θmin=1.22λ/D
The Attempt at a Solution
(a)θmin=1.22λ/D
(b)θs=1.22(600nm)/30mm=24.4μm but what is spatial resolution and how to calculate it??
That answer should be in units appropriate for an angle, certainly not μm .kenok1216 said:Homework Statement

It's related to the angular resolution. You can think of the spatial resolution as the arc length of a circle subtended by the angle of angular resolution.kenok1216 said:what is spatial resolution and how to calculate it??

s=rθ, so what is r is this question?object distance? focal length?image distance?blue_leaf77 said:It's related to the angular resolution. You can think of the spatial resolution as the arc length of a circle subtended by the angle of angular resolution.
About the circle I was talking about, you can assume it to be centered at the center of the lens and since your image is located at the focal plane, the arc length of interest must touch the focal plane. What will r be?kenok1216 said:s=rθ, so what is r is this question?object distance? focal length?image distance?

Spatial resolution refers to the level of detail or clarity in an image or dataset. It is the smallest discernible feature or distance that can be represented in a given space.
Spatial resolution can be measured in a variety of ways, depending on the type of data being analyzed. For satellite imagery, it is often measured in meters per pixel. In microscopy, it may be measured in micrometers. Other methods of measurement include line pairs per millimeter or pixels per inch.
Spatial resolution is important because it impacts the quality and accuracy of data analysis. Higher spatial resolution allows for more precise and detailed measurements and can reveal smaller or more subtle features. It also enables scientists to better understand and interpret spatial patterns and relationships.
Spatial resolution can be improved through technological advancements, such as using higher resolution sensors or instruments. In some cases, spatial resolution can also be enhanced through image processing techniques, such as interpolation or super-resolution algorithms.
There are several limitations to spatial resolution, including the physical limitations of the technology used to collect data, atmospheric interference, and data processing techniques. Additionally, high spatial resolution can also result in larger file sizes and longer processing times.
