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.
