Underwater Camera: Eyes for exploring the underwater world

Underwater Camera: Eyes for exploring the underwater world

The working principle of underwater cameras is similar to that of ordinary cameras, but it also needs to adapt to the special requirements of the underwater environment. It usually uses an optical lens to collect light and image the object on the image sensor. The image sensor then converts the light signal into an electrical signal or a digital signal, and stores or transmits the image data after signal processing. In order to deal with problems such as underwater light refraction and scattering, underwater cameras often use special optical lens designs, such as anti-distortion wide-angle lenses, to ensure clear and distortion-free images. At the same time, some underwater cameras are also equipped with infrared lights or white light lights to provide illumination in low light or dark environments.

Fiber optic gyro compass: accurate core equipment for intelligent ship navigation

Fiber optic gyro compass: accurate core equipment for intelligent ship navigation

In the ship navigation system, accurate and stable acquisition of the true north direction reference is the core prerequisite for ensuring navigation safety and improving operational efficiency. As an iteratively upgraded inertial navigation device, the fiber optic gyrocompass abandons the disadvantages of high-speed rotating components of traditional mechanical gyrocompasses. It relies on the Segnac effect and fiber optic sensing technology to achieve synchronous and accurate measurement of true north heading and ship attitude with the core advantages of no wear, high precision, and fast start. It has become the mainstream navigation equipment for large merchant ships, maritime official ships, scientific research vessels, and military vessels, and provides reliable technical support for complex scenarios such as ocean shipping, polar scientific research, and dynamic positioning.
