Question

Which microscope has working principle most similar to the way a blind person reads?

Answer 1

The Atomic Force Microscopes has working principle most similar to the way a blind person reads.

The atomic force microscope (AFM) can be referred as the kind of the SPM (scanning probe microscopes).

The SPM is generally designed for measuring the local properties, i.e. height, magnetism, friction with a probe.

The SPM must raster-scan that probe to acquire the image over any small area of sample.
