Patent ID: 8908014

Claim:
An optical imaging lens system with double optical paths, comprising: a first optical subsystem; a second optical subsystem having a back focal length equal to that of the first optical subsystem; an optical path selector selectively having either a light reflection state or a light passing state at any given time; a first reflector set disposed at an image side of the first optical subsystem for directing light from the first optical subsystem to the optical path selector; a second reflector set disposed at an image side of the second optical subsystem for directing light from the second optical subsystem to the optical path selector, and a sensor for receiving images coming from the first optical subsystem and the second optical subsystem in sequential, alternating order; wherein when the optical path selector is in the light reflection state, 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 when the optical path selector is in the light passing state, 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.
