Single Photon LiDAR
HOW IT WORKS
Single Photon LiDAR provides the most efficient approach to rapid, high-resolution 3D mapping. SPL requires only one detected photon per ranging measurement, as opposed to hundreds or thousands of detected photons per ranging measurement for conventional or Geiger Mode airborne LiDARs. The higher efficiency of the SPL offers more 3D mapping capability in terms of swath, spatial resolution, acquisition time and density of range returns. Sigma's ability to rapidly deliver 3D data over thousands of square kilometers is changing the way we observe and analyze Earth.
Single photon sensitive 3D imaging LiDARs have multiple advantages relative to conventional multi-photon LiDARs. Their high efficiency enables orders of magnitude more imaging capability for a given laser power-receive aperture product. In our Single Photon LiDARs (SPLs), single photon sensitivity is combined with timing receivers having nanosecond recovery times and a multistop timing capability per pixel. These characteristics enable our LiDARs to operate under conditions of full solar illumination and to penetrate semiporous obscurations such as vegetation, ground fog, thin clouds, etc. Also, the use of green (532 nanometer) laser proves to offer additional capability for water penetration (bathymetry) as the SPL is able to routinely measure the surface of the water as well as the topography below the water.
SPL Applications
With the rising trend of LiDAR usage for commercial applications, Sigma Space’s SPL systems will allow decision makers access to high resolution 3D data easily and more frequently.
Sigma Space's SPL systems provide high resolution 3D data used by decision makers across industries. SPL cost efficiency and speed provides affordable and timely information in a wide-area scale previously unavailable. For the first time, evaluation of 3D change in a dynamic manner is possible with survey grade accuracy, high spatial resolution and State-wide area scale. Sigma Space's vertically integrated data acquisition-to-final product enterprise is currently providing 3D terrain and infrastructure data products to government and commercial customers. Sigma Space has capabilities in instrument design and fabrication, operation and data delivery. Our ability to service one or all capabilities allows us to provide the most cost efficient and flexible solution to our customers.

Micro Pulse LiDAR
www.micropulseLiDAR.comHOW IT WORKS
Micro Pulse LiDAR (MPL) is a sophisticated laser remote sensing system that provides continuous, unattended monitoring of the profiles and optical properties of clouds and aerosols in the atmosphere. Based on the same principle as radar, MPL transmits laser pulses that scatter (reflect) off particles in the atmosphere. MPL then measures the intensity of backscattered light using photon-counting detectors and transforms the signal into atmospheric-information in real time.
Sigma Space has been manufacturing MPL systems since 2004 providing high-resolution aerosol profiling, optically robust and resistant to misalignments, low-maintenance and optimized laser, continuous and autonomous data collection all the while being operational within minutes. Those who can benefit from MPL technology are meteorologists, atmospheric and environmental researchers and regulators, airports and air traffic controllers, and wind farmers. MPL Technology can enhance weather and air quality forecasts, improve models and emissions estimates by determining the extent of manmade and natural aerosols and measuring PBL height and trends, optimize aviation safety through enhanced cloud and volcanic ash profiling as well as help improve wind pattern forecasts for site evaluation and management.
