  • Patent number: 9921102
    Abstract: A moving platform borne infrared image-spectrum associated detection system includes an optical hood, a broadband optical system, a two-dimensional servo system, an infrared optical fiber, a Fourier interference spectrum module, an image-spectrum associated detection processing module, a power supply module, and a display module. Incident light enters from the optical hood to the broadband optical system, and is split by a spectroscope. Transmitted light is focused by a long-wave imaging lens group on an infrared detector for imaging. Reflected light is focused by a broadband spectrum lens group to an optical fiber coupler, enters the Fourier interference spectrum module through the infrared optical fiber to form an interference pattern, and undergoes Fourier transform to obtain spectral data.

  • Patent number: 9651763
    Abstract: The present invention discloses a co-aperture broadband infrared optical system, belonging to the field of infrared optical system. The system realizes long wave infrared (LWIR) imaging and broadband infrared spectrum measurement, and solves the problems of limited optical path layout, large volume and high cost of an optical system. The present invention includes a Cassegrain lens, a spectroscope, a reflector, several lens groups, an FPA interface and an optical fiber interface. Light (2 ?m˜12 ?m) is incident to the Cassegrain lens to be focused, then is split by the spectroscope, where 50% of the LWIR light (8 ?m˜10 ?m) passes through the lens group for aberration correction, and the image plane is focused again at the imaging interface. The other 50% of the LWIR light (8 ?m˜10 ?m) and the infrared reflected light (2 ?m˜8 ?m and 10 ?m˜12 ?m) pass through the lens group, and are reflected by the reflector, then focused at the optical fiber interface.

  • Patent number: 9518867
    Abstract: The invention discloses a detecting device combining images with spectra in an ultra-wide waveband, comprising a scanning rotating mirror, a Cassegrain mirror assembly, three spectroscopes, a reflector, four broadband lens assemblies, a visible and near-infrared lens assembly, a long wave lens assembly, a CCD imaging unit, an FPA imaging unit, a Fourier spectrum measuring unit and a grating spectrum measuring unit. The invention is able to recognize a target accurately by spectrum measurement under the guidance of a preliminary recognition process by imaging in visible, near-infrared and long wave infrared wavebands and can solve the problems of incomplete waveband imaging, restricted optical layout, large device size, and poor ability to detect moving objects and dynamic behaviors in prior art.
