G-mode Controller and Software for Scanning Probe Microscopy

General mode (G-Mode) atomic force microscopy is based on information-theory analysis of the direct data stream coming from the microscope photodetector. It allows for full exploration of complex tip-sample interaction reconstruction into mapping of multidimensional material properties.
Specifications:
- Frequency bandwidth: Hz-MHz
- LabVIEW software controls the gathering and saving of full photodiode data stream at 4MS/s.
- Compatible with all AFM platforms.
Applications:
Increasing the temporal resolution of electrical AFM modes such as Kelvin Probe force microscopy down to the µs time scale (has been applied to solar materials and polymers)
Allowing AI/ML analysis technique to work on big data type microscopy datasets in all spatio-temporal dimensions overcoming classical lock-in and phase locked loop processing.
