Nowadays laser is extensively used in various industrial, communicative, medical, and other fields. Using laser in medicine has enabled physicians to perform the most accurate and finest operations within few minutes. Non-observance of safety points during laser performance could be seriously harmful for the medical staff and the patient. Therefore, in order to prevent the possible damage of th...

Laser scanning is a non-invasive method for collecting and parameterizing 3D data of well reflecting objects. These systems have been used for 3D imaging of plant growth and structure analysis. A prerequisite is that the recorded signals originate from the true plant surface. In this paper we studied the effects of species, leaf chlorophyll content and sensor settings on the suitability and acc...

Two ways of tree structure reconstruction from laser-measurements are comparatively presented with respect to their suitability for functional interpretation of tree structures. A concept for physiological evaluation of the data is tested that comprises three steps: 1. The automated evaluation of terrestrial laser-scanner data, 2. application of a fine-scaled 3D-light model, and 3. a nitrogen d...

The paper presents results from several pilot studies on the application of terrestrial laser scanning in forest inventory tasks with the goal of automatically determining inventory-relevant tree parameters. The basic data sets have been provided using two different terrestrial laser scanners, one based on the time of flight distance measuring technique and the other one based on phase measurem...

PURPOSE To describe the process used by Optical Express, a large corporate refractive surgery provider, to develop evidence-based patient selection guidelines for laser vision correction. METHODS The evaluation of patient selection criteria for laser vision correction is part of a larger corporate process of continuous quality improvement and clinical due diligence. The procedures used to eva...

High-power vortex light generated directly from lasers will help drive their applications in material processing, optical manipulation, levitation, particle acceleration, and communications, but limited power has been achieved to date. In this work, we demonstrate record average of 31.3 W a laser, the best our knowledge, using an interferometric mode transforming output coupler convert fundamen...

AIMS To determine whether acute dacryocystitis complicated by abscess formation can be successfully treated using laser assisted endonasal dacryocystorhinostomy. METHODS A protocol was adopted for the management of acute dacryocystitis presenting to an ophthalmology department. All patients were assessed jointly by an ophthalmologist and otolaryngologist for their suitability for primary inte...

BACKGROUND The gold standard for the diagnosis of schistosomiasis is the detection of the parasite's characteristic eggs in urine, stool, or rectal and bladder biopsy specimens. Direct detection of eggs is difficult and not always possible in patients with low egg-shedding rates. Confocal laser scanning microscopy (CLSM) permits non-invasive cell imaging in vivo and is an established way of obt...
