Digital in-line Holography applied to fluid mechanics measurements

Montage en ligne ; In-line setup

Optical arrangement consisting in placing the light source and the sensor opposite each other.

Reconstruction numérique; Numerical or digital Reconstruction

A step in the digital processing of holograms, which consists in reconstructing the holographic objects.

Restitution; Reconstruction

Restitution (of a hologram) only concerns optical holography. It consists in re-illuminating the hologram with the illumination wave. Diffraction of the hologram is called "restitution" because it restores the object wave.

Propagator ; Propagateur

In holography, a propagator is a mathematical operator used to computationally simulate the propagation of light.

Impulse response or Point Spread Function

The impulse response of an imaging system is the image obtained when the object is a point (a spatial impulse δ). In our...
