Strong lensing is one of the most spectacular views in the universe. Many
cosmological applications have been proposed, but the number of such lensing
systems is still limited. In this work, we applied an improved version of a
previously developed spectroscopic lensing search method to the SDSS-III BOSS
and proposed a list of highly possible candidates. Follow-up CFHT Megacam
imaging observations were performed for five systems, and two out of five are
probably strong lensing systems with at least one image close to the central
galaxy, although no counter images are detected.
