Abstract
Methods and apparatus actively align a lens to a digital camera sensor. The lens includes a “floating” optical element. One or more test probes are temporarily electrically connected to electrical contacts, such as traces on a flexible printed circuit, of the lens. Motor control signals are injected via the test probes and the electrical contacts, so as to move the floating optical element to a predetermined position and maintain that position during the active alignment process.
