In a fundamental sense, a sensor is a device that can measure a physical quantity or converts it into a signal. Ultrasonic sensors, also called transistors when they send and receive, work similar to RADAR as they interpret radio or sound waves. In military, medical or automotive industries, theses sensors can be used to detect the presence of a target or measure distance. Because these sensors detect sound rather than light, they are able to work in applications where their photoelectronic counterparts may not.
Sensor technology can be used for a wide variety of devices in many different industries: aerospace and defense, automotive, medical and high-end consumer technology.
Any type of sensor that carries high-precision or high-reliability requirements could be a candidate for a Palomar Technologies solution.
