> Click on the "WEBSITE" link for more > Our Transport Consulting experts possess the knowledge, experience and skills to analyse the surrounding topography and the impact of abnormal loads & heavy transport projects on the surrounding environment. Collett Transport Consulting topographical surveys are used to map the contours of the ground and existing features to assist with route planning and necessary modifications for abnormal load & heavy transport projects. This process, undertaken in the early days of our planning allows us to identifying any features which which could potentially impact on any abnormal load or heavy transport projects. The data gathered by Collett Transport Consulting from site visits and swept path analysis, coupled with data gathered during topographical surveys, provides the most accurate indication of any third party land requirements, road widening or pinch points along the route.

Knight Optical offer a range of Stock Sapphire Windows, and custom for use within Airborne LiDAR Systems. These are systems used in surveying for topographical measurements. The data accumulated can be used to generate a Digital Terrain Model or a Digital Elevation Model which are 3D representations of terrain. Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm. Making it ideal as a protective window for airborne systems which may be utilised in harsh environment or against birds! Sapphire is grown by various methods from seed samples. Sapphire can be polished to a high standard, but as it is the second hardest mineral on Earth it must be subject to high forces to polish. Therefore, windows made from Sapphire must have a thickness to diameter ratio of at least 10:1, that is, greater For more information read PDF….

> Click on the "WEBSITE" link for more > Our Consulting Team has a proven track record in providing specialist reports to facilitate safe and professional transport. Our team of highly trained, experienced professionals can analyse the impact of abnormal loads on the surrounding environment identifying any amendments which may be required for safe passage. Possessing detailed knowledge of our specialist tractors, trailers and SPMTs, we apply the practical transport considerations of abnormal load vehicles. Our team understands the behaviour of abnormal load vehicles and has extensive knowledge of transport regulations, environmental considerations and planning requirements. For Heavy Transport projects we routinely undertake Route Access Surveys, Swept Path Analysis, Topographical Surveys, Traffic Management Plans, Visual Route Inspections, Test Drives and Environmental Impact Assessments.

HD Scanning Thermal Microscopy (HD SThM) allows studying local thermal properties simultaneously with QNM measurements. From the hardware point of view it was implemented using AppNano VertiSense™ thermocouple probes. The thermal conductivity and temperature mapping modes (CMM, TMM) can be realized by positioning the AFM laser at the end or the central part of the probe, respectively. HD mode working principle allows exceptional spatial resolution of SThM measurements in comparison to conventional Amplitude Modulation (AM) mode. That was demonstrated in TMM of a microheater sample. SThM and HybriD mode is the winning combination for distinguishing between the constituents of polymer blends as demonstrated in the example of a blend of polystyrene (PS) with low density polyethylene (LDPE) (see below). The difference in thermal conductivity of the polymers (PS – 0.12 W/mK; LDPE – 0.33 W/mK) allows the assignment of the colder matrix to LDPE and the hotter islands to PS.

Stateoftheart HybriD 2.0 Control Electronics incorporates highspeed digital lockin amplifiers (LIA) and phase locked loop detector (PLL) for advanced oscillatory resonance modes Amplitude Modulation with Frequency Imaging (AMFI) and Frequency Modulation (FM) modes. They provide exceptional level of spatial resolution of challenging flat and soft samples (selfassembled molecular structures etc.) thanks to ultraprecise control of the tipsample interaction force. Additionally they allow mapping of its mechanical properties. The two images below show topography and probe resonant frequency distribution over lamellar arrangement of short alkane C36H74 on graphite with a spacing of 4.5 nm. One can also see a couple of adsorbates formed on the lamellar surface by disordered alkane chains which are rarely observed by the traditional AM mode.
