Folder "USAF_target_images" contents

The folder consists of:
• 2 image frames
"Target_in_air.png"
"Target_in_water.png"
• 1 Readme file
"USAF_target_images_README"

Abstract
This folder contains reference images of a USAF resolution test target acquired using the imaging platform under air and water conditions. These images are provided to evaluate optical alignment, focus, and spatial resolution of the camera system, as well as to assess the effect of the imaging medium on image quality. The dataset supports optical calibration and performance validation of the platform independently of electrochemical measurements.

Content of the files
• file "Target_in_air.png" contains a PNG image frame of the USAF resolution test target acquired under ambient air conditions.
• file "Target_in_water.png" contains a PNG image frame of the USAF resolution test target acquired with the target immersed in water.

File Specifics
The dataset includes image files in PNG captured and saved using custom-developed platform software.
