This study presents a laser scanning system for macroscopic samples that can record fully resolved decay curves and images at multiple laser wavelengths. The system utilizes confocal detection to eliminate lateral scattering and out-of-focus haze. The system's performance is demonstrated on model experiments and a tumor model in living mice.
We present a laser scanning system for macroscopic samples that records fully resolved decay curves in individual pixels, resolves the images in 16 wavelength channels, and records simultaneously at several laser wavelengths. By using confocal detection, the system delivers images that are virtually free of lateral scattering and out-of-focus haze. Image formats can be up to 256 x 256 pixels and up to 1024 time channels. We demonstrate the performance of the system both on model experiments with fluorescent micro-beads and on the tumor model in the living mice. (c) 2023 Optica Publishing Group
