In this video you can see repeatability and sensitivity of this acceleration measurement sensor.
Video description:
Repeatability of this sensor can be seen on the optical power meter (right) by the comparison of the values in dBm at the initial still state (at the beginning of the video it stands at about -20.2dBm) and at the final still state (at the end of the video where it stands at about -20.3dBm). During first acceleration movement to the left the value on optical power meter goes up to about -14dBm and during deceleration to the left it goes down to about -34dBm and than at the still state it goes back up to about 20.2dBm. Then when it accelerates to the right the display shows value of -29dBm, when it decelerates to the right it goes down to about -15dBm and so on. At one point you can even see value of -43dBm. This is due to the fact, that the speed of the display is too slow so that the values on the display do not correspond exactly with the acceleration/deceleration changes of the sensor.
Sensitivity of this acceleration/deceleration sensor is set for medium level, however, it can be customized for much higher or lower levels of sensitivity, i.e. this value of sensitivity can be adjusted according to the intended application.
Usability of this racceleration/decelerationsensor is widespread as its sensitivity and ruggedness are highly customizable.
Applications of this acceleration/deceleration sensor can be seen in the following:
- construction industry (high-rise buildings, bridges, tunnels …)
- geological/earthquake monitoring
- large mechanical equipment (turbines, ….)
- transport industry (high-speed trains, ships, planes, cars, ….)
via the usage of “additional” software for acceleration/deceleration recording and processing, it can be used for autonomous navigation system in transport industry (ships, submarines, planes …) or in conjunction with rotational acceleration sensor for turning optimization in racing car industry
Further advantages of this sensor are:
- low energy consumption
- highly customized sensitivity
- different level of ruggedness
- electromagnetic compatibility (EMC)
