An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device has a reduced form factor as compared to prior devices, and it provides for more efficient transmission and capture of images.

The disclosed embodiments relate to a system that implements a side-viewing imaging catheter. This system includes a catheter sheath enclosing an imaging core, wherein the imaging core resents an internal optical channel coupled to an optical element located at the distal end of the imaging core. The optical element includes an internal reflective surface that reflects and focuses light transmitted via the optical channel in a direction orthogonal to a rotational axis of the catheter toward a target location, and returns reflected light from the target location back through the optical channel. This internal reflective surface of the optical element is shaped to focus the light so that a resulting beam shape at the target location has a small cross section area and substantially equal axial and transaxial dimensions.

A system comprises an image capture device, an augmented reality (AR) display to display, and a processing device. The processing deice receives image data of a dental arch from the image capture device and processes the image data using a plurality of detection rules, where each detection rule detects one or more dental conditions. The processing device determines a dental condition for the dental arch based on the processing, determines a position of an area of interest on the dental arch, wherein the area of interest is associated with the dental condition, generates a visual overlay comprising an indication of the dental condition at the position of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.

A scanning system is described herein which incorporates projecting a plurality of patterns onto an object of interest and capturing the reflected image. Each pattern is based at least in part on traversing a hypercube graph or a Fibonacci cube graph using a Hamiltonian path. The patterns are used to help define the three-dimensional shape of the underlying object of interest, while also providing more robust error-correcting properties. After the reflected image of the projected pattern is captured, the scanning system further processes and displays a three-dimensional model of the captured object of interest.

Provided is an optical fiber scanner capable of generating an image with excellent image quality, which displaces an emission end of an optical fiber by means of an optical scanning actuator and scans light emitted from the optical fiber, in which the optical fiber 31 includes a photonic crystal fiber at least in a propagation path of the light leading to the optical scanning actuator.

The at least two of the first sliding contact (71), the second sliding contact (72), the third sliding contact (73) and the fourth sliding contact (74) are coaxial.

An optical probe imaging system includes an optical probe having a multicore optical fiber. Distal optics image light propagating in the multicore optical fiber so as to generate a light pattern on a sample that is based on a relative position of the cores. A distal motor causes the light pattern to traverse a path across the sample. An optical receiver includes a first receiver receiving light that has traversed the path across the sample from one of the at least two cores and a second receiver receiving light that has traversed the path across the sample from the other of the cores, such that the first receiver and the second receiver detect light in parallel. A processor maps relative position of the cores at the distal facet based on signals generated by the receiver.

A scanner includes a lens assembly comprising a lens having a lens axis and a positioning system to adjust a focal plane of the lens assembly. The positioning system includes an outer element, an inner element coupled to the lens assembly, and a linear-motion bearing that couples the inner element to the outer element.
