Key Points

The aim is to develop a method for accurate retrieval of tissue optical properties in hollow organs using self-calibration.
Utilized endoscopic iso-pathlength points for measurements
Employed a new framework for optical sensing in cylindrical tissues
Conducted absorption measurements in complex geometries
Demonstrated feasibility of self-calibrated absorption techniques
Improved depth-resolved sensing capabilities
Opened avenues for enhanced diagnostic tools in digestive and hollow organs

Abstract

The demonstration of IPL points in endoscopic geometry provides a new framework for depth-resolved optical sensing in hollow cylindrical tissues. This approach may enable self-calibrated absorption measurements and open the way for improved diagnostic tools in the digestive system, esophagus, and other hollow organs where conventional endoscopy lacks depth information.
