The sample to be analysed is examined in a first field, of low resolution, of the apparatus; if an object thus detected belongs to a specified category, for example the category of leucocytes in the case of a blood sample, it is subjected to a second analysis in a second field, of higher resolution, the low-resolution examination being nevertheless continued in order to detect the possible presence of another object. The apparatus comprises a sample holder (1) which can be moved in two directions using motors (2 and 3), and which holds a sample (4) comprising several particles (5a, 5b, 5c) of interest. An objective (6) forms an image (10) of a part (7) of the sample on a low-resolution sensor (9), and does this using a plate (6b) and an optical system (8), and an image (14) of a part (11) of the sample on a high-resolution sensor (13), and does this using a second optical system (12). The output signal from the low-resolution sensor (9) is analysed so that when a particle of interest is encountered, the sample holder is moved in order to bring the particle into the field of view of the high-resolution sensor, which allows its high-resolution analysis by a corresponding analyser (37). This method and this apparatus make it possible to analyse in detail only the objects of interest, without having to perform a detailed analysis of all the objects present. This method and this apparatus may be used for analysing blood cells, scrapings or cancer cells. <IMAGE>
