    2. A miniature endoscopic optical coherence tomography probe based on C-lens

      A miniature endoscopic optical coherence tomography probe based on C-lens
      We present a novel miniature endoscopic OCT probe based on an electrothermal microelectromechanical (MEMS) mirror and a C-lens. The MEMS mirror has a relatively large mirror plate of 0.5 mm0.5 mm on a small chip size of 1.5 mm1.3 mm, leading to the outer diameter of the endoscopic probe down to only 2.5 mm so that the probe is capable of being inserted through the ...

    3. Common-path optical coherence tomography using a microelectromechanical-system-based endoscopic probe

      Common-path optical coherence tomography using a microelectromechanical-system-based endoscopic probe
      This paper presents a common-path (CP) swept-source optical coherence tomography (SSOCT) system based on a special endoscopic probe design with an in-line internal reflection as the reference and a two-axis electrothermal microelectromechanical system mirror for image scanning. The rear surface of a gradient reflective index (GRIN) lens inside the probe is set as the reference reflection plane. The length of the GRIN lens is optimized to eliminate the artifacts in ...

      Swept-source common-path optical coherence tomography with a MEMS endoscopic imaging probe
      A MEMS-based common-path endoscopic imaging probe for 3D swept-source optical coherence tomography (SSOCT) has been developed. The common path is achieved by setting the reference plane at the rear surface of the GRIN lens inside the probe. MEMS devices have the advantages of low cost, small size and fast speed, which are suitable for miniaturizing endoscopic probes. The aperture size of the two-axis MEMS mirror employed in this endoscopic probe ...

    7. Correction of image distortions in endoscopic optical coherence tomography based on two-axis scanning MEMS mirrors

      Correction of image distortions in endoscopic optical coherence tomography based on two-axis scanning MEMS mirrors
      A two-axis scanning microelectromechanical (MEMS) mirror enables an optical coherence tomography (OCT) system to perform three-dimensional endoscopic imaging due to its fast scan speed and small size. However, the radial scan from the MEMS mirror causes various distortions in OCT images, namely spherical, fan-shaped and keystone distortions. In this paper, a new method is proposed to correct all of three distortions presented in OCT systems based on two-axis MEMS scanning ...

    10. Design optimization and implementation of a miniature optical coherence tomography probe based on a MEMS mirror

      Design optimization and implementation of a miniature optical coherence tomography probe based on a MEMS mirror
      Optical coherence tomography (OCT) provides non-invasive cross-sectional imaging capability and high resolution, but it has very limited applications inside human body because of the stringent size requirements for accessing the internal organs. Micro-Electro-Mechanical Systems (MEMS) is an emerging technology that can make devices with small size and fast speed. This paper reports the design optimization of a MEMS mirror-based miniature OCT probe. The probe consists of three main parts: a ...
