ISI is a UK R&D company that designs and develops remote sensing instrumentation for use in hostile and high-temperature environments. Clients include National Grid, Xstrata, European Space Agency and ABSL Space Products. ISI was co-founded in 2010 by Directors Dr Michael Foster and Dr Jonathan Storey, with Nicholas Bantin. The Directors are renown worldwide as experts in Optical filtering systems, Laser-enhanced remote sensing instrumentation, Photon Counting Techniques and High-precision interferometry. Together, the Directors have developed a number of instruments in the field including the Solar Swedish Telescope CRISP (http://www.solarphysics.kva.se/crisp.html) instrument. The Directors have 10 years’ experience working with LIDAR and 3D vision systems for space-borne applications and are internationally respected in the community. ISI's core business is providing innovative solutions typically requiring laser-based remote sensing instrumentation in difficult environments targeted at the specific problem. ISI provides an end to end solution designing instruments, from an initial simulated concept through to bench top instrument development and then to the manufacture of a complete, working instrument. On-site, ISI has a range of optical, mechanical and electrical design tools including CAD and ray tracing facilities. In addition, the company has a fully equipped optical lab and dark room for testing new instrumentation.
