Locations of the origins of the photons are acquired from a scanned sample with reference to a scan frame. The location on the sample from which a photon was emitted is inferred from the location of the scan as commanded by a scan drive signal, a feedback signal related to the position of the scan device, or alternatively by the point in time during a scan at which the photon is detected. A position function, e.g., photon probability density, is associated with a photon position. Summing or other processing of photon probability density functions can require fewer photons to converge to an ideal density distribution associated with an image feature than are required using conventional pixel binning. Stored data can be mapped into pixels or voxels of a display or otherwise processed. Original data remains available in the digital storage for post-hoc analysis. Imprecision introduced by the display process need not adversely affect the precision of the collected data.

The invention discloses an SSH protocol operation and maintenance auditing system based on proxy technology. A monitoring playback module is arranged in a proxy server, auditors monitor operation and maintenance sessions between a client side and a target server in real time through the monitoring playback module, and meanwhile the auditors also can play back the finished operation and maintenance sessions according to their requirements. The invention further discloses an SSH protocol operation and maintenance auditing method based on the proxy technology. The functions for command analysis and session monitoring, cut-off and playback in the operating process are achieved when operation and maintenance staff conduct operation and maintenance operation on the target server, and beforehand prevention, current intervention and post analysis and processing of the operation and maintenance operation are achieved. According to the system and method, the internal risk control level of enterprises is increased to a certain degree, the operation and maintenance management level of an information system is increased, user behaviors on the servers are tracked, operation and maintenance cost is reduced, control and audit bases are provided, and the operation and maintenance operation is safer.

The invention relates to the field of power system monitoring, in particular to a method for real-time monitoring of the operating status of power distribution facilities and distribution cable lines, to realize early warning, alarm and post-event analysis of abnormal and fault states, and to control and adjust the operation of equipment through remote operation Environmental cable 10kV high-voltage ring network cabinet remote monitoring and control system. The invention aims at the intelligent operation and management of the power grid, integrates various online monitoring technologies, installs monitoring cameras, fans and solar energy equipment in the switching station, and can check the monitoring camera information in the switching station and the monitoring of the operating status of the fan through the system in real time to realize abnormality. Early warning, alarm and post-event analysis of fault status, realize dynamic evaluation of equipment health status, realize remote operation control of monitoring equipment, combine multi-dimensional display technology, strengthen safe and reliable operation ability of distribution network, improve fault finding and maintenance efficiency, A complete set of grid visualization monitoring system has been formed.
