【摘要】 传统成像大都基于透镜成像原理,成像结果严重依赖于探测器质量。特别是对于红外成像,通常采取提高探测器阵列密度即减小像元尺寸的方法来提高成像分辨率,这样反而会导致光通量降低,噪声相对水平提高,也增加了制造成本。除经典成像外,目前存在一种反常的间接成像方式是关联成像,或称鬼成像。提出将关联成像应用于红外成像探测,搭建基于近红外光源的计算关联成像系统,只需使用一个无空间分辨能力的探测器就能完成成像,避免了光通量在维度上的分配,降低了探测难度和成本。更多还原

【Abstract】 Traditional imaging are mostly based on the principle of lens imaging which is simple but the imaging result is heavily dependent on the quality of detector. It is usual to increase the detector array density or reduce the size of pixels to improve the imaging resolution, especially for infrared imaging. It will decrease the light flux causing the noise enhance relatively and add the cost on the contrary. Besides,there is a novel imaging technology called ghost imaging. We present a new infrared imaging method named computational ghost imaging only using a bucket detector without spatial resolution, which avoiding the allocation of flux on the pixel dimension as well as reducing the cost.更多还原
