Abstract

The invention relates to a method for observing a sample (15), comprising the illumination of the sample using a light source (11) and the acquisition of an image (Io) of the sample using an image sensor (16), the sample being disposed between the image sensor and the light source. Iterative steps are applied to the acquired image (Io), also referred to as a hologram, comprising: a single iterative numerical propagation (h), such as to estimate a complex image (A) of the sample in a reconstruction plane (P10) or in a detection plane (P0), in which the image sensor extends. The complex image can be used for the characterisation of the sample.
