The application relates to the fields of optics and fire rescue, and discloses a fluorescent conversion sheet with wavelength conversion function and a handheld smoke penetration imaging device. The fluorescent conversion sheet comprises, in sequence, a heat dissipation substrate layer, a mirror layer, a photonic crystal layer and a core-shell structure fluorescent layer. After short-wave near-infrared laser is incident, the core-shell structure fluorescent layer performs wavelength conversion; the mirror layer and the photonic crystal layer form an optical micro resonant cavity, and the unconverted laser is reflected back to the fluorescent layer for secondary conversion; and the heat dissipation substrate layer effectively suppresses the thermal quenching effect. The imaging device utilizes the fluorescent conversion sheet to efficiently convert the easily obtained short-wave near-infrared laser into middle-wave near-infrared laser with strong smoke penetration capability and safety to human eyes and emits the middle-wave near-infrared laser, and a receiving device containing a polarizer is used to image the target echo. Through systematic and synergistic optimization design, the conversion efficiency and thermal stability are greatly improved, excellent smoke penetration imaging effect is realized, and the safety and efficiency of fire rescue are improved.
