Abstract (en)
[origin: WO2020053433A1] The invention relates to a method (800) for off-axis transmission digital holographic imaging of an object, comprising the following steps: acquisition (802) of a holographic image of the object (102), comprising the steps of illuminating (804) the object with at least three non-coplanar illumination waves (OI), focussing each object wave from the object towards a digital sensor (126) using a focussing means (122), and detecting (806) an interference figure (126) between the object waves (OI) and a reference wave (OR); and digital reconstruction (808) of a holographic image from the at last one interference figure. The invention also relates to a holographic imaging microscope and assembly implementing such a method.
