Abstract (en)

[origin: US11256032B1] A programmable fiber-optic delay line simulates spatial distances for an environment sensor. The programmable fiber-optic delay line comprises: at least three optical transfer switches interconnected by a plurality of lengths of optical fiber, wherein the at least three optical transfer switches with the plurality of lengths of optical fiber are configured to provide a continuous delay line having a plurality of different selectable delay values, wherein the different delay values are selectable based on switch positions of the at least three optical transfer switches. A first terminal of a first optical transfer switch of the at least three optical transfer switches is connected to a third optical transfer switch of the at least three optical transfer switches, enabling bypassing of a second optical transfer switch of the at least three optical transfer switches.
