Depth profiling

Definition

Depth profiling is a technique used to obtain information about the variations of material properties at different depths within a sample. This method allows for the analysis of the internal structure and composition of a sample, making it particularly useful in imaging technologies that require insight into subsurface layers. By employing specific techniques, depth profiling can reveal critical information regarding tissue structures, layer thicknesses, and other important characteristics that may not be visible on the surface.

5 Must Know Facts For Your Next Test

1. Depth profiling allows for the visualization of structures at varying depths, making it essential for understanding complex biological tissues.
2. In optical coherence tomography, depth profiling is achieved by measuring the time delay of reflected light from different layers within a sample.
3. This technique provides high-resolution images, which are crucial for applications in medical diagnostics, particularly in ophthalmology.
4. Depth profiling can also be enhanced by using specific imaging algorithms that improve the clarity and detail of subsurface structures.
5. The ability to perform non-invasive depth profiling makes it valuable for monitoring changes in tissue over time without requiring surgical intervention.

Review Questions
