The particles may comprise a predetermined diffraction pattern identifier.

Figure 1: Diffraction pattern of a silicon single line.

The imaging device provides a magnified image of the diffraction pattern of the reflected light.

The diffraction behavior allows the location of the atoms to be established.

A diffraction pattern of a crystal is a map of the reciprocal lattice of the crystal.

According to the method, a lens-free imaging device is used to acquire a diffraction figure corresponding to a cell.

Subsequently, the invention comprises determining a light intensity on a central surface (46) of an elementary diffraction figure associated with said cell.

This is the back focal plane of the microscope, and is where the diffraction pattern is formed.

The reflected light may also impinge upon an imaging device to generate a magnified image of the diffraction pattern of the reflected light.

Experimentally, and based on the diffraction pattern obtained, the group determines the total length of the track.

The invention relates to a system (1) for detecting a translation (T) of a body (2) with, a diffraction pattern (3) applied to said body.

The lensless microscope records the diffraction pattern of a laser by the sample (principle of holography), then processes this figure by computer to generate the image.

By manipulating the magnetic lenses of the microscope, the diffraction pattern may be observed by projecting it onto the screen instead of the image.

The diffraction patterns are then analyzed in light of the hypothesized structure, and if it looks plausible that the given structure would produce the observed diffraction pattern, a conclusion is drawn.

The spatial modulation element (103) displays diffracted light, which is diffracted by displaying the composite diffraction pattern, to a user as a virtual image.
