Understanding the mechanisms of interaction between bone/bone marrow, circulatory system and nervous system is of great interest due to the potential clinical impact. In humans, the amount of knowledge in this domain remains relatively limited due to the extreme difficulty to monitor these tissues continuously, noninvasively and for long or repeated periods of time. A typical difficult task would be, for example, to continuously monitor bone/bone marrow blood perfusion, hemoglobin oxygen saturation or blood volume and study their dependence on the activity of the autonomic nervous system. In this review article, we want to show that nearinfrared light might be utilized to solve these problems in part. We hope that the present analysis will stimulate future studies in this domain, for which near-infrared light appears as the best available technology today.

在航天相机的成像过程中,拍摄场景的亮度随着地表目标和大气环境的变化而发生改变,为了保证航天相机输出理想的图像,提出了基于地-气间辐射模型的航天相机自动调光方法。根据地-气间辐射传输特性建立航天相机入瞳处辐照度模型,通过分析大气气溶胶对遥感成像的影响,对该模型进行了改进,并在此基础上提出了航天相机自动调光方法。航天相机自动调光首先根据总辐照度以及地面目标辐照度占总辐照度的比例对自动调光参数进行调节,目的是尽可能提高地面目标信息量,然后根据大气气溶胶光学厚度确定自适应拉普拉斯滤波的参数,增强遥感图像的细节。由
