Photonics Mast
A photonics mast (or ''optronics mast''BBC News Scotland, A vision of evolving technologies'' 30 August 2007, 13:06 GMT) is a sensor on a submarine which functions similarly to a periscope without requiring a periscope tube, thus freeing design space during construction and limiting risks of water leakage in the event of damage. A photonics mast replaces the mechanical, Line-of-sight propagation, line-of-sight viewing system with digital equipment, similar to a digital camera array, and it has fewer locational and dimensional constraints than a traditional periscope. Unlike a periscope, it needs not be located directly above its user, and it requires only a small submarine hull, pressure hull penetration for cabling. This allows the photonics mast to fit entirely within the Sail (submarine), sail of the submarine and means the control room need not be placed directly below the sail. A photonics mast operates by rising above the water in a manner similar to a telescoping (mechanic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photonics Mast Array 01
Photonics is a branch of optics that involves the application of light generation, generation, light detection, detection, and manipulation of light in the form of photons through Emission (electromagnetic radiation), emission, Transmission (telecommunications), transmission, modulation, signal processing, switching, optical amplifier, amplification, and photodetector, sensing. Even though photonics is a commonly used term, there is no widespread agreement on a clear definition of the term or on the difference between photonics and related fields, such as optics. Photonics is closely related to quantum electronics, where quantum electronics deals with the theoretical part of it while photonics deal with its engineering applications. Though covering all light's technical applications over the whole light spectrum, spectrum, most photonic applications are in the range of visible and near-infrared light. The term ''photonics'' developed as an outgrowth of the first practical semi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Borei-class Submarine
The Borei class, alternate transliteration Borey, Russian designation Project 955 ''Borei'' and Project 955A ''Borei-A'' (, NATO reporting name Dolgorukiy), are a series of nuclear-powered ballistic missile submarines being constructed by Sevmash for the Russian Navy. The class has been replacing the steadily retiring Russian Navy Delta III and Delta IV classes and fully retired (as of February 2023) , all three classes being Soviet-era submarines. Despite being a replacement for many types of SSBNs, Borei-class submarines are much smaller than those of the Typhoon class in both displacement and crew ( tons submerged opposed to tons and 107 personnel as opposed to 160 for the Typhoons). In terms of ''class'', they are more accurately a follow-on for the Delta IV-class SSBNs. History The first design work on the project started in the mid-1980s and the construction of the first vessel started in 1996. Previously, a short-lived, smaller parallel design appeared in 1980s with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Design work commenced in earnest in the 1980s with the first submarine built in the 1990s–early 2010s with commissioning in 2013. The first two boats to an upgraded (and slightly shorter overall) ''Yasen-M'' design were commissioned in 2021. Based on the and designs, the ''Yasen'' class is projected to replace the Russian Navy's current Soviet-era nuclear attack submarines as well as Oscar-class submarine, Oscar II class cruise missile submarines.

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Sōryū-class Submarine
The ''Sōryū''-class submarines (''16SS'') are diesel-electric attack submarines. The first boat in the class entered service with the Japan Maritime Self-Defense Force in 2009. The design is an evolution of the , from which it can most easily be distinguished by its X-shaped stern combination diving planes and rudders. At the time of launching, the ''Sōryūs'' had the largest displacement of any submarine used by post-war Japan. The Sōryū-class is Japan's first air-independent propulsion submarine class. From ''Sōryū'' to ''Shōryū'' are fitted with Kockums Naval Solutions Stirling engines license-built by Kawasaki Heavy Industries, allowing them to stay submerged for longer periods of time. The 11th submarine of the class, ''Ōryū'', is the world's first lithium-ion battery submarine. The cost of the sixth submarine (''Kokuryū'') was estimated at US$540 million. In 2023, the first of the replacements for the ''Sōryū''s, the , entered service. Naming convention Jap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SAGEM
SAGEM (, translated as "Company of General Applications of Electricity and Mechanics") was a French company involved in defense electronics, consumer electronics, and communication systems. Founded in 1924, SAGEM initially specialised in mechanical engineering and tool manufacture. Early in its existence, it entered the defense sector. The company made a foray into telecommunications in 1942 with the first telex printer, although it was principally a defense-oriented company during the first few decades of the post-war era. This majority focus upon the military sector continued for several years after the departure of Marcel Môme, SAGEM's founder. During the 1980s, SAGEM's distributed Japanese fax machines while developing its own technology. Over the traditional defense sector, such products accounted for a growing share of SAGEM's revenues. During the 1990s, the firm entered the automotive systems sector. Starting in 1997, the company produced GSM telephones for the French ma ...

Laser Rangefinder
A laser rangefinder, also known as a laser telemeter or laser distance meter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used instead. Laser rangefinders are sometimes classified as type of handheld scannerless lidar. Pulse The pulse may be coded to reduce the chance that the rangefinder can be jammed. It is possible to use Doppler effect techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast. Precision The precision of an instrument is correlated with the rise time, divergence, and po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
