DETECTION OF WATER SURFACES IN FULL-WAVEFORM LASER SCANNING DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Airborne laser scanning has become a standard method for recording topographic data. A new generation of laser scanners digitises the complete waveform of the backscattered signal and thus offers the possibility of analysing the signal shape.

Scanning the macula for detecting glaucoma

open access: yesIndian Journal of Ophthalmology, 2014
With the advent of spectral domain optical coherence tomography (SDOCT), there has been a renewed interest in macular region for detection of glaucoma. However, most macular SDOCT parameters currently are thickness parameters which evaluate thinning of the macular layers but do not quantify the extent of area over which the thinning has occurred.

Direct and automatic measurements of stem curve and volume using a high-resolution airborne laser scanning system

open access: yesScience of Remote Sensing, 2022
Today, high-quality reference tree measurements, including the position, diameter, height and volume, are cumbersome and slow to carry out, but highly needed for forest inventories based on airborne laser scanning. Mobile laser scanning technologies hold
