Compressed sensing (CS) is a technique to reconstruct a target signal from a very small number of samples. In this study, we applied CS to dispersion-tuned swept laser -OCT (DTSL-OCT) to reduce the number of sampling points required for image reconstruction. Although previous studies have shown that CS can be applied to DTSL-OCT for image reconstruction, the results were only qualitatively evaluated. Therefore, in this study, we conducted simulations and experiments, and evaluated quantitatively using the Mean Squared Error (MSE) between theoretical values and measured values.
