An imaging device (010, 10, 110) comprises a first optical system (020, 20, 120) at a distal end of the imaging device, a second optical system (080, 80, 180) towards the proximal end of the imaging device, and a sensor (074, 74, 174) at the proximal end of the imaging device. The first and second optical systems and the sensor are aligned along a common longitudinal axis. The first optical system is or comprises one or more reflective and/or refractive optical components (24, 124; 22, 122) symmetrically and/or coaxially arranged with respect to the longitudinal axis, and the second optical system comprises one or more reflective and/or refractive optical components (24, 124; 22, 122) for focussing incident light towards the sensor. A calibration system (200) and method for calibrating such an imaging device, and a method of processing image data obtained from such an imaging device are also provided.

A medical endoscopic instrument includes a distal elongated insertion section (1) for minimally invasive insertion into a human or animal body, with at least one LED (5) arranged in a distal end section of the insertion section (1), and a lens system (19) arranged distally of the LED (5) with an optical axis (x). The lens system (19) includes a first lens (29) and a second lens (31) arranged distally of the first lens (29). The second lens (31) has a proximally extending sleeve extension (35). The sleeve extension (35) has a first reference surface for positioning the second lens (31) in relation to the insertion section (1) and a second reference surface (39) for positioning the first lens (29) in relation to the second lens (31).

During an inspection method, an inspection scope is inserted into an interior of an apparatus of a gas turbine engine. An image of the interior of the apparatus is captured to provide/output image data. A location of the inspection scope within the interior of the apparatus when the image is captured is determined to provide location data, where the determining of the location includes comparing the image data to model data from a model of the apparatus. During the course of inspection, movement of the inspection scope is tracked within the interior of the apparatus using the location data. The location data may be derived by feature recognition and/or motion tracking of live feed from a scope video output to features available in a field of view within duplicate CAD model.

A borescope for use within an unlit, closed conduit can include an elongated probe, an artificial light source illuminating the conduit, and a microlens array mounted to the probe. An imaging device can be in data communication with the microlens array.

An optical module is configured being provided with: a first case fixed to an implementation surface of an implementation substrate to cover an LD and an LD driver; a first filler filled in the first case to seal the LD and the LD driver; a second case fixed to the implementation surface of the implementation substrate to cover the first case in a state of not adhering to the first case; a third case accommodating the implementation substrate and the second case inside; and a second filler filled in the third case to seal the implementation substrate and the second case.

An endoscope processor includes: an acquisition circuit configured to acquire display size information on a display that is connected to the endoscope processor; a display condition setting circuit configured to set, according to the acquired display size information and properties of an imager of an endoscope that is connected to the endoscope processor, a monitor shift value representing an amount of shift between a first image and a second image corresponding to first image data and second image data, respectively, the first image data and the second image data each having parallax with respect to a same subject; and an image processor configured to shift the first image and the second image to generate display image data to be output to the display using the set monitor shift value.

An image pickup apparatus for endoscope includes: an optical unit having an incident surface and an emitting surface; an image pickup unit adhering to the emitting surface; an interposer where the image pickup unit is bonded to a first electrode of a first main surface; and an electric cable bonded to the interposer. The image pickup unit is smaller than the optical unit and the interposer in an outer size in a direction orthogonal to an optical axis. The image pickup apparatus for endoscope further includes a heat conductive resin with which a portion among the emitting surface, the first main surface, and a side surface of the image pickup unit is filled. The first electrode extends to a position where the first electrode is brought into contact with the heat conductive resin.

In an endoscope apparatus including a processor, the processor specifies the position of a specific region and sets a reference scale in a picked-up image that is obtained from the image pickup of a subject on which the specific region formed by auxiliary measurement light is formed. Then, the processor extracts a region of interest, determines a measurement portion, calculates a measured value obtained from the measurement of the measurement portion, on the basis of the reference scale, and generates a measured value marker using the measured value. Further, the processor creates a specific image in which the measured value marker is superimposed on the picked-up image.
