Various configurations include fiber-based wave-front sensors. Many of the disclosed configurations increase the imaging resolution and enable integration of additional modes of operation while maintain the endoscope very thin, such as spectral imaging and three dimensional imaging.

A camera head includes a mounting unit detachably connected to an eyepiece unit of an endoscope, the camera head capturing an object image emitted from the eyepiece unit. The eyepiece unit includes an abutting surface that is orthogonal to a central axis along an insertion direction of the endoscope into a subject, and the abutting surface extending over an entire circumference in a circumferential direction around the central axis. The mounting unit is connected to the eyepiece unit and is configured to relatively rotate the endoscope and the camera head around the central axis. The mounting unit includes a facing surface that faces the abutting surface, and a pressing portion that abuts the eyepiece unit and presses the eyepiece unit toward the facing surface along the central axis. The facing surface includes a projecting portion that projects toward the abutting surface and abuts the abutting surface.

Dental periscopes having mounting clips configured to couple to mobile devices are disclosed. A patient can mount the dental periscope to a mobile device by coupling the mounting clip of the periscope to the mobile device. The patient can then use the mobile device-mounted dental periscope to capture image and/or video data of one or more dental structures. The captured image/video data can be sent to a remote system to obtain a remote dental diagnosis based on the captured data. The remote diagnosis may be an automated diagnosis generated by a trained machine learning classifier.

According to some aspects, a medical imaging system is provided. The medical imaging system includes an illumination device and a medical imaging device. The illumination device includes a first light source configured to emit first light having a wavelength range. The illumination device further includes a second light source configured to emit second light having at least one predetermined wavelength band. The at least one predetermined wavelength band is within the wavelength range. The illumination device further includes a dichroic mirror configured to attenuate a portion of the wavelength range corresponding to the at least one predetermined wavelength band and to multiplex the second light with the first light such that the portion of the wavelength range of the first light is attenuated. The light multiplexed by the dichroic mirror is emitted from the illumination device along an optical axis and irradiates an observation site. The medical imaging device includes at least one sensor configured to receive light from the observation site.

A protective cover apparatus for an otoscope to serve as a barrier between the otoscope and an ear canal of a user is provided. The otoscope includes a camera body coupled to a camera head having an attachment groove. The protective cover apparatus includes an adapter with a tubular member that attaches to the camera head of the otoscope, a sleeve coupled to the adapter and having a central tubular member and an outer flared surface protruding from the top end of the central tubular member, and a cap coupled to the top end of the tubular member of the adapter and having a central opening that permits unobstructed access to the camera head of the otoscope.

An intraoral imaging system comprising an intraoral adapter. The intraoral adapter may be operably coupled to a mobile device. The intraoral adapter may comprise an elongated housing comprising a viewing channel. The viewing channel may define a field of view of an intraoral region of a subject's mouth for intraoral scanning using a camera of a mobile device. The elongated housing may comprise a flange that is positioned outside of the field of view of the intraoral region of the subject's mouth. The intraoral imaging system may further comprise an image processing unit configured to (i) process a plurality of intraoral images and/or videos captured using the camera of the mobile device, and (ii) determine a dental condition of the subject based at least in part on the plurality of intraoral images and/or videos.

An illumination apparatus includes a light converter disposed on a distal end surface of a light guide, the light converter being configured to emit illumination light, which is generated by converting optical characteristics of primary light that is guided by the light guide, in a forward direction which is on the light converter side of the distal end surface, and in a backward direction which is on the light guide side of the distal end surface. The illumination apparatus further includes a light collector configured to collect backward illumination light into the light guide such that the backward illumination light is guided backward by the light guide, and a heat exhauster configured to convert the backward illumination light, which is guided by the light guide, to heat, and to exhaust the heat.
