    1. Real-time Lissajous imaging with a low-voltage 2-axis MEMS scanner based on electrothermal actuation

      Real-time Lissajous imaging with a low-voltage 2-axis MEMS scanner based on electrothermal actuation
      Laser scanning based on Micro-Electro-Mechanical Systems (MEMS) scanners has become very attractive for biomedical endoscopic imaging, such as confocal microscopy or Optical Coherence Tomography (OCT). These scanners are required to be fast to achieve real-time image reconstruction while working at low actuation voltage to comply with medical standards. In this context, we report a 2-axis Micro-Electro-Mechanical Systems (MEMS) electrothermal micro-scannercapable of imaging large fields of view at high frame rates ...

    3. Swept-source optical coherence tomography microsystem with an integrated Mirau interferometer and electrothermal micro-scanner

      Swept-source optical coherence tomography microsystem with an integrated Mirau interferometer and electrothermal micro-scanner
      In the rapid evolution of gastrointestinal endomicroscopy, optical coherence tomography (OCT) has found many diverse applications. Until recently, the micro-optoelectro-mechanical systems (MOEMS) technology has been playing a key role in shaping the miniaturization of these components. We report here, to the best of our knowledge, a novel endoscopic microsystem. It is based on a spectrally tuned MOEMS Mirau micro-interferometer integrated with micro-electro-mechanical systems (MEMS) electro-thermal micro-scanner, operating in the regime ...

    4. Miniature multimodal endoscopic probe based on double-clad fiber

      Miniature multimodal endoscopic probe based on double-clad fiber
      Optical coherence tomography (OCT) can obtain light scattering properties with a high resolution, while photoacoustic imaging (PAI) is ideal for mapping optical absorbers in biological tissues, and ultrasound (US) could penetrate deeply into tissues and provide elastically structural information. It is attractive and challenging to integrate these three imaging modalities into a miniature probe, through which, both optical absorption and scattering information of tissues as well as deep-tissue structure can ...

    5. Miniature Endoscope for Multimodal Imaging

      Miniature Endoscope for Multimodal Imaging
      A single miniature endoscope capable of concurrently probing multiple contrast mechanisms of tissue in high resolution is highly attractive, as it makes it possible for providing complementary, more complete tissue information on internal organs hard to access. Here we describe such a miniature endoscope only 1 mm in diameter that integrates photoacoustic imaging (PAI), optical coherence tomography (OCT), and ultrasound (US). The integration of PAI/OCT/US allows for high-resolution ...

    6. Miniature probe integrating optical-resolution photoacoustic microscopy, optical coherence tomography, and ultrasound imaging: proof-of-concept

      Miniature probe integrating optical-resolution photoacoustic microscopy, optical coherence tomography, and ultrasound imaging: proof-of-concept
      In this Letter, we present a novel tri-modal miniature side-view probe, through which optical-resolution photoacoustic microscopy (OR-PAM), optical coherence tomography (OCT), and pulse-echo ultrasound (US) images can be coaxially acquired and displayed simultaneously. The probe consists of a common optical path for OR-PAM (light delivery) and OCT (light delivery/detection), and a 40-MHz unfocused ultrasound transducer for OR-PAM (photoacoustic detection) and US (ultrasound transmission/receiving) with an overall diameter of ...

    11. MEMS-Based Endoscopic Optical Coherence Tomography

      MEMS-Based Endoscopic Optical Coherence Tomography
      Early cancer detection has been playing an important role in reducing cancer mortality. Optical coherence tomography (OCT), due to its micron-scale resolution, has the ability to detect cancerous tissues at their early stages. For internal organs, endoscopic probes are needed as the penetration depth of OCT is about 1–3 mm. MEMS technology has the advantages of fast speed, small size, and low cost, and it has been widely used ...
