Claim Text:
1. An apparatus for optical imaging lens system with multiple optical paths, comprising: a first optical subsystem; a second optical subsystem having a back focal length equal to that of the first optical subsystem; a reflector set disposed at image sides of the first optical subsystem and the second optical subsystem for directing the light from the first optical subsystem and the light from the second optical subsystem, so that an optical path of the first optical subsystem intersects with an optical path of the second optical subsystem; a movable optical path selector for reflecting either the light from the first optical subsystem or the light from the second optical subsystem; a sensor for obtaining a first image data from an image coming from the first optical subsystem and a second image data from an image coming from the second optical subsystem; and a calibration module for receiving the first image data and the second image data from the sensor; wherein the calibration module calibrates the first image data according to at least one selected optical parameter of the second optical subsystem and calibrates the second image data according to at least one selected optical parameter of the first optical subsystem with the selected optical parameters of the first optical subsystem and the second optical subsystem being different; wherein when the movable optical path selector is disposed at an intersection of the optical path of the first optical subsystem and the optical path of the second optical subsystem, the light from the first optical subsystem forms an image on the sensor while the light from the second optical subsystem forms an image on another position rather than on the sensor; and wherein when the movable optical path selector is disposed at a position other than the optical path of the first optical subsystem, the optical path of the second optical subsystem, or the intersection of the optical paths of the first and the second optical subsystems, the light from the second optical subsystem forms an image on the sensor while the light from the first optical subsystem forms an image on another position rather than on the sensor.
