Hyperspectral imaging with a liquid crystal polarization interferometer
A novel hyperspectral imaging system has been developed that takes advantage of the tunable path delay between orthogonal polarization states of a liquid crystal variable retarder.
-
Printed dose-recording tag based on organic complementary circuits and ferroelectric nonvolatile memories
We have demonstrated a printed electronic tag that monitors time-integrated sensor signals and writes to nonvolatile memories for later readout.
