    • A coherent radiation imaging system that produces digital images with a reduced amount of speckle. Radiation from a long coherence length source is used to form an image of a sample. The output coherent wave is temporally divided into a plurality of wavelets. The spatial phase of each wavelet is then modulated a known and different amount. Each phase modulated wavelet illuminates the sample and is perturbed by its interaction with the sample. A spatial phase map of each perturbed wavelet is then created and converted to a sample image with an image reconstruction program. The plurality of sample images thus formed is statistically averaged to form a final averaged image. The high frequency speckle that is not optically resolvable tends to average to zero with continual statistical averaging, leaving only the optically resolvable lower frequency phase information.
    • 相干辐射成像系统,产生数量少的斑点数字图像。 来自长相干长度源的辐射用于形成样品的图像。 输出相干波在时间上分为多个小波。 然后将每个小波的空间相位调制为已知且不同的量。 每个相位调制小波照亮样品,并受到与样品的相互作用的干扰。 然后创建每个扰动小波的空间相位图,并将其转换为具有图像重建程序的样本图像。 如此形成的多个样本图像被统计学地平均以形成最终平均图像。 不能光学解析的高频散斑趋向于平均为零,并且连续的统计平均,仅留下光学可分辨的较低频率相位信息。

    • A method and system for renewing software at the component-level is provided. A client program includes a base component for loading a software component into at least one loadable region of the program to update the program. Code in the software component is for writing state data associating the state of the update in storage, upon execution of the software component, and testing the state data to verify condition of the updated program and disallowing rollback and roll-forward attacks, the state data comprising hash chain values. The state data for verifying the correctness of the updated program is entangled with application data used for the program functionality. A server includes: an update pool having a plurality of software updates deployed in each client, and a policy control for monitoring and controlling at least one of: the length of time the client runs until the software update is invoked, a chain of the updates; and the granularity of the update.
    • 提供了一种在组件级更新软件的方法和系统。 客户端程序包括用于将软件组件加载到程序的至少一个可加载区域中以更新程序的基础组件。 软件组件中的代码用于写入状态数据,将存储器中的更新状态与执行软件组件相关联,并测试状态数据以验证更新程序的状态,并禁止回滚和前滚攻击,状态数据 包括哈希链值。 用于验证更新的程序的正确性的状态数据与用于程序功能的应用程序数据相互纠缠。 服务器包括:具有部署在每个客户端中的多个软件更新的更新池,以及用于监视和控制以下至少之一的策略控制:客户端运行到软件更新被调用的时间长短,更新链 ; 和更新的粒度。
