Infrastructure & Transportation
As our towns and cities become smarter, and mod-cons demand a higher level of connectivity, technology is quickly progressing to keep up with innovations. Thanks to the ideology of the Internet of Things (IoT), the last decade has witnessed even further technological growth and has seen us become more connected with the objects that surround us within the built environment. This connectivity has led to an even greater need for optical components within town and city infrastructure as more and more of these ‘objects’ join the IoT network.
Optics currently ordered:
Our optical components feature in several airborne and ground-based technologies under the Infrastructure, Transportation & Security brackets including:
- Cash machines and coin/note scanners
- Barcode scanners
- Facial recognition and biometrics
- Security cameras
- ANPR/ALPR (automatic number plate recognition/automatic license plate recognition) cameras
- Autonomous driving
- Solar-powered vehicles such as ships and electric cars
- Unmanned aerial vehicles (UAVs) for surveillance
- LiDAR within construction
- 3D mapping lasers
- Optical payloads for satellites
- Monitoring sensors.
Our need for timesaving convenience has led to the likes of cashier-free smart shopping and autonomous driving as well as unmanned aerial vehicle (UAV) logistics. These novelties, of course, all employ optics for sensors, computer vision technology and light detection and ranging (LiDAR) systems. There are, however, additional optics-based, behind-the-scenes technologies to consider that enable optimum operation. Such innovations include concepts like ‘smart cities’, which strategically tackle rapid urbanisation by using IoT sensors to collect data.
Sensor-based technology appears to be leading the way in enhancing infrastructure operations and enabling everyday functions to display a ‘smart’ label. One example in the UK is Highways England’s rollout of ‘smart motorways’ which uses sensors and CCTV as part of an active traffic management (ATM) method to monitor traffic volumes; aiming to improve efficiencies and decrease congestion on roads. Often, smart motorways are also equipped with vehicle detectors as part of a MIDAS (motorway incident detection and automatic signalling) system, which can feed information back to the displays for variable speed limits.
As well as ensuring roadways function effectively, sensors are also deployed across areas of towns and cities for applications such as smart parking, the monitoring of tunnels, bridges and roads and waste management.
Here at Knight Optical, we offer an array of optical components for integration with sensors. Whether your application works in the UV or IR spectrum, we have a range of optical components suitable for a variety of devices. These include optical filters (such as interference bandpass, narrow bandpass, neutral-density [ND], longpass and shortpass options), front surface mirrors, collimators prisms and beamsplitters where engagement with multiple detectors is required.
Security plays a crucial role in monitoring zones, keeping residents safe and deterring potential thieves. Cameras are a vital cog in the wheel for connectivity within infrastructure and ensuring optimum operation within these systems is essential. Opting for premium quality on-spec optical components enhances a camera’s longevity and operation; delivering a long-lasting and reliable device. Not only do we supply spearheads within the field with metrology-tested optics, but we are also a go-to resource for many manufacturer’s optical queries; whether it be prototyping or mass production. So, if you have a query regarding the optics required for your CCTV application, please do not hesitate to get in touch.
As well as CCTV, we also have long-standing relationships with many operating within the ANPR/ALPR sectors. Common optics specified for these industries include interference bandpass filters, aspheric lenses and protective windows (including BK7 [or equivalent], germanium and sapphire material options).
Much like the roadways sector, the railway industry shares many similar technologies such as smart ticketing and traffic management systems. CCTV and sensor-based methods of monitoring are commonly found within the field and include examination through the form of cameras for the observation of tracks and overhead cables as well as infrared sensors used for track deviation.
Here at Knight Optical, we offer a range of infrared and UV materials for use within rail monitoring applications; including filters, prisms and mirrors — plus many more. If you are uncertain on the optical components or wavelength range required for your project, please contact a member of our technical team today.
Technology has played a huge role in simplifying the airport experience, and methods such as high-definition cameras for biometric identification and all-electric vehicle assistance have been introduced in the UK recently. CCTV is also high on the technological agenda to safeguard passengers and monitor the airport zones.
As well as supplying optical components for CCTV use within the airways industry, we also provide a range of optics for precision approach path indicators (PAPIs) to provide visual aid on runways. These include dichroic colour filters, parabolic reflectors and bespoke lens assemblies.
Our optical components are also employed for marine use within many technologies that are also found in mainland areas and in airborne applications. Port management is frequently turning to technological innovations for increased efficiency within operations, and forward-thinking ports are opening up to the possibilities offered by developments such as remote-controlled cranes and LiDAR-powered autonomous trucks. While out at sea, real-time remote vessel tracking is also being used to track and monitor a vessel’s movements.
