Abstract
An optical microscope is adapted for observation of several spots of an object by a modifiable optical transmission screen placed on the path of the optical beam and able to generate in the object plane a screen image coinciding substantially with the spots of the object. The modifiable optical transmission screen can comprise a matrix of mirrors, each of the mirrors presenting a first position enabling the light beam to be reflected to the object along the optical path and a second position enabling the light beam to be diverted from the optical path. Alternatively, the modifiable optical transmission screen can comprise a matrix of liquid crystal elements, each of the liquid crystal elements presenting a first transparent state, a second opaque state and, possibly, a third polarising state. The light source can be a light-emitting diode array.
