Digital holographic microscopy

Digital holographic microscopy (DHM) is digital holography applied to microscopy. Digital holographic microscopy distinguishes itself from other microscopy methods by not recording the projected image of the object. Instead, the light wave front information originating from the object is digitally recorded as a hologram, from which a computer calculates the object image by using a numerical reconstruction algorithm. The image forming lens in traditional microscopy is thus replaced by a computer algorithm.

Holographie

L'holographie est un procédé d'enregistrement de la phase et de l'amplitude de l'onde diffractée par un objet. Ce procédé d'enregistrement permet de restituer ultérieurement une image en trois dimensions de l'objet. Ceci est réalisé en utilisant les propriétés de la lumière cohérente issue des lasers. Le mot « holographie » vient du grec holos (« en entier ») et graphein (« écrire »). Holographie signifie donc « tout représenter ».

Indice de réfraction

vignette|Image des fronts d'onde émis par une source ponctuelle mettant en évidence le phénomène de réfraction. La zone inférieure située sous la ligne grise a un plus grand indice de réfraction et donc une vitesse de propagation proportionnellement inférieure à celle de la zone supérieure (pour une raison de clarté, la réflexion partielle n'est pas montrée).
