[LSC4-04] Two-wavelength excitation near-infrared imaging with upconversion in Er3+

*Yugo Akabe¹ (1. Osaka University)

In recent years, demand for imaging cameras in the near-infrared region has increased with the spread of self-driving cars and drones. On the other hand, existing near-infrared imaging cameras are complicated and expensive. In this study, we developed a simpler near-infrared imaging system using up-conversion in Er3+.
