The system is configured for performing scanning electrochemical microscopy via non-local continuous line probes. The continuous line probes include an insulating probe substrate, an insulating layer, and a conductive band electrode. The system includes a sample stage for positioning a sample substrate to be imaged so as to enable contact with the insulting probe substrate at an angle &#x398;. The continuous line probe is translated across the sample substrate and changes in the signal generated at the continuous line probe are identified to indicate the presence of features on the sample substrate. A plurality of scans are performed at different angles via rotating the sample stage or the continuous line probe, the results of which are combined and analyzed to produce an image of the sample substrate via compressed sensing reconstruction. The resulting image has comparable resolution to those produced via conventional scanning electrochemical microscopy processes, but in less scan time and with less complex scanning hardware.
