Patent ID: 11652618

Abstract:
An imaging and quantum cryptography apparatus comprising alight-refracting optical setup (101), a light-directing optical setup (102), an imaging sensor (103) capturing light refracted from the light-refracting optical setup and directed to the imaging sensor by the light-directing optical setup and at least one of a quantum key distribution (QKD) transmitter (104) generating a QKD light signal and transmitting the QKD light signal via the light-directing optical setup and through the light-refracting optical setup and a QKD receiver (105) acquiring and decoding light signals refracted from the light-refracting optical setup and directed to the QKD receiver by the light-directing optical setup. The imaging sensor, the at least one of QKD transmitter and QKD receiver, and the alignment unit, all use the same light-directing optical setup and the same light-refracting optical setup.
