AI Technical Summary
Existing neutron imaging devices lack systematic integration in light-shielding design, heat dissipation design, and collimation geometry adjustment, leading to light leakage and thermal noise problems, which affect imaging quality and flexibility.
A multi-stage light-shielding, temperature-controlled, collimation ratio-adjustable neutron imaging system is designed. By integrating a light-shielding telescopic component, a multi-curve deflector air duct box, and a temperature control component, the system achieves light-shielding design for collimation geometry adjustment and optical path connection area. Combined with heat dissipation design, a compact system structure is formed, blocking external light and reducing thermal noise.
It significantly improves the dark-field purity and thermal stability of neutron imaging, enhances the signal-to-noise ratio and repeatability of weak signal imaging, adapts to different ambient temperatures and light leakage conditions, and strengthens the system's adaptability.
