Atomic force microscopy
 It is also known as scanning force microscopy.
 AFM is a very high resolution type of scanning probe microscopy , with resolution of order of a fraction of nanometer.
 AFM is one of the foremost tools for imaging , measuring and manipulating matter at the nanoscale.
Modes of AFM
There are three modes in which AFM can be operated depending on application:-
1. Static mode (contact).
2. Dynamic mode(non contact).
3. Tapping mode.

Microscope Light Dimmer for Biomedical Image Enhancement with Virtual Instrumentation


I. INTRODUCTION
Light dimming is based on adjusting the voltage
which gets to the lamp. Light dimming has been
possible for many decades by using adjustable power
resistors and adjustable transformers. The problem of
those light controlling methods have been that they
are big, expensive, have poor efficiency and they are
hard to control from remote location.

SEM
Introduction
The optical microscope was invented in the early 17th century. Although this discovery that revolutionized science, these were the first microscopes little more than one type magnifying glasses. The centuries many scientists then looked for new versions of the microscope with an improved resolution. In the year 1900, the maximum resolution achievable with a light microscope reached: 2 micrometers.
This maximum resolution we can do as follows:
The wavelength is important for the resolution on ee optical system, es ....etc

All microscopes which provide images of atoms on or in the surface of any body is called atomic force microscope or the AFM, while all those microscopes which uses the principle of the atomic force microscopes are called as scanning probe microscope or the SPMâ„¢S.
These scanning probe microscopes work by measuring a local property such as height ,optical absorbtion magnetism etc ,by scanning over the sample by measuring the above property and providing the image on the television,with the probe or ....etc

Abstract:
The atomic force microscope (AFM) or scanning force microscope (SFM) is a very high-resolution type of scanning probe microscopy, with demonstrated resolution of fractions of ananometer, more than 1000 times better than the optical diffraction limit. The precursor to the AFM, the scanning tunneling microscope, was developed by Gerd Binnig and Heinrich Rohrer in the early 1980s, a development that earned them the Nobel Prize for Physics in 1986. Binnig,Quate and Gerber invented the first AFM in 1986. The AFM is one of the forem ....etc

The best optical microscopes can see structures in the 200 – 400 nm range, at their limits of resolution.
The STM can “see” structures on the order of 0.1 nm —another SPM, the AFM—can distinguish things on the order of 100 nm .
Optical microscopes are “diffraction limited”—the wavelength range of visible light (400-750 nm) sets the size of the smallest thing that can be imaged: ~ 400 nm.
Scanning Probe Microscopes don’t use visible light—they depend on measuring intermolecular ....etc

The limits of pushing storage density to the atomic scale are explored with a memory that stores a bit by the presence or absence of one silicon atom. These atoms are positioned at lattice sites along self-assembled tracks with a pitch of five atom rows. The memory can be initialized and reformatted by controlled deposition of silicon. The writing process involves the transfer of Si atoms to the tip of a scanning tunnelling microscope. The limits of pushing storage density to the atomic scale are explored with a memory that stores a bit by the ....etc
