There are several synonyms which can be used instead of "take one look at." One may say "glance at," "peer at," or "inspect." Other options include "survey," "scrutinize," and "peruse." If one wants to emphasize the brief nature of the action, they may use "glimpse" or "peek." Alternatively, the phrase "cast an eye on" can be used to indicate a quick look without necessarily implying a passing glance. Each of these synonyms implies a different intensity or purpose behind the act of looking, conveying a slight variation in meaning.
