AI Technical Summary
Existing reflectivity thermal imaging technology, under oil immersion imaging conditions, cannot simultaneously consider the stability of the reference state, oil temperature changes, and oil immersion parameter drift, resulting in unstable or locally distorted temperature distribution field inversion results.
An optical detection module, an oil immersion module, and an oil temperature sensing module are used to acquire reflected light signals and the temperature of the oil immersion medium. Combined with a control processing module, reference correction, oil immersion parameter compensation, and physical constraint iteration are performed. The temperature distribution field is output using a physical information variational model.
It improves the stability and reliability of the temperature distribution field on the surface of the sample under test, and reduces the impact of oil film disturbance and local reflection anomalies on the temperature field output.
