Embodiment Construction

[0020] Figure 3A is a cross-sectional view of an exemplary endoscopic imager 300 configured for side-looking endoscopy, and Figure 3B is a plan view of an exemplary endoscopic imager 300 configured for side-looking endoscopy. Figure 3A and Figure 3B The views of are parallel to the x-z plane and the x-y plane of the coordinate system 398, respectively. Herein, references to coordinate axes are the x-axis, y-axis, and z-axis of coordinate system 398 unless otherwise stated.

[0021] The endoscopic imager 300 includes a camera module 320 , an illumination unit 330 , and a specular reflective surface 340S that deflects the output of the illumination unit 330 and deflects the light toward the camera module 320 .

[0022] The camera module 320 has an imaging lens 322 with an optical axis 322X. The specularly reflective surface 340s forms an oblique angle 341 with the optical axis 322X. Angle 341 is, for example, 45±5° or 45±20°. Illumination unit 330 has a light emitting re...

Abstract

An endoscope imager includes a system-in-package and a specularly reflective surface. The system-in-package includes (a) a camera module having an imaging lens with an optical axis and (b) an illumination unit. The system-in-package includes (a) a camera module having an imaging lens with an optical axis and (b) an illumination unit configured to emit illumination propagating in a direction away from the imaging lens, the direction having a component parallel to the optical axis. The specularly reflective surface faces the imaging lens and forming an oblique angle with the optical axis, to deflect the illumination toward a scene and deflect light from the scene toward the camera module.

Description

technical field [0001] The present application relates to an endoscopic imager, an endoscope having the imager, and an endoscopic imaging method. Background technique [0002] Endoscopes are medical diagnostic instruments used to image cavities in a patient's body. It includes a flexible shaft that can be inserted into the patient's body through an orifice in the patient's body. The shaft has an end that includes a light source and a camera for illuminating and capturing images of the patient's part, such as a body cavity or organ, respectively. An endoscope has a field of view by means of a camera. An endoscope having a viewing window through the end of the tip is an endoscope. An endoscope with a viewing window through the side of the tip is a side-viewing endoscope. [0003] 1 is a cross-sectional view of a chamber 190 including a lesion 192 imaged by an end-looking endoscope 110 and a side-looking endoscope 120 . Lesion 192 is on chamber side wall 191 . In the cros...
