A multi-order diffractive Fresnel lens (MOD-DFL) that is suitable for use in a space telescope for studying transiting earth-like planets of distant stars is provided. The MOD-DFL may comprise a MOD-DFL array comprising a plurality of MOD-DFL segments that are secured to a mounting surface of a deployment device, such as a balloon, for example, in a preselected arrangement to form the MOD-DFL. An array telescope may be formed of an array of deployment devices, such as an array of balloons, for example, each having a MOD-DFL secured to a mounting surface of the respective deployment device, an optics system disposed inside of the respective deployment device, and a camera disposed inside of the respective deployment device. Each MOD-DFL comprises a plurality of MOD-DFL segments arranged in a preselected arrangement to form the respective MOD-DFL.

Multi-order diffractive Fresnel lens (MOD-DFL) and systems that incorporate the MOD-DFL

An optical device is provided that comprises a multi-order diffractive Fresnel lens (MOD-DFL) and an achromatizing compensation mechanism that reduces refractive dispersion created by the MOD-DFL, thereby reducing the focal range of the MOD-DFL. A method is also provided of using the optical device in an image processing system to obtain images of an object and processing the images to perform image enhancement.

A method for territorial filtering, streaming, and downloading media files over a client-server network with local read-write execution capabilities enables application of digital rights management data across batches of media files without admin having to alter each file, or metadata associated with each file, individually. Media files stored remotely in memory associated with a server are batch-handled for application of digital rights management data. Digital rights management data is applicable to batched files by assignation to particular directories wherein media files stored within a particular directory are associable with particular digital rights management data. Territorial filtering is applied to exclude media files from display as part of a selectable menu whereby users requesting access from certain locations are denied access to media files restricted from playback in that location. Media files transferred to user peripheral devices for offline playback are automatically deleted when an associated end time is clocked.
