The method is remarkable in that it comprises applying a shift correction parameter on shifted and summed images from said 4D raw light field data, said shifted and summed images being defined as a function of said given focus (z focus ), and said shift correction parameter(Δ) comprising, for at least a part of pixels of at least two sub-aperture images derived from at least one 4D light field data of a test-chart image, determined shifts for pixels belonging to said part of pixels between said at least two sub-aperture images, said test-chart image comprising patterns adequate to compute disparities between said sub-apertures images.

摘要： Methods and apparatus for estimating a depth of unfocused plenoptic data are suggested. The method includes: determining a level of homogeneity of micro-lens images of unfocused plenoptic data; determining pixels of the micro-lens images of the unfocused plenoptic data which either have disparities equal to zero or belong to homogeneous areas as a function of the calculated level of homogeneity of the micro-lens images of the unfocused plenoptic data; and estimating the depth of the unfocused plenoptic data by a disparity estimation without considering the determined pixels. With the disclosure, by pre-processing the raw data, it can prevent any disparity estimation method to spend time on estimating disparities for: (i) pixels that are in focus, (ii) pixels that belong to homogenous areas of the scene.

摘要： Le dispositif est basé sur le principe de Wheatstone. Des miroirs (M1, M2, M3 M4) sont ajustés angulairement pour que les images stéréoscopiques droite et gauche d'une scène soient formées sur un capteur de manière à laisser libre une zone (IR) entre ces deux images. Une fente est formée entre les miroirs internes pour laisser passer, d'une part, une lumière structurée ou impulsionnelle et, d'autre part, cette lumière structurée ou impulsionnelle une fois qu'elle a été réfléchie sur des objets de la scène. Le dispositif comporte, de plus, une optique (AL) associée à la fente (F) et au système de lentilles (SL) pour former une image sur ladite zone (IR) à partir de ladite lumière structurée ou impulsionnelle réfléchie.

摘要： An optical manipulation apparatus for trapping or moving micro or nanoparticles is proposed. Such apparatus comprises a device comprising:
- a first (101) and a second (102) part having respectively a second n 2 and third n 3 refractive index and a first W 1 and second W 2 ;
- a first contact area (100e1) intended to be between a host medium having a first refractive index n 1 and in which the micro or nanoparticles are intended to be trapped or moved by a focused electromagnetic beam radiated by the device;
- a second contact area (100e2) between the first part and the second part; and
- a third contact area (100e3) intended to be between the second part and the host medium.
The focused electromagnetic beam results from a combination of at least two beams among a first (NJ1), a second (NJ2) and a third (NJ3) jet beams radiated respectively by the first, second and third contact areas when an incoming electromagnetic wave (IEM) illuminates the device. The device is configured for having a direction of propagation of the focused electromagnetic beam tilted in respect of a direction of propagation of the incoming electromagnetic wave as a function of the first n 1 , second n 2 and third n 3 refractive indexes; of the first W 1 and second W 2 widths; and of the first H1 and second H2 heights of the first and second parts.
