A Linear Displacement Tilt Self-corrected Tansducer Based on a Discrete Position Detector
نویسندگان
چکیده
The article presents an optical displacement transducer with tilt self-correction capabilities. As the transducer components it can be mentioned a pixel linear array (PLA) circuit, a reflective surface and two laser diodes. A data acquisition board performs the control and acquisition tasks, which control the laser diode drivers (LDD) and PLA. Acquiring the digital output signal from the PLA the reflective surface displacement is evaluated. Several processing blocks developed in LabVIEW extract the measurement information avoiding the reflective surface tilt effects. Simulation and experimental results are presented.

Background and Aims: Accurate bone measurements are essential for determining the optimal size and length of proposed implants. The radiologist should be aware of the head position effects on image dimensions in each imaging technique. The purpose of this study was to evaluate the effect of mandibular plane angle on image dimensions in linear tomography.Materials and Methods: In this in vitro s...
متن کاملHead and trunk movement responses in healthy children to induced versus self-induced lateral tilt.
The purpose of our study was to determine head and trunk movement responses that occur in healthy 7-year-old children during induced and self-induced lateral tilt. Twenty subjects, while tailor sitting on a tiltboard, participated in three trials of both induced and self-induced left and right lateral displacements. Measurements of neck and trunk lateral flexion; trunk counterrotation; and neck...

متن کاملDetection of Outliers and Influential Observations in Linear Ridge Measurement Error Models with Stochastic Linear Restrictions
The aim of this paper is to propose some diagnostic methods in linear ridge measurement error models with stochastic linear restrictions using the corrected likelihood. Based on the bias-corrected estimation of model parameters, diagnostic measures are developed to identify outlying and influential observations. In addition, we derive the corrected score test statistic for outliers detection ba...
متن کاملComparison of different reconstruction methods for planar images in small gamma cameras
In this work we present a comparison of different methods for reconstructing the position of the events detected by gamma cameras with small Field of View. This task was completed within a project aimed to the development of an ultra high resolution, MR compatible PET detector camera head based on SiPM detector. It is well known that the spatial resolution deteriorates and the displacement erro...
