“…7 The combination of infrared spectroscopy with imaging creates outstanding detection capability and recognition ability of desired targets. [8][9][10] Traditional IR combined imaging and spectral-analysis instruments share the same sensor with the spectroscope of prism or grating, [11][12][13][14][15] such as Hyperion, an advanced imaging spectrometer designed and produced for NASA's New Millennium program by SSG Precision Optronics, Inc. 16 defect of prism and grating structure is its sensitivity or namely signal to noise ratio (SNR). Optical narrow bandpass filter spectrometers, 16 such as the SR-5000 Remote Sensing Spectroradiometer of CI Systems, Ltd., are highly sensitive, with its resolution corresponding to the quantity of filters.…”

We present a new optical system for infrared (IR) image-spectrum integration remote sensing. The purpose to develop this instrument is to find the key spectral characteristics of typical hot target and to explore a new intelligence fusion method for the recognition. When mounted on a two-dimensional rotation stage, it can track the suspected target by image processing, and then get its spectrum to do recognition. It is a dual-band system with long-wave infrared (LWIR) imaging and mid-wave infrared (MWIR) spectrum. An IR dichroic beamsplitter is used to divide wideband incident infrared into LWIR and MWIR. Compared to traditional infrared combined imaging and spectral-analysis instruments, it yields higher sensitivity for measuring the IR spectrum. The sensors for imaging and spectrum detection are separate, so high spatial resolution, frame rate, and spectrum resolution can all be obtained simultaneously.
