What can a digital imaging system do?

(Click on the robot)

Other uses:

Spectroscopy of vegetables to detect disease (Dr. Thai's research)

Digital libraries - viewing documents over the web

Virtual museums - viewing real art over the web

Virtual human body - Realplayer "melt-through" of the human body

Satellite images of the world - That's actually John Martin's house!

Operating robots in hazardous locations

There are thousands more uses...create your own!

Course objective: The student will be able to demonstrate the ability to select and combine different components of a digital imaging system, given a set of user-defined requirements.

In this course, you will be able to create your own digital imaging system that suits your purposes.

Lesson Objective: Given the size of a scene to be imaged, and a CCD imaging sensor of a particular size, The student will be able to demonstrate the calculation of the focal length of a lens that would render a complete image of the scene onto the imaging sensor.

In this lesson, you will select a lens for a given digital imaging system by calculating the focal length needed for the system.
