Publication number: 20210341670Abstract: Multicore fibers and endoscope configurations are provided, along with corresponding production and usage methods. Various configurations include an adiabatically tapered proximal fiber tip and/or proximal optical elements for improving the interface between the multicore fiber and the sensor, photonic crystal fiber configurations which reduce the attenuation along the fiber, image processing methods and jointed rigid links configurations for the endoscope which reduce attenuation while maintaining required flexibility and optical fidelity. Various configurations include spectral multiplexing approaches, which increase the information content of the radiation delivered through the fibers and endoscope, and configurations which improve image quality, enhance the field of view, provide longitudinal information. Various configurations include fiber-based wave-front sensors.Type: ApplicationFiled: July 11, 2021Publication date: November 4, 2021Applicant: Z Square Ltd.Inventors: Asaf SHAHMOON, Zeev ZALEVSKY

Publication number: 20200281451Abstract: A system for imaging may include an illumination system that includes a light source to generate a light beam; and a spatial encoding pattern generator comprising one or a plurality of optical elements to encode the imaging beam so as to concurrently illuminate an object by a plurality of different spatial encoding patterns, wherein each encoding pattern of said different encoding patterns is characterized by a distinct wavelength of the imaging pattern. The system may also include an imaging sensor for receiving the encoded imaging beam transmitted through the object or reflected off the object; and a processor for decoding image data from the imaging and reconstructing an image of the object.Type: ApplicationFiled: March 7, 2019Publication date: September 10, 2020Applicant: Z Square Ltd.Inventors: Zeev ZALEVSKY, Omer Itzchak WAGNER, Asaf SHAHMOON

Publication number: 20200015669Abstract: Endoscopes, multicore endoscope fibers and configuration and operation methods are provided. The fibers may have hundreds or thousands of cores and possibly incorporate working channel(s) and additional fibers. The fiber may be used at different optical configurations to capture images of tissue and objects at the distal tip and to enhance a wide range of optical characteristics of the images such as resolution, field of view, depth of field, wavelength ranges etc. Near-field imaging as well as far-field imaging may be implemented in the endoscopes and the respective optical features may be utilized to optimize imaging. Optical elements may be used at the distal fiber tip, or the distal fiber tip may be lens-less. Diagnostics and optical treatment feedback loops may be implemented and illumination may be adapted to yield full color images, depth estimation, enhanced field of views and/or depths of field, and additional diagnostic data.Type: ApplicationFiled: September 2, 2019Publication date: January 16, 2020Applicant: Z Square Ltd.Inventors: Asaf SHAHMOON, Zeev Zalevsky
