Electronics and data acquisition demonstrator for a kinetic inductance camera

Understand

A prototype of digital frequency multiplexing electronics allowing the real time monitoring of kinetic inductance detector (KIDs) arrays for mm-wave astronomy has been developed.

• It requires only 2 coaxial cables for instrumenting a large array.
• For that, an excitation comb of frequencies is generated and fed through the detector.
• The direct frequency synthesis and the data acquisition relies heavily on a large FPGA using parallelized and pipelined processing.
