本文讨论了作者所提出的白光信息处理系统的基本概念,以及用它在进行复数滤波、信号综合及平行光学处理诸方面的若干研究成果。这种方法既消除了相干系统中不可避免的相干噪声,又保持了相干系统所具有的运算能力。值得指出的是,它还具有相干系统所不具有的独特优点,即由于光源本身的相当广阔范围的光谱分布,对多色信号及彩色图象的处理十分有利和相当有效。它为光学信息处理展示了一个新的具有良好前景的方向。

本文叙述了用廉价的白光光学处理器,通过对多光谱遥感资料的编码进行假彩色合成技术。空间编码是用各种多波段影像透明片进行的,并且通过对波纹状付里叶光谱的彩色滤波得到假彩色。与低分辨率数字影像相比,白光方法产生出高质量的彩色编码产品。由于没有使用相干光源,这种影像就没有相干嗓声。这种简单而多能的技术可供广泛的应用。使用70毫米的黑白负片对三个波段的多波段陆地卫星资料进行处理。在这种假彩色编码影像上可以识别各种地表特征。因为每一专题类别都用不同的颜色表示,所以森林、农业用地、水体,城区和矿带都能在影像上显示出来。

silk damping is well known in the study of cosmic microwave background（CMB） and accounts for suppression of the angular power spectrum of CMB on large angular multipoles. In this article, we study the effect of silk damping on the scalar-induced gravitational waves（sIGWs）. Resulting from the dissipation of cosmic fluid, the silk damping notably suppresses the energydensity spectrum of sIGWs on scales comparable to a diffusion scale at the decoupling time of weakly-interacting particles. the effect offers a novel observable for probing the underlying particle interaction, especially for those mediated by heavy gauge bosons beyond the standard model of particles. We anticipate that pulsar timing arrays are sensitive to gauge bosons with mass ～10～3-10～4 GeV, while space-and ground-based interferometers to those with mass ～10～7-1012GeV, leading to essential complements to on-going and future experiments of high-energy physics.
