Three new research papers featuring the heliCam – three examples of versatile lock-in imaging

The heliCam is used by research groups worldwide to visualize extremely small signal changes, even under demanding conditions. Three recent publications demonstrate how lock-in imaging enables new pathways in biometrics, quantum sensing, and field/signal imaging. Robust hyperspectral measurement despite ambient light: Remote biometrics (PPG, SpO₂, BP/ECG reconstruction) A team from the University of Wisconsin–Madison presents […]
