    3D Printed Head for a Handheld Laser Scanning Confocal Microscope
    (Maik Nauka/Interperiodica/Springer, 2021) Yildirim, I. D.; Sarioglu, B.; Gokdel, Y. D.
    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
    (Iop Publishing Ltd, 2016) Oyman, H. A.; Gokdel, Y. D.; Ferhanoglu, O.; Yalcinkaya, A. D.
    A 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.

    RoboSantral An autonomous mobile guide robot
    (IEEE, 2015) Denker, A.; Dilek, A. U.; Sarioglu, B.; Savas, J.; Gokdel, Y. D.
    RoboSantral, An autonomous mobile robot which has been designed and realized in order to guide the visitors through a university campus, is presented in this paper. This robot accompanies guests through the campus and gives presentations on predefined locations. Location data is obtained from GPS sensors. Targets such as faculty buildings, museums etc... are recognized by the image processing of pre-defined tags. As microprocessor and microcontroller, Raspberry Pi and Arduino are used respectively.
