Synthesis of Silicon-Substituted Hemicyanines for Multimodal SWIR Imaging [PDF]

open access: yesOrganic Letters, 2022
SWIR dyes offer many advantages over their more common NIR congeners; however, the available options are limited. New SWIR imaging agents can be accessed by remodeling existing NIR molecules (i.e., hemicyanines (HDs)). In this study, we synthesized SWIR-HD, a modified HD featuring dimethylsilicon and benzo[cd]indolium groups that are designed to red ...

High-Performance Enhancement of SWIR Images

open access: yesElectronics, 2022
Short-wave infrared imaging technology has rapidly developed over the past decade. However, image detail and contrast enhancement techniques, which are crucial for infrared imaging systems, are rarely dedicated to SWIR imaging systems. Moreover, the existing IR image enhancement methods generally have difficulty providing real-time performance, which ...
