A New, Adaptable, Optical High-Resolution 3-Axis Sensor
This article presents a new optical, multi-functional, high-resolution 3-axis sensor which serves to navigate and can, for example, replace standard joysticks in medical devices such as electric wheelchairs, surgical robots or medical diagnosis devices. A light source, e.g., a laser diode, is affixed to a movable axis and projects a random geometric shape on an image sensor (CMOS or CCD). The d...
متن کاملAn Acousto-Optical Sensor with High Angular Resolution
The paper introduces a new laser interferometry-based sensor for diagnosis of random media by means of high accuracy angle measurements and describes the results of its development and testing. Theoretical calculations of the dependence of the range of the laser interferometer on laser beam parameters, device geometry, and atmospheric turbulence characteristics are reported. It is demonstrated ...
متن کاملHigh Resolution Optical Spectroscopy
This experiment will allow you to learn a specific optical technique with applications over a wide variety of phenomena. You will use a commercial spectrometer (a very common piece of equipment in research labs) to obtain the emission wavelengths of particular elements (e.g. mercury, sodium, hydrogen and deuterium) as well as to compare the outputs of gas and solid state lasers. You will be abl...
متن کاملHigh spatial resolution distributed optical fibre dynamic strain sensor with enhanced frequency and strain resolution
A distributed optical fibre dynamic strain sensor with high spatial and frequency resolution is demonstrated. The sensor which uses φ-OTDR interrogation technique exhibited a higher sensitivity thanks to an improved optical arrangement and a new signal processing procedure. The proposed sensing system is capable of fully quantifying multiple dynamic perturbations along a 5km long sensing fibre ...
