Accurate distance sensor


Total newbie with regards to robotos, but fascinated by the topic. I'm working on a hobby project, which is not really a robot, but I need "robot" components. I'm searching for an accurate distance sensor, capable of sensing distance between 0 and 5 cm (could also between 1 and 6, for instance), with accuracy around 0,1mm. I see some of you are using Sharp distance sensor GP2Y0A02YK0F and similar, but I have not found what is the accuracy of those sensors, so I don't know if it would be appropriate.
