    摘要:

    为了克服目前利用短波红外焦平面器件获取图像时难以消除器件自身的非均匀性、难以获得较高信噪比及成本昂贵的问题, 提出了利用单元探测器和DMD(Digital Micro-mirror Device)空间光调制器件, 基于Hadamard变换进行凝视光学画幅式成像的方法.通过实验验证了该方法用于短波红外成像的可行性.对实现低成本、高信噪比的短波红外成像具有借鉴意义.

    Abstract:

    Short-wavelength infrared(SWIR)focal plane array detector suffers from problems including intrinsic non-uniformity, low signal-to-noise ratio(SNR), and relatively high cost. To overcome these difficulties, a staring-mode frame imaging scheme was proposed based on Hadamard transform(HT), using single element detector and digital micro-mirror device(DMD)spatial light modulator. Experimental study has been carried out to verify the validity of this method in SWIR imaging. The results demonstrate that this scheme is a promising approach to achieving low cost, high SNR SWIR imaging.
