Today, even though most of us aren’t celebrities, we appear on camera more than ever before. Smartphones, computers, and other devices equipped with compact camera modules (CCMs) are almost inescapable — whether or not we feel ready for our closeups! As CCM-equipped products continue to rapidly evolve, these small but powerful optical devices must also keep improving. To ensure that CCMs can produce clear, sharp images within cost and spatial constraints, engineers can analyze their performance with optical ray tracing simulation. Read more
