Laser odometry taking account of the tilt on the laser sensor
2015 10th Asian Control Conference (ASCC), 2015Localization under water is required for an underwater mobile robot to perform the survey autonomously. There is a conventional method using inertial navigation system as a localization under water, but it takes high costs. In this study, we propose a laser odometry technique as a localization for underwater mobile robots.

Optically scanned laser line sensor
2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2020This work presents the system design, motion control and the evaluation of an optical scanning system, which manipulates only the illumination path of a laser line sensor by a galvanometer scanner. The selected system design minimizes aberrations due to the optical scanning through the scanner placement.

Testing of Airborne Laser Altimetry Sensors
2018 5th IEEE International Workshop on Metrology for AeroSpace (MetroAeroSpace), 2018This paper synthesizes the results of the mechanical shock, vibration and temperature tests that have been executed in order to verify the performance characteristics of the device under test (D UT) in environmental conditions representative of those which may be encountered during the operation of the equipment.

Applications of Laser Processing for Sensors and Actuators
MRS Proceedings, 1995ABSTRACTThe fabrication of sensors and actuators requires new materials with multicomponent stoichiometry as well as new three-dimensional microstructures. We present several potential applications of laser processing for the fabrication of sensors and actuators.

FIBER LASER HYDROPHONES AS PRESSURE SENSORS
International Journal of Modern Physics A, 2006The development of hydro-phonic sensors for deep see acoustic detection is described. The sensitive element is an erbium-doped single mode fiber laser, with the cavity delimited by two Bragg grating reflectors. The variations of temperature and pressure perturb the cavity, inducing a wavelength shift.

Tunable nanoblock lasers and stretching sensors
Nanoscale, 2016Reconfigurable, reliable, and robust nanolasers with wavelengths tunable in the telecommunication bands are currently being sought after for use as flexible light sources in photonic integrated circuits. Here, we propose and demonstrate tunable nanolasers based on 1D nanoblocks embedded within stretchable polydimethylsiloxane.

CIRP Annals, 1994
The goal of laser machining is to maximize the material removal rate, subject to quality constraints. Current industrial practice relies on trial-and-error to find acceptable process parameters. This is time-consuming, does not necessarily result in optimal operating conditions, and does not allow the adaptation of the process parameters to the actual ...

A low-cost laser distance sensor
2008 IEEE International Conference on Robotics and Automation, 2008Many indoor robotics systems use laser rangeflnders as their primary sensor for mapping, localization, and obstacle avoidance. The cost and power of such systems is a major roadblock to the deployment of low-cost, efficient consumer robot platforms for home use.
