Using Light Polarization in Laser Scanning
We use polarization analysis in triangulation-based laser scanners to disambiguate the true laser stripe from spurious inter-reflections caused by holes and concavities on metal surfaces. Stripe candidates are discriminated by projecting linearly polarised laser light and measuring the polarization state of the linearly polarized component of the observed stripe candidates. Initial experimental...
متن کاملDirectional light scanning laser ophthalmoscope.
The cone photoreceptor mosaic of the living human eye has in a limited number of cases been imaged without the use of wavefront-correction techniques. To accomplish this, the directionality of the photoreceptors, as manifested by their waveguiding properties, may be used to advantage. In the present paper we provide a model of our recently proposed directional light scanning laser ophthalmoscop...
متن کاملA Literature Review on Low Cost 3D Scanning Using Structure Light and Laser Light Scanning Technology
The 3D scanning system is increasingly used in various fields. The 3D scanner having the capability of capturing the real 3D objects in digitised form in the computer world. The generation of 3D model is required in various applications like in manufacturing industry to reverse engineering the existing components, to inspect the quality of manufacturing component, animation industry to model th...
متن کاملGlaucoma detection using scanning laser polarimetry with variable corneal polarization compensation.
OBJECTIVE To compare the ability of scanning laser polarimetry (SLP) to discriminate between healthy and glaucomatous eyes with manufacturer-assumed fixed and subject-specific variable corneal polarization magnitude (CPM) and corneal polarization axis (CPA) values. METHODS An SLP was modified to enable the measurement of CPM and CPA values so that compensation for corneal birefringence could ...
متن کاملLow-cost 3d Laser Scanning in Air or Water Using Self-calibrating Structured Light
In-situ calibration of structured light scanners in underwater environments is time-consuming and complicated. This paper presents a self-calibrating line laser scanning system, which enables the creation of dense 3D models with a single fixed camera and a freely moving hand-held cross line laser projector. The proposed approach exploits geometric constraints, such as coplanarities, to recover ...
