, restricted in light path layout, large in device size and poor in capability of detecting moving targets and dynamically changing objects. The device is small in size, high in integration level and convenient and flexible to use and can implement ultra wide band spectrogram observation on the moving targets and dynamic changes of external sceneries as well as automatically-switched tracking and identification of various targets, and accordingly the device can be widely used in the fields of national economy and national security. |
