This method allows for the rapid and precise acquisition of experimental data on light intensity angle distribution, significantly enhancing experimental efficiency compared to traditional measurement methods, while also preventing sample degradation. During the design process of the optical system, key steps include dispersing the light generated by the sample through an objective lens at various angles, and filtering out noise at high angles using an adjustable iris (IRIS). The lens-free components serve as a fundamental setup to adjust and match the size of the light beam, ultimately forming a twodimensional light intensity distribution image of angle against angle on the CCD. The excitation of the sample is achieved through Photoluminescence,enabling the system to flexibly adapt to the excitation needs of various samples.
