An apparatus for intraoral imaging has an illumination source that directs light to an object. An imaging apparatus forms an image at an image sensor array from reflected light from the object, the imaging apparatus having an optical stop along an optical axis. A phase modulator is disposed at or near the optical stop. An image processor conditions data from the image sensor array and provides processed image data of the object.

An endoscope stereo imaging device includes an endoscope lens assembly and an imaging module. The imaging module includes first, second and third lens assemblies, a beam splitter, first and second image sensors and a micro lens array. A light beam from the endoscope lens assembly is transmitted to the beam splitter after passing through the first lens assembly and is split into first and second portions of the light beam. The first portion light beam is transmitted to the first image sensor via the second lens assembly and forms a two-dimensional image. The second portion light beam is transmitted to the second image sensor via the third lens assembly and the micro lens array sequentially and forms a first three-dimensional image.

A medical imaging device includes an elongated shaft having proximal and distal ends, a handle detachably connected to the shaft, and a connector assembly. The connector assembly comprises a plug at the proximal end of the shaft with an outer circumferential wall and a first plurality of electrical terminals, and a receptacle in the handle with a cavity for the plug. An image sensor is at the distal end of the shaft, and a plurality of electrical conductors electrically connected to the image sensor, are electrically connected to the first plurality of electrical terminals. An inner circumferential wall of the receptacle includes a second plurality of electrical terminals, and the outer circumferential wall of the plug has a plurality of apertures therein through which the first plurality of electrical terminals establishes an electrical connection with the second plurality of electrical terminals when the plug is inserted in the receptacle.

A lens system (1) for a video endoscope comprises, in order from an object side, a cover glass (20), a first lens (40), a second lens (60) and one or more further lenses, wherein all lenses are single lenses. An aperture stop (21) is arranged at the object side of the first or the second lens (40, 60), all lenses on an image side of the aperture stop (21) are aspherical, all lenses are made of glass or of a crystalline material, and at least one lens has a refractive index n approximately equal to or exceeding 1.66. The invention also relates to an endoscope objective, to a video endoscope, and to a method for assembling an endoscope objective.

A circuit board design uses CMOS sensors for the tip section of a multi-viewing element endoscope. Side sensors and their optical assemblies are assembled to a common base board to save space. Individual base boards are separately constructed, inserted into grooves of a main base board, and are further connected to the main base board by means of flexible circuit boards.

Medical imaging camera head devices and methods are provided using light captured by an endoscope system or other medical scope or borescope. Afocal light from the scope is manipulated and split. The resulting first and second beams are passed through focusing optics to a single sensor. To take better advantage of the available number image sensor pixels, the beam may pass through lens elements (or prisms) to generate an anamorphic aspect ratio prior to being split, increasing the resolution of the image in one dimension. The afocal anamorphic beam is then split, and both images are focused on the image sensor. The anamorphism is compensated for in image processing, permitting higher resolution in one dimension along the image sensor. The manipulation of the beams prior to being split (and in some cases after or while being split) can take several forms, each offering distinct advantages over existing systems.

The disclosed subject matter includes devices and systems for extending the imaging capability of swept, confocally aligned planar excitation (SCAPE) microscopes to in vivo applications. In embodiments, the SCAPE microscope can be implemented as an endoscopic or laparoscopic inspection instrument.

The Bala Laparoscope System is a reusable and/or disposable embodiment of a modular, surgical laparoscope with removable interchangeable viewing angles that enable one laparoscope to be used in place of two separate conventional laparoscopes with different viewing angles. The invention provides for distal lens cleaning without removing the laparoscope from the body. In addition, the invention provides for integrated image-guided working channels for surgical tools; cauterization and laser ablation and internal drug delivery. The simplicity of its optical design allows a much longer useful instrument life than conventional laparoscopes and essentially eliminates the need to rebuild them.

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. 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.
