An all-passive upconversion system converts incoherent NIR light at ~10^-7 W/cm^2 to visible light with imaging resolution around 100 lp/mm.
Our all-passive imaging system requires no input power, either electrical or via optical pumping, and works with incoherent NIR input light over the range of 700 – 930 nm

All-passive upconversion of incoherent near-infrared light at intensities down to 10$^{-7}$ W/cm$^2$
An all-passive upconversion system converts incoherent NIR light at ~10^-7 W/cm^2 to visible light with imaging resolution around 100 lp/mm.
