Abstract

In this study, we introduce a technique for creating 3D speckle patterns, which can be utilized in photoluminescence tomography based the single-pixel camera technique. Initially, we showcase our capability to generate independent speckle patterns at different planes near the focal plane, facilitating z-axis resolution imaging. Using simulated data, we explored the effects of various factors and, informed by these analyses, developed an experimental setup capable of producing 3D speckle patterns in reality. Our results indicate that by precisely adjusting the phase distribution of the input field, we can reproduce the 3D patterns with the level of simulation-experiment correlation exceeding 0.9. We further demonstrate the application of actual 3D speckle patterns in 3D photoluminescence tomography using a single-pixel camera and discuss its promise for investigating defects in optical materials.
