The software tool supporting a implementation of a cheap laser plane range finder (LPRF) with rotary table and its calibration is presented. We were motivated by a dual-arm robotic manipulation with soft free-form objects, e.g. a piece of garment. We need a precise surface measurement also as a reference data for the precision estimation of other depth acquiring methods as stereo vision. A lase...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...

objectives: fluoride therapy is important for control and prevention of dental caries. laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. the objective of this study was to compare the effects of co 2 and diode lasers on enamel fluoride uptake in primary teeth. materials and methods: forty human primary molars were randomly assigned to fou...

The Spectro-Radiometric Calibration Assembly (SRCA) provides on-orbit spectral calibration of the MODerate resolution Imaging Spectroradiometer (MODIS) reflected solar bands and this paper describes how it is accomplished. The SRCA has two adjacent exit slits: 1) Main slit and 2) Calibration slit. The output from the main slit is measured by a reference silicon photo-diode (SiPD) and then passe...

The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...

Diabetes mellitus (DM) is a serious disease that affects not only the patient’s internal organs, circulation system and eyesight, but also their entire body. There are reportedly more than 120 million diabetic patients in the world at the moment and this figure is expected to double within the next ten years. India is the country with the highest rateof diabetes patient, with a current figure o...

introduction: to investigate the ultrastructural changes of dentin irradiated with 980-nm diode laser under different parameters and to observe the morphological alterations of odontoblasts and pulp tissue to determine the safety parameters of 980-nm diode laser in the treatment of dentin hypersensitivity (dh). methods: twenty extracted human third molars were selected to prepare dentin discs. ...

PURPOSE To evaluate the dosimetric characteristics of a two-dimensional (2D) diode array detector irradiated with passively scattered proton beams. MATERIALS AND METHODS A diode array detector, MapCHECK (Model 1175, Sun Nuclear, Melbourne, FL, USA) was characterized in passive-scattered proton beams. The relative sensitivity of the diodes and absolute dose calibration were determined using a ...
