Step-change in radiometry provided by improved predictable quantum efficient detectors
Photonics technologies are key enabling for innovation in many different domains, industry, environment, health, medicine, energy, lighting and science. The photonic industry and standardisation organisations request miniaturised, cost-effective, integrated and self-calibrating measurement systems that cannot be provided by traditional methods. Developments exploiting predictable photodiodes along a decade of joint research projects have demonstrated improved uncertainty to 10 ppm and the proof-of-concept of an NMI-on-a-chip suitable for miniaturisation.
The seminar will review the recent results that has created this step-change in radiometry and the foreseen exploitation of the new detectors as built-in standards in various applications.
