DeepView: a channel for distributed microscopy

摘要

The paper outlines the requirements, architecture, and design of a“Microscopy Channel” over the wide area network. Amicroscopy channel has a listing of available online microscopes, whereusers can seamlessly participate in an experiment, acquire expertopinions, collect and process data, and store it in their electronicnotebook. The proposed channel is a collaborative problem solvingenvironment (PSE) that leverages existing computational toolkits tosupport simulation and inverse problem solving. Our testbed includesseveral unique electron and optical microscopes with applicationsranging from material science to biology. We have studied currentcommercial services from OMG and concluded that three basic services areneeded to meet the scalability and functionality constraints. Theseinclude: Instrument Services (IS), Exchange Services (ES), andComputational Services (CS). These services sit on top of CORBA and itsenabling services (naming, trading, security, and notification). ISprovide a layer of abstraction for controlling any type of microscope.ES provide a common set of utilities for information management andtransaction. CS provide the analytical capabilities needed for onlinemicroscopy. The enabling services provide a mechanism for resourcediscovery, safety and security, and decoupled communication
