Optical Detectors & Sensors are optoelectronic components that convert incident light into an electrical signal for measurement, monitoring, or control. They provide a standardized interface between optical energy and electronic circuits, enabling reliable detection of light presence, intensity, or changes over time.
This category broadly includes devices based on different photoelectric conversion principles, such as:
- Photodiodes for light-to-current conversion
- Phototransistors for light-controlled signal amplification
- Photoresistors for light-dependent resistance variation
- Ambient light and color sensors for optical sensing and signal output
Optical detectors and sensors are commonly selected based on their sensing method, output behavior, and compatibility with electronic signal processing, forming a foundational building block within optoelectronic system design.
