Making an infrared distance sensor for a science fair project

[sidz_bitz]

i am a student in my high skool and i was planning of making a apparatus for my science fair which involves infrared technology for the physically disabled. I wanted to know whether it is possible me to make a infrared device to calculate distance of a body from the origin of infrared waves. i need guidence in how i will be able to make such a device. i would be even delighted if u could provide me with latest information on infrared technology.
