Definitions

TITLE Optical angular filter
One embodiment provides an angular filter for an image acquisition device comprising a stack comprising: a layer comprising media of different refractive indices and transparent to said radiation, the layer allowing only the rays of said radiation to pass whose incidences are less than a first maximum incidence; and a matrix of apertures delimited by walls opaque to visible and/or infrared radiation and an array of microlenses, the assembly formed by the array of apertures and the array of microlenses allowing only the rays of said radiation to pass whose incidences are less than a second maximum incidence less than the first maximum incidence.
the layer is an interference filter.
the layer comprises a group of optical fibers.
the layer comprises a group of parallel optical fibers each surrounded by an opaque material.
the layer is located between the network of microlenses and the matrix.
the matrix is located between the network of microlenses and the layer.
the device 13 and the processing unit 15 are preferably connected by a connection 17.
the device 13 and the processing unit 15 are, for example, integrated in the same circuit.
Figure 6 illustrates another embodiment of an image acquisition device 65.
FIG. 6 illustrates an image acquisition device 65 similar to the device 19 illustrated in FIG. 2 with the difference that the layer 41 is a structured layer and located between the array of microlenses 29 and the matrix 31.
no opaque layer extends above layer 41.
the layer 41 comprises only transparent materials which, there Tl again, makes it possible to maximize the useful surface of collection of light by the angular filter
