MEMS Optical Microphone
The CEKO Sensors range of audio microphones are the only all-optical frequency modulated sensors actually capable of measuring audio level pressures.
MEMS Optical Accelerometer
CEKO Sensors produces a wide range of high sensitivity accelerometers for low, medium and high frequency applications.
Technology
The all-optical MEMS sensor technology is typically implemented in the form of an accelerometer, but it is applicable to a number of related sensor concepts including pressure sensors, microphones, force sensors, temperature sensors, strain sensors and chemical sensors. The technology is based on reflection of light from a Bragg grating structure, however, using a completely different physical principle than FBG sensors. This concept allows for significant improvements in sensor specifications. It is at the same time compatible with existing FBG systems.
