Depth of field is a measurement of the maximum object depth that can be maintained entirely in focus. Since depth of field is dependent on resolution resolution and contrast, determining this parameter affects what one is trying to analyze or measure. Gregory Hollows, Director of Machine Vision Solutions, discusses this often misunderstood fundamental parameter and provides an imaging tip that is applicable to any optical design. View Module 1.8: Depth of Field In Depth for more detailed information. You can also learn more in our Gauging Depth of Field in Your Imaging System application note.
