Digital holographic microscope

Microscope comprising:

• a light source producing a light beam,
• a light beam guide system comprising
• a beam splitter configured to split the light beam into a reference beam and a sample illumination beam passing through the light beam guide system directed by at least one direction change mirror being pivotally actionable (TM1, TM2, TM3, TM4) to guide the reference beam and sample beam along their respective optical paths,
• a sample observation zone configured to receive a sample to be observed in a path of the sample illumination beam,
• a beam reuniter configured to reunite the reference beam and sample illumination beam after passage of the sample illumination beam through the sample observation zone,
• a light sensing system configured to retrieve at least phase and intensity values of the light beam downstream of the beam reuniter, and
• a control system,
• wherein the control system is configured to generate a mirror angle control signal to automatically control an angle of said at least one pivotally actionable direction change mirror, the mirror angle control signal being based at least partially on a signal received, by means of a feedback loop of the control system, from the light sensing system and generated by the light beam.
