Lens design for active alignment of mobile phone cameras

Modern mobile phones contain one or multiple high-resolution camera modules with miniature multi-element lenses. Active alignment of the lens and the image sensor is a common process improvement for the integration of mobile phone camera modules to increase manufacturing yields while maintaining high resolution. Active alignment of the image sensor can offer extra degrees of freedom in lens design optimization and thereby help lens designers offer lens designs with high nominal and as-built performance.
