DEEM, a versatile platform of FRD measurement for highly multiplexed fibre systems in astronomy
Yunxiang Yan, Qi Yan, Gang Wang +6
We present a new method of DEEM, the direct energy encircling method, for characterising the performance of fibres in most astronomical spectroscopic applications. It's a versatile…

A modified method for determining the FRD and length properties of optical fibres in astronomy
Yunxiang Yan, Gang Wang, Weimin Sun +4
Focal ratio degradation (FRD) is a major contributor to throughput and light loss in a fibre spectroscopic telescope system. We combine the guided mode theory in geometric optics a…
