The single measurement area in traditional spatial carrier digital speckle pattern interferometry (SC-DSPI) is limited by its small viewing angle owing to its optical path limitation. In this paper, a SC-DSPI optical path with a large field of view is proposed. A 4F optical system based on the traditional SC-DSPI optical path is added for image transmission, which enables a short-focus lens used in the optical path for imaging to expand the measurement viewing angle, thus realizing a large field of view measurement. The experiment results show that when the measurement distance is 310 mm, the proposed SC-DSPI optical path with a large field of view can realize the entire field deformation measurement of an object with a 180 mm diameter; the obtained phase diagram has high quality. The proposed SC-DSPI facilitates effective measurement.
