3D Printed Head for a Handheld Laser Scanning Confocal Microscope

The laser scanning confocal microscope head can axially move and perform z-slicing. The presented confocal microscope head is composed of (1) an optical fiber bundle, (2) a custom-designed mechanical housing and lastly, (3) an embedded electronic system to control the head and gather images from the samples. The dimensions of the housing are 88 x 160 x 110 mm; and it is 3D printed with 30% filling ratio using standard PLA 3D printing material. The presented handheld confocal microscope is capable of moving with 1 mu m step size back and forth in axial direction and has a dynamic range of 2 cm. The results show that cost-effective 3D printing methods are suitable for realizing a handheld confocal microscope with an axial movement feature. Using cheap and replaceable 3D printed parts can ease the cleaning and disinfection procedures in clinical practices

A 3D Polymer Based Printed Two-Dimensional Laser Scanner

27th Micromechanics and Microsystems Europe (MME) Workshop -- AUG 28-30, 2016 -- Cork, IRELANDA two-dimensional (2D) polymer based scanning mirror with magnetic actuation is developed for imaging applications. Proposed device consists of a circular suspension holding a rectangular mirror and can generate a 2D scan pattern. Three dimensional (3D) printing technology which is used for implementation of the device, offers added flexibility in controlling the cross-sectional profile as well as the stress distribution compared to the traditional planar process technologies. The mirror device is developed to meet a portable, miniaturized confocal microscope application in mind, delivering 4.5 and 4.8 degrees of optical scan angles at 111 and 267 Hz, respectively. As a result of this mechanical performance, the resulting microscope incorporating the mirror is estimated to accomplish a field of view (FOV) of 350 mu m x 350 mu m

Development of Automated Laser Scanning System for Structural Health Monitoring of Wind Turbines

25th Signal Processing and Communications Applications Conference (SIU) -- MAY 15-18, 2017 -- Antalya, TURKEYIn recent years, the growing interest and demand in wind energy requires developing new wind turbines with larger size and capacity. However, this situation also causes some new and challenging problems which have not been encountered before in design, operation and maintenance. Strong winds and severe environmental factors can cause cracks and damage on several turbine components such as blades and tower. Determination of the location and extent of this damage at early stages is essential to ensure safe and efficient operation of the turbine. This work aims at developing a new motorized laser Doppler scanning system which can rotate about two axes freely. This new device will enable structural dynamics of the turbine to be monitored remotely by using optical measurement techniques. The developed laser system will be used to take vibration measurements on the structure regularly. The acquired measurements will be compared with the reference measurements taken on the undamaged structure and be used to detect possible damage on the turbine while turbine is parked.Turk Telekom,Arcelik A S,Aselsan,ARGENIT,HAVELSAN,NETAS,Adresgezgini,IEEE Turkey Sect,AVCR Informat Technologies,Cisco,i2i Syst,Integrated Syst & Syst Design,ENOVAS,FiGES Engn,MS Spektral,Istanbul Teknik Uni
