Nowadays, the demand for non-destructive testing is increasing, leading to a growing focus on the testing of objects. In the case of low unit price testing objects such as polymer materials, cost-effectiveness, quickness, and non-invasiveness are crucial considerations for the approaches.
The non-invasive tomographic system that we have proposed is capable of imaging tomography by utilizing back-scattered light from deep inside the object and directly imaging deep-scattered light. In this study, our purpose is to apply this system to opaque media, using a continuous-wave laser light source in the near-infrared spectrum (wavelength 1550 nm). This wavelength exhibits a high transmission rate through polymer materials, allowing the incident light to propagate deeper into the media. This characteristic enables the imaging of tomography for hard-scattering media and is expected to facilitate tomography for even more opaque media.
