ADAS camera optical alignment and testing in mass production to meet requirements of tomorrow

Advanced Driver Assistance System (ADAS) technologies increase the demand for high-quality machine vision systems and optical sensors. As these technologies mature, imaging systems are required to enable better optical performance. Reduction in pixel size and an increase in pixel density of modern image sensors make it difficult to align optical lenses and sensors with the required precision. This presentation describes the latest achievements in actively aligning a lens and camera sensor for optimal image quality. The theoretical limits of accuracies determined by the physical properties of lens and sensor are compared with examples from practice.  This presentation describes the latest achievements in actively aligning a lens and camera sensor for optimal image quality. The theoretical limits of accuracies determined by the physical properties of lens and sensor are compared with examples from practice. In addition, the requirements an active alignment system must meet to achieve the best possible accuracy and repeatability for the alignment process are described.
