In this manuscript, we report a fast speed swept source endoscopic OCT system utilizing a 4.5mm diameter rigid GRIN lens rod probe. The rigid probe has a tunable working distance with tuning range 0̃7mm. The system could take front scanning images with speed of 40frames per second (512 A line per frame). The probe can work in contact and non contact mode. Fast speed contact and non-contact imaging was demonstrated.
