An imaging device includes light sensitive locations that are separately sensitive to light received at a surface with respect to a portion of a sample associated with the surface, the light sensitive locations having a resolution of 5 microns or smaller. There is a device to associate the portion of the sample with the surface. The imaging device and a distance of the portion of the sample to the light sensitive locations are such that usable useful image of the portion of the sample can be acquired directly by operation of the imaging device. An imaging device includes light sensitive sources that are separately able to deliver light with respect to a portion of a sample associated with the surface. The light source locations having a resolution of 5 microns or smaller. There is a device to associate the portion of the sample with the surface. The imaging device and a distance of the portion of the sample to the light source locations are such that a useful image of the portion of the sample can be acquired directly by operation of the imaging device. An imaging device can include both the light source locations and the light source locations and the light sensitive locations.L'invention concerne un dispositif d'imagerie comprenant des endroits photosensibles qui sont séparément sensibles à la lumière reçue au niveau d'une surface par rapport à une partie d'un échantillon associé à la surface, les endroits photosensibles ayant une résolution de 5 micromètres ou moins. L'invention concerne également un dispositif pour associer la partie de l'échantillon à la surface. Le dispositif d'imagerie et une distance entre la partie de l'échantillon et les endroits photosensibles sont de sorte que l'image utile utilisable de la partie de l'échantillon peut être obtenue directement par le fonctionnement du dispositif d'imagerie. Un dispositif d'imagerie comprend des sources photosensibles qui sont apte à diffuser séparément de la lumière par rapport à une partie d'un échantil
