System for scanning probe microscope input device
View Patent ↗In accordance with the invention, a computer pointing device is interfaced with an SPM system to provide real time control of the SPM and improve the ease of use.
1. A system for controlling a scanning probe microscope having a scanning probe tip operable to scan a sample surface in real time comprising:
a scanning probe microscope controller that controls the operation of said scanning probe microscope;
a central processing unit in bidirectional communication with said scanning probe microscope controller; and
a pointing device in communication with said scanning probe microscope controller,
said pointing device providing input to said system, said input enabling active control of said scanning probe microscope in real time, wherein said active control includes real time motion control of said scanning of said sample surface, wherein said pointing device provides tactile feedback.
2. The system of claim 1 wherein said central processing unit is part of a personal computer.
3. The system of claim 1 wherein said pointing device is in direct communication with said central processing unit.
4. The system of claim 3 wherein said direct communication is bidirectional.
5. The system of claim 1 wherein said pointing device is in direct communication with said scanning probe microscope controller.
6. The system of claim 5 wherein said direct communication is bidirectional.
7. The system of claim 1 wherein said central processing unit is integrated with said scanning probe microscope controller.
8. The system of claim 1 further comprising a keyboard in direct communication with said central processing unit.
9. The system of claim 8 wherein said communication is bidirectional.
10. The system of claim 8 wherein said pointing device is in direct bidirectional communication with said keyboard.
11. The system of claim 1 wherein said pointing device is selected from a group consisting of a game pad, a joystick, a computer mouse, an isometric joystick, a computer touch screen, a scroll wheel and a wearable pointing device.
12. The system of claim 1 wherein said pointing device comprises a vibration feedback capability.
13. The system of claim 12 wherein said vibration feedback capability is enabled to provide feedback on local forces resulting from the interaction of a scanning probe tip of said scanning probe microscope with a sample surface.
14. The system of claim 12 wherein a level of said vibration feedback capability corresponds to a scanning probe measurement.
15. The system of claim 1 wherein said pointing device comprises action controls that are color coded.
16. The system of claim 1 wherein said scanning probe microscope is a high speed scanning probe microscope.
17. The system of claim 1 wherein said pointing device is used to enable the application of a specific predetermined series of discrete voltage pulses to a sample surface by said surface scanning probe microscope in response to a single input to said pointing device by a user of said microscope.
18. The system of claim 1 wherein a first control of said pointing device is enabled to control movement in an x-y plane while a second control of said pointing device is enabled to control movement in a y-z plane.
19. The system of claim 1 wherein image data derived from a first surface scan generated by said scanning probe microscope are used to control said scanning probe tip of said scanning probe microscope in performance of a second surface scan.
