Whether we are developing sensors for the 21st Century Warfighter, designing systems to keep pedestrians safe, formulating low-temperature obscurants, detecting fires, or measuring fuel additives, we continually evolve to meet our own expectations in delivering state-of-the-art services.

 

Data Collection & Analysis

Data Collection & Analysis

Being sensor experts, we are often called on to support our customers in a variety of data collection and analysis exercises. This may include the collection of calibrated laboratory data, an outdoor collection of data from our facilities overlooking downtown Huntsville, “around the town and on the move” data collection, or customer sponsored field tests around the globe. Polaris has supported a large number of field tests for our customers including ARL, ONR, AFRL, MDA, JIEDDO, DOE, CERDEC, AMCOM, and OSLI. Our staff has experience in configuring and operating a large number of sensors under high-stress situations in a variety of operational environments in order to capture target data ranging from tanks, ships, and missiles to pedestrian traffic, automobiles, oil spills, and even wildlife.

Optical System Development

From Concept to Design
From Modeling and Analysis to Prototyping

Sensor prototyping has been one of Polaris’s primary business areas for over 10 years. Today, our prototyping process starts with a scientist and systems engineer who work together to define the concept that best meets the customer’s requirements. As the concept matures, additional optical, mechanical, electrical, and/or software engineers are tasked as needed to conduct a custom design and to transition that design into a system that best meets the customer’s needs. Throughout the process, Polaris works closely with the customer to ensure the best possible performance within the program’s budget. Our customer base for sensor prototypes is broad and includes all the military branches, the Departments of Energy, Transportation, and Homeland Security, the FBI and Intelligence Community, government research laboratories, universities, prime contractors, and various commercial industries. Our team has the knowledge and capability to design and build a wide range of sensor prototypes for whatever the application.

 


 

Image Processing and Software Development

Polaris utilizes an in-house software team to develop all sensor software and algorithms for its products and solutions. With a wealth of knowledge across the defense and commercial industries, our algorithm development team solves difficult image processing problems with novel algorithms implemented in efficient, high speed processors on board our sensors.

Our image processing experience includes:

  • Neural Network embedded processors for high speed, in time decision making
  • Radiometric and polarimetric processing
  • Particle filtering for target detection
  • Signal-to-noise ratio optimization
  • Kalman filtering and EKF/UKF variants
  • Simultaneous localization and mapping (SLAM)
  • Stereo vision

Calibration and Characterization

In order to effectively deliver quality imaging systems, Polaris carefully calibrates and characterizes each of our sensor products before they are shipped to our customers. Polaris has developed a series of precise techniques for calibrating a wide range of optical sensor systems. In particular, our staff has developed processes to calibrate the following types of sensors:

  • Cameras (Visible, LW, MW, SW)
  • Stereo camera systems
  • Multi-spectral imagers
  • Polarimeters
  • Optics (polarizers, filters, lenses, windows, cold plates)
  • Thermal systems

Our skills for calibrating these types of sensors include:

  • Detector performance characterization
  • Noise measurement (SNR calculation)
  • Stray light measurement
  • Distortion correction/removal
  • Detector alignment
  • Image registration
  • Non-uniformity correction
  • Polarimetric calibration
  • Radiometric calibration
