Yes, there is a module called 'who's viewed my profile'. However, if you just open a basic free account and don't do anything with the settings, you won't automatically receive this information. This is because your privacy settings are set to anonymous unless you change them. So if you want to know who has viewed your profile, you have to go to Privacy Settings and agree to be visible, or else upgrade to a premium account. You can change back at any time.

When you have changed your status, you will have a link on the right hand side of your page that tells you how many people have viewed your profile, and if you click on it you can see their names. People who have chosen to remain anonymous will appear as 'Someone from X industry' etc (which is how you will appear too unless you change to the visible setting).
For more information, the LinkedIn website has a good help/FAQ section.
