Key Points

Enhanced imaging capabilities were demonstrated using an array of superconducting nanowire single photon detectors (SNSPDs).
The system successfully enabled two-photon imaging in the shortwave infrared range, improving visualization.
In vivo imaging of mouse brain vasculature was achieved, showcasing the system's application in biological research.
This technology highlights potential advancements in imaging techniques for neurobiology and other fields.

Implication

Engineering a SNSPD array improved imaging of mouse brain vasculature, suggesting advancements in two-photon imaging techniques.

Abstract

We engineered a free-space coupled SNSPD array for in vivo imaging of mouse brain vasculature using two-photon excitation, with both excitation and emission occurring in the shortwave infrared (SWIR) range for enhanced imaging capabilities.
