  • Periscope optical module
    Patent number: 11579397
    Abstract: A periscope optical module is provided. The periscope optical module includes a first optical element, a second optical element, and a third optical element. The first optical element has a first optical axis. The second optical element corresponds to the first optical element and adjusts a forward direction of a light. The third optical element has a second optical axis. The third optical element corresponds to the second optical element. The light passes through the first optical element, the second optical element, and the third optical element consecutively. The first optical axis is not parallel to the second optical axis. A minimum size of the first optical element in a direction that is perpendicular to the first optical axis is larger than a maximum size of the third optical element in a direction of the first optical axis.
