摘要： An optical device and systems for near and distance imaging includes an optical unit with a first optical lens and a second optical lens, the first optical lens and second optical lens being arranged along an optical axis, and a transceiver unit with a transceiver element, a light passage surface of the transceiver element being arranged in or intersecting a plane or curved surface. A first distance between the surface and the first optical lens is provided along the optical axis and set in such a way that, during intended normal operation, the transceiver element of the transceiver unit is imaged onto a distant imaging surface by the optical unit.

摘要： A system for optical communication includes at least one light source for transmitting optical signals, at least one optical receiving unit for receiving the optical signals of the at least one light source, at least one mask unit, which is arranged between the optical receiving unit and the at least one light source, and which is designed to be switchable back-and-forth at least in areas between an at least partially optically non-forwarding and at least partially optically forwarding state. An image of at least one light-emitting area of the at least one light source can be imaged onto the at least one mask unit and in the at least partially forwarding state of the at least one mask unit can be conducted to the receiving unit. A method for optical communication is also provided.
