Abstract

The Ring Profiler was developed to examine the cross-sectional morphology of wood tracheids in a 12.5-mm core sample. The instrument integrates a specially designed staging apparatus with an optical imaging system to obtain high-contrast, high-resolution images containing about 200-500 tracheids. These images are further enhanced and analyzed to extract tracheid cross-sectional properties such as shape, double-wall thickness, and lumen area. Subsequently, localized density can be calculated for specific regions of interest (e.g., earlywood and latewood), as it varies throughout the tree.
