Thermal Sight: A Position-Sensitive Detector for a Pinpoint Heat Spot.

ABSTRACT: Precise positioning is a never-ending goal in both fundamental science and technology. Recent decades of advancements in high-precision position detection have predominantly relied on photoelectric effects for light detection in semiconductors. Herein, a different approach is proposed: The thermoelectric-based position-sensitive detector (T-PSD) concept is designed to detect single heat spots arising from various energy sources, including electromagnetic radiation, electrons, and macroscopic mechanical heat. The T-PSD concept is initially derived mathematically from the fundamental principles of heat conduction and the Seebeck effect. Subsequently, it is proved by finite element simulation in both 1D and 2D configurations. Following this theoretical groundwork, T-PSD prototypes are fabrica
