Read Article”This is an IP company with a new technology concept. Photodiodes are semiconductor devices that respond to light by generating an electric current. Over the decades, their technology and design have improved but the fundamental concept remained the same. The device operates in a static way. A constant voltage is applied, and the resulting photocurrent is measured to infer light intensity. This is not the case for dynamic photodetectors, which use a different approach.
