Extra Large Aperture FPCB Mirror Based Scanning LiDAR
IEEE/ASME transactions on mechatronics, 2022This article presents an extra-large (25 × 50 mm2) flexible printed circuit board (FPCB) mirror to cover both the emitting and receiving lenses of a single-point LiDAR to form a biaxial scanning LiDAR with a compact structure and long measurement ...

Small scanning mirror mechanism
Proceedings 2003 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM 2003), 2004The CSEM has developed an optomechanical linear scanner. This scanner has a limited displacement range, performed with high resolution. The resolution is obtained through a very high precision motion guiding of the scanner itself. This paper describes the main features of the scanner system as well as its control system. After a complete description of

Laser beam scanning by rotary mirrors I Modeling mirror-scanning devices
Applied Optics, 1995Avector approach to tracing the path of a laser beam through an optical system containing movable plane mirrors is described, which permits a unified treatment of a number of basic mirror-scanning devices. We show that the scan field produced by the mirror-scanning system is a curved surface with a straight line as its generating element.

IEEE Transactions on Antennas and Propagation, 2021
A periodic mirror-reflected circular-polarized (CP) leaky wave antenna (LWA) with dual beam-scanning in dual polarization types is reported in this paper. The unit cell of the proposed antenna consists of two oblique stubs that are orthogonally separated

Photoacoustic endomicroscopy based on a MEMS scanning mirror.
Optics Letters, 2017In this Letter, we present a high-resolution photoacoustic endomicroscopy probe based on a microelectromechanical systems (MEMS) scanning mirror. The built-in optical assembly consists of a 0.7 mm graded-index (GRIN) lens for light focusing and a ϕ1 mm ...

SPIE Proceedings, 2004
A 1500-μm-diameter silicon/silicon nitride 3D scan mirror has been built using MEMS technology. It is capable of static and dynamic beam scanning achieved with a bi-axial gimbal. A gold-coated deformable membrane at the center of the device provides both focus control (z-axis) and spherical aberration correction.

Silicon Torsional Scanning Mirror
IBM Journal of Research and Development, 1980Conventional batch photolithography and thin film techniques are employed to fabricate an electrostatically driven torsional scanning mirror from single-crystal silicon. This device is extremely simple to make and operate, has operational characteristics comparable to commercial magnetically driven high-frequency scanners, and has exhibited a promising

Dynamic deformation of scanning mirrors
2000 IEEE/LEOS International Conference on Optical MEMS (Cat. No.00EX399), 2002Summary form only given. MEMS mirrors are capable of scanning at frequencies greater than 34 kHz. Both diffraction and dynamic deformation are dependent on the mirror size; increasing the mirror length decreases diffraction, but increases dynamic deformation.
