HTCC-based photon power supply measurement module and large light spot test system

The invention belongs to the technical field of photoelectric measurement, and provides an HTCC-based photon power supply measurement module, which comprises a photon power supply, a processor unit, a wireless transmitting module and a wired interface module. The photon power supply measuring module adopts an HTCC packaging laser battery structure, and is high in heat conductivity, resistant to high temperature and wide in adaptable working laser power density range; a selective permeable membrane is arranged, wavelength selection can be carried out, and the influence of other stray light is eliminated; the laser intensity is measured based on the photoelectric conversion characteristic of the laser cell, the temperature of the photon power supply is measured by using the thermistor on the back of the HTCC ceramic substrate, and the measurement accuracy is high. According to the large light spot test system, a plurality of photon power supply measurement modules are adopted to form a distributed array, the si
