1. Introduction

Single-axis digital fiber optic gyroscope offers significant performance in critical areas such as bias stability, bias repeatability, scale factor, and maximum input rate.

2. What is a single-axis digital fiber optic gyroscope?

A single-axis fiber optic gyroscope (also known as a single-axis optical gyroscope or simply a gyro) has only one axis of rotation (e.g., 0 to 30o), and it measures the angular position of an object in three dimensions. This type of device can be used in many applications, including:

  • Helmets
  • Refrigeration systems
  • Headaches
  • Thermal management systems
  • Cameras that can be used on airplanes
  • Motion capture systems that require high accuracy and repeatability (e.g., video game controllers)

This means that a single-axis gyroscope—assuming they have the requisite hardware—can perform any task your product will need to perform: from tracking objects in 3D space to detecting motion with high accuracy and high repeatability. This makes them an attractive solution for many different types of products: start-ups looking for growth; established companies needing more functionality; businesses looking for cost savings; hobbyists seeking low-cost devices; etc… Here are some products worth mentioning:
Noise cancellation – It requires no extra hardware and its small size makes it ideal for use in consumer electronics such as cell phones, cameras, toys, watches… However, some consumer electronics manufacturers may not allow its use due to concerns about electromagnetic interference. In addition to noise cancellation, this type of gyroscope can also be used as a white balance calibration tool since it will automatically correct for any color tinting caused by light reflected from the screen or other objects in the room. This device will work great with most digital cameras because they usually have noise-reduction capabilities built into their chips. In addition, as with most applications where color correction is necessary—such as photography—this type of gyroscope can be used without additional software adjustment since its firmware adjusts automatically based on the camera’s settings and color temperature characteristics. Most digital cameras also have automatic white balance capabilities which do not require manual adjustment using this type of gyroscope.

4. How a single-axis digital fiber optic gyroscope works.

The problem with gyroscopes is that they do not measure the output of the tip’s movement as a whole. Instead, they measure only one axis (x, y, or z). For example, a gyroscope measuring x-axis direction yields an output signal at a rate of 2 Hz (Hz = Hertz), but it does not yield an output signal for the y-axis, which is 1 Hz. Thus, if the y-axis value is zero (y=0) and x=2Hz (or 0Hz), then the output from one axis should be zero. Gyroscope outputs can be negative if either of the axes are positive.
A single-axis digital fiber optic gyroscope from a China factory uses electronics to convert input signals into relative movements in three axes: x-, y-, and z-. The electronics also convert this relative movement into absolute positions in each axis. The movement can then be mapped onto a sensor that has physical dimensions to follow and provides feedback on the device’s orientation. The motor controller should be able to switch between two different orientations based on the horizontal position of the sensor—for example, using X.Y scaling or YZ scaling—with no loss of accuracy.
The China single-axis digital fiber optic gyroscope manufacturer is used in applications where high performance is needed in critical applications such as high-precision angular orientation and stability control for spacecraft and satellites, as well as military applications such as guidance systems for missiles and unmanned aerial vehicles (UAVs), ranging from small kids’ toys such as remote control helicopters to full-scale space launch vehicles (SLVs). One type of application uses a single axis fiber optic gyroscope to provide a highly precise linear guidance system for large spacecraft such as Manned Orbiting Astronaut (MOA) vehicles designed for space missions around Earth; another type uses low bias stability and accuracy because it has only one axis instead of three axes with gyroscopic sensors providing feedback on all three axes; yet another type uses long life sensors with limited temperature sensitivity and high sensitivity so that it can provide high performance without frequent changeover cycles; yet another type uses lenses or mirrors to focus or deflect light so that it can provide precise high resolution positioning without any changes to power supply requirements even when experimenting with various combinations of sensors; yet another type provides high precision positioning at very low cost because there are no moving parts in its design.
