A search for a target in a multispectral image is made more efficient and more user-friendly by combining a contrast optimization which is performed locally, with a presentation of a detection image which extends over the entire field of observation (). The contrast is optimized inside a window () of reduced size relative to an image matrix () corresponding to the entire field of observation. This window may be moved in conjunction with the direction of observation (D), or it may be selected at will in the image matrix. The detection image may be renewed for each window used, or it may be shared by several windows.

The invention relates to a high-resolution imaging system for recording images of the same scene, that are sampled in a complementary manner. To this end, an image filter () is arranged in an intermediate focusing plane (PI), and a matrix () of microlenses is arranged at a distance from the image filter, with each microlens that is associated with an opening (O) of the image filter. An image detection matrix () is then optically conjugated with the microlens matrix. The system also comprises a device for moving an intermediate image in relation to the image filter (). Such an imaging system is especially suitable for recording high-resolution infrared images.

High-resolution imaging system

An engine and pod assembly for an aircraft includes a pod receiving an engine having an air intake. A rotating nose cone extends on the nose cone, as well as a device for limiting the formation of ice. The device includes means for creating a circumferential heterogeneity of ice on the nose cone.
