Abstract (en)
[origin: WO2015110916A1] An optical zoom in a small form factor suitable for use in mobile devices such as cell phones, security cameras, and other small-scale imaging systems. One or more Alvarez lens pairs are provided, and moved transversely to the optical axis. The combination of one or more Alvarez lens pairs and the actuator permits a zoom power of at least 3x with a lateral displacement distance of the optical components of approximately five millimeters or less.
