Fractioned-pattern radiation mapping, Part II: assessment.

Area of Science:

• Optical Engineering
• Metrology
• Radiometry

Background:

• Theoretical framework for predicting radiation distribution in optical systems was introduced in Part I.
• This framework relies on decomposing emitting source power.
• Experimental validation is crucial for theoretical models in optical engineering.

Purpose of the Study:

• To validate the theoretical method for predicting radiation distribution.
• To demonstrate the practical application of source power decomposition in optical systems.
• To assess the method's performance in both simple and complex optical setups.

Main Methods:

• A radiating source, calibrated for traceability to the candela (SI unit for luminous intensity), was used.
• A single-surface optical system was employed for a practical validation example.
• Numerical simulations were performed for a multi-surface optical system to assess performance.

Main Results:

• The practical example confirmed the validity of the source power decomposition method.
• The numerical example demonstrated the method's capability in a more complex, multi-surface system.
• Traceability to the candela ensures the reliability of the radiation measurements.

Conclusions:

• The source power decomposition method provides a valid approach for predicting radiation distribution in optical systems.
• The method is applicable to both simple (single-surface) and complex (multi-surface) optical designs.
• Experimental and numerical validation confirms the robustness and utility of the proposed theoretical background.
