    • A dual focal length optical system includes a first optical system and a second optical system. The first optical system is positioned along an optical path and includes an optical structure having an object side surface and an image side surface. The first optical system also includes a first surface of an intermediate reflective element located between the object side surface and the image side surface of the optical structure as viewed along the optical path. The first optical system has a first focal length. The second optical system shares a portion of the same optical path and includes a second surface of the same intermediate reflective element as that of the first optical system. The second optical system has a second focal length. The first focal length of the first optical system is longer than the second focal length of the second optical system.
    • 双焦距光学系统包括第一光学系统和第二光学系统。 第一光学系统沿着光路定位,并且包括具有物体侧表面和图像侧表面的光学结构。 第一光学系统还包括位于光学结构的物体侧表面和像侧表面之间的中间反射元件的沿着光路观察的第一表面。 第一光学系统具有第一焦距。 第二光学系统共享相同光路的一部分,并且包括与第一光学系统相同的中间反射元件的第二表面。 第二光学系统具有第二焦距。 第一光学系统的第一焦距长于第二光学系统的第二焦距。

    • Imaging systems and methods for calibrating imaging systems are provided. The imaging system has a body, a scene image capture system that captures images using a taking lens system that can be set to a plurality of different focus distances, and a rangefinder that is capable of determining a distance between the imaging system and at least one portion of a field of view of the taking lens system. The method comprises: automatically capturing a first calibration image of a first field of view through the taking lens system with the taking lens system set to a first focus distance setting; identifying a portion of the first calibration image having a predetermined degree of focus; using the rangefinder to determine a first calibration distance from the imaging device to the identified portion. A focus correlation is determined based upon the first calibration distance and the first focus distance setting.
