“…The signi®cance for the pixel-accurate image overlay of¯uorescence in Figure 6 is pixel-accurate delivery of therapeutics, such as photodynamic therapy. The bench-top size of the prototype scope is not a limitation in the future, and ultrathin designs are feasible [3]. Currently, 4-mm diameter lens systems have been assembled, as well as 2.4 mm tube piezo that can actuate ®ber scans at 30 degrees from a¯exible shaft, see Figure 8.…”

“…In contrast to pixel-array imaging, the resolution from scanning ®ber imaging is not dependent on the size and number of photodetectors [3]. To increase image resolution, the simple biconvex lens was replaced with a custom, 3-microlens combination of higher numerical aperture (5.0 mm ®eld of view at 6.8 mm from the distal lens with 2.6 mm depth of ®eld).…”

“…In that case the diameter of the fiber D sets the maximal spatial frequency transmitted by the fiber and therefore also the spatial resolution obtainable in the image plane: ( 4 ) and the fact that there are multiple cores is equivalent to sampling in the Fourier plane which means replication in the image plane yielding limiting restriction over the obtainable field of view:…”

“…The flexible endoscopes are being constructed out of a bundle of single mode fibers while each fiber in the bundle transmits backwards spatial information corresponding to a single spatial point, i.e. a single pixel [1][2][3][4][5]. The fibers bundle goes into the body while the imaging camera is located outside.…”

In this paper we present a design proposal as well as a preliminary experimental validation of special multi functional bio-medical probe. The resulted tip is very thin with external diameter of approximately 100μm-200μm that provides localization at which its functionalities can be applied. The high imaging resolution capability of 5,000-10,000 imaged pixels and the fact that the edge of the microprobe is very thin allows localized biomedical inspection, visualization and treatment with minimal invasive damage.

“…There are two main types of endoscopes: flexible and rigid. The flexible endoscopes are being constructed out of a bundle of single mode fibers while each fiber in the bundle transmits backward spatial information corresponding to a single spatial point, i.e., a single pixel [1][2][3][4][5]. The fibers bundle goes into the body while the imaging camera is located outside.…”
