Integrated optical receiver skin

摘要

A multilayer film or skin for free space optical data transmission includes a first outer layer. The first outer layer has a first laterally extending area that transmits optical data signals received over a range of incident angle. A second layer that includes a second laterally extending area underlies the first layer. At least a portion of the optical data signals received by the second layer from the first outer layer is focused or otherwise concentrated into a substantially reduced area. An optical detector receives the concentrated optical data signals from the second layer. An electrical connection extends from the optical detector to an external receiving device. The multilayer film or skin may be used, for example, in applications involving mobile free space optical communication platforms where low profile, volume and mass and/or enhanced platforms are important.

主权项

1. A multilayer film or skin for free space optical data transmission, comprising:
a first outer layer, which includes a first laterally extending area that transmits optical data signals received over a range of incident angles; and
a second layer that includes a second laterally extending area which underlies the first layer in which at least a portion of the optical data signals received from the first outer layer is concentrated into a substantially reduced area, wherein the second layer only accepts optical data signals from a specific optical collection area that is defined in the second layer, the specific optical collection area being less than an entirety of the second layer; and an optical detector for receiving the concentrated optical data signals from the second layer; and an electrical connection extending from the optical detector to an external receiving device.
