Microfabrication of Fiber Optic Scanners
SPIE Proceedings, 2002A cantilevered optical fiber is micromachined to function as a miniature resonant opto-mechanical scanner. By driving the base of the cantilevered fiber at a resonance frequency using a piezoelectric actuator, the free end of the cantilever beam becomes a scanned light source. The fiber scanners are designed to achieve wide field-of-view (FOV) and high

An Electro-Thermally Actuated Micro-Cantilever-Based Fiber Optic Scanner [PDF]
IEEE Sensors Journal, 2020 A sub-millimeter sized optical scanner driven by electro-thermal actuation is presented. The scanner is composed of a single-mode optical fiber (SMF) with a cantilevered section at its distal tip. The fiber cantilever is electro-thermally actuated near its base in a single direction and excited at resonance to obtain large deflections at the tip of the

Scanning Properties of a Resonant Fiber-Optic Piezoelectric Scanner
Review of Scientific Instruments, 2011We develop a resonant fiber-optic scanner using four piezoelectric elements arranged as a square tube, which is efficient to manufacture and drive. Using coupled-field model based on finite element method, scanning properties of the scanner, including vibration mode, resonant frequency, and scanning range, are numerically studied.

Compact Optical Path Scanner and Its Application for Decoding Fiber-Optic Interferometers
Optics Letters, 2010This Letter describes a compact optical path scanner for decoding fiber-optic interferometers. The active component of the scanner is a segment of liquid sealed in a fused silica hollow fiber. When the volume of the liquid is changed by an attached thermoelectric cooler, one end facet of the liquid moves along the hollow fiber, and the optical path of ...

An optical scanner based on electromagnetically actuated optical fiber
SPIE Proceedings, 2006To meet the performance requirements for some applications, including small sizes, precise optics, low power consumption and non-electrical control in the devices, an optical fiber scanner using electromagnetic actuation has been developed. This paper acquaints a compact external magnetic field actuated fiber optic scanner, in which the main structure ...

Fiber-Optic Frequency Shifter Using a Grating Acoustic Scanner
Optics Letters, 1987A fiber-optic single-sideband frequency shifter using a grating acoustic scanner has been demonstrated. By using the surface-wave-to-bulk-wave conversion mechanism of a LiNbO(3) scanner, a traveling acoustic bulk wave with a frequency of approximately 42 MHz was generated and was incident at an angle upon an optical fiber.

Fiber-Optic Confocal Microscope Using a MEMS Scanner and Miniature Objective Lens
Optics Express, 2007 We designed and constructed a single-fiber-optic confocal microscope (SFCM) with a microelectromechanical system (MEMS) scanner and a miniature objective lens. Axial and lateral resolution values for the system were experimentally measured to be 9.55 mum and 0.83 mum respectively, in good agreement with theoretical predictions.

A compact optical fiber scanner for medical imaging
SPIE Proceedings, 2006A compact fiber optic scanner for biomedical applications such as optical coherent tomography has been designed, fabricated and tested. The scanner is designed as an in vivo device and composed of an optical fiber coated with nickel-powder loaded paint for external magnetic actuation.
