Gramian angular field encoding enabled ultra-wide-range cryogenic temperature sensing by deep learning.
An interferometric cryogenic temperature sensor, featuring anti-electromagnetic interference and chemical corrosion resistance, provides increasing opportunities for precise monitoring in spacecraft, biomedicine, and cryobiology. However, in existing sensing systems operating over a wide dynamic range, spectral overlap...
