Two Axis Electro Optical Sensor

Two Axis Electro Optical Sensor

A two axis electro optical sensor is a type of photoelectric imaging sensor used to measure the linear velocity of moving objects. This type of sensor has two axes and a lens, and it is commonly used in industrial applications such as line-of-sight control, machine vision, and factory automation. The two axes of the sensor can be used to measure a variety of linear motion variables, including accelerations, velocity, and position. This sensor is typically a high-precision, robust device that can be used in applications where precision and reliability are critical.

The two axis electro optical sensor is primarily used to monitor structural elements that generate, distribute, or convert electrical power; they are also found in structures that transport or convert oil and gas. They are generally categorized as passive or active sensors, depending on whether they reflect light from the surrounding environment or emit their own light directly. Optical sensors can be used to monitor various types of electrical equipment, such as wind turbines, railways, airplane wings, and ship hulls.

In the present paper, a three-dimensional target measurement error model of two axis electro optical sensor is established. Using simulation analysis, it is found that the target measurement error exhibits a spatial free-form surface with random irregularities, which can be significantly reduced by applying an active compensation technology to the sensor. Three error compensation methods are proposed: the LS-based method, the AKF-based method, and the RBFNN-based method. Simulation results reveal that the RBFNN-based method can more accurately approximate the error space surface and achieve more precise error correction, thus enhancing the target measurement accuracy of the two-axis electro-optical sensor.

TS01C is a high-precision, multi-functional two axis gyro stabilized dual-sensor electro-optical pod mounted on UAV and other moving platforms to search, observe and track ground targets day and night. It is equipped with a 30X optical zoom visible camera and a high-resolution uncooled longwave infrared sensor, with integrated gyro stabilization platform and 360deg continuous rotation servo motor. It can perform line-of-sight control and eliminate the vibration of the carrier platform through gyro stabilization system to realize the function of search, observation, tracking, recognition, and positioning.

Northrop Grumman Corporation (NYSE: NOC) has developed the LRS-2003, a new tactical-grade two-axis rate sensor that is optimized for platform and gimbal stabilization; electro-optical/infrared and radar gun and turret stabilization; and remote weapons stations. It is the smallest digital rate sensor in the company’s portfolio, and it is ideal for a wide range of military platforms. The LRS-2003 is the first production unit of a series of compact rate sensors designed to support multiple missions. Its small size makes it a great fit for UAV, missile, torpedo, and ground vehicle applications. The sensor’s high accuracy and reliability ensure accurate, time-critical control of a wide variety of military platforms. It is available for immediate production.
