Abstract
Sparse sampling approaches and probe systems for analytical instruments are disclosed providing for effective sub-sampling of a specimen and inpainting to reconstruct representations of actual information. The sub-sampling involves serial acquisition of contiguous measured values lying at positions along a scan path extending in a line toward a first direction and having random perturbations in a second direction. The perturbations are limited within a predetermined distance from the line. Inpainting techniques are utilized among the measured values to reconstruct a representation of actual information regarding the specimen.
Claims26
A method for sparse sampling with an analytical probe, the method comprising:
- a) acquiring in a serial mode a plurality of contiguous measured values lying at positions along a scan path extending in a line toward a first direction and having random perturbations in a second direction, wherein the random perturbations are limited within a predetermined distance from the line;
- and
- b) inpainting among the measured values and reconstructing a representation of actual information.
A sparse sampling analytical probe system comprising:
- a) a scanner configured to move a sample and an analytical probe relative to one another and to scan the analytical probe over the sample along a scan path extending in a line toward a first direction and having random perturbations in a second direction, wherein the random perturbations are limited within a predetermined distance from the line;
- b) a detector configured to acquire in a serial mode a plurality of contiguous measured values lying at positions along the scan path;
- and
- c) a processor configured to apply inpainting techniques based on the measured values and to reconstruct a representation of actual information.
