Short Description of Topic

The Main Idea

Angular Resolution is the ability of a device to visibly separate two different objects in space that are located a close angular distance to each other. The closer the objects are while the device can still see distinguish between them, the higher the angular resolution is.

Angular resolution is also referred to as spatial resolution.


A Mathematical Model

The equation for angular resolution is [math]\displaystyle{ {∆θ = \frac{λ}{W}} }[/math] where W is the width of the device

A Computational Model

The top most image demonstrates the highest angular resolution. It is most able to differentiate between the two objects. The bottom image demonstrates the lowest angular resolution. It is unable to differentiate between the two objects.
