Femtosecond laser textured porous nanowire structured glass for enhanced thermal imaging

Infrared (IR) thermal imaging has aroused great interest due to its wide application in medical, scientific, and military fields. Most reported approaches for regulating radiation are aimed realize IR camouflage not applicable enhance imaging. Here, we introduce a simple effective method process porous glass by femtosecond laser scanning, where distributed nanocavities nanowires were produced, which caused improvement of the treated emissivity. The as-prepared sample possessed better performance but lower transmittance visible light. We also demonstrated applicability placing it different backgrounds, image temperature laser-treated was closer actual environment, this strategy may provide new vision enhanced
