“…Either the core or the inner cladding can be used to deliver the fluorescence excitation light, although it was shown that a core delivery allows better fluorescence imaging resolutions [ 77 ]. Additional modalities can be added to such a system including red-blue-green (RGB) reflectance [ 63 ] or spectrally-encoded confocal microscopy (SECM) [ 78 ]. Fluorescence detection can be acquired over a large spectrum for spectroscopic analysis [ 12 ] or target a specific compound by detecting its associated wavelength band.…”

Optical fibers have been used to probe various tissue properties such as temperature, pH, absorption, and scattering. Combining different sensing and imaging modalities within a single fiber allows for increased sensitivity without compromising the compactness of an optical fiber probe. A double-clad fiber (DCF) can sustain concurrent propagation modes (single-mode, through its core, and multimode, through an inner cladding), making DCFs ideally suited for multimodal approaches. This study provides a technological review of how DCFs are used to combine multiple sensing functionalities and imaging modalities. Specifically, we discuss the working principles of DCF-based sensors and relevant instrumentation as well as fiber probe designs and functionalization schemes. Secondly, we review different applications using a DCF-based probe to perform multifunctional sensing and multimodal bioimaging.

“…This device worked analogously to other OCT devices, except for the difference that the red/green/blue (RGB) light was emitted from the central core, while the collection of the reflected light was performed through the inner cladding. The separation of the various light signals from three modalities was done using an additional WDM [ 50 ].…”

Endoscopes are used routinely in modern medicine for in-vivo imaging of luminal organs. Technical advances in the micro-electro-mechanical system (MEMS) and optical fields have enabled the further miniaturization of endoscopes, resulting in the ability to image previously inaccessible small-caliber luminal organs, enabling the early detection of lesions and other abnormalities in these tissues. The development of scanning fiber endoscopes supports the fabrication of small cantilever-based imaging devices without compromising the image resolution. The size of an endoscope is highly dependent on the actuation and scanning method used to illuminate the target image area. Different actuation methods used in the design of small-sized cantilever-based endoscopes are reviewed in this paper along with their working principles, advantages and disadvantages, generated scanning patterns, and applications.

“…The new fibre optic and rigid endoscopic techniques have greatly enhanced the diagnostic and dynamic assessment of tumours of the upper aerodigestive tract, particularly the pharynx and larynx [1,2]. The fibre optic endoscope can be further used for optical coherence tomography (OCT) [3,4] and the fiber-optic Raman probe [5] to enhance in-vivo diagnosis of early cancer during endoscopy. A new approach in endoscopic technology today is the electronic endoscope -a medical instrument that can send a front-end device into the human body through a natural entrance of human body or a deliberate surgical incision to observe the tissues and organs in the body [6].…”

The optical fibre endoscope with cold light is still mainstream in the endoscope market, but the inherent structural characteristics of the optical fibre endoscope lead to its shortcomings, such as high price, inconvenient to carry, and easy distortion of image. The micro medical electronic endoscope can receive the front-end optical system image through the miniature CCD (Charge Coupled Device) and transmit the image to the display through the cable, which greatly solves the limitations of the optical fibre endoscope. In this paper, using ZEMAX software, an optical imaging system with 75 • field of view is designed. The system consists of four lenses, and all of them are standard spherical lenses. The maximum aperture is 2.2 mm and can match the 1/10-inch CCD. The distortion of the edge field of view is less than 20%, the aberration is small, and the light convergence is good. The maximum spatial resolution is 175 lp/mm.
