Here, the mixed ray transform is restricted over lines passing through a fixed curve ? in R3 satisfying certain geometric conditions. The main theorem of the article shows that a second-order tensor field can be recovered from its restricted mixed-ray transform up to the kernel of the transform, a smoothing term, and a known singular term.en-USe-Printe-Print123456789/555
