Nanohmics has developed a process for fabricating an anti-reflective (AR) surface treatment by applying randomly-placed, size-controlled surface relief structures onto infrared windows and lenses. The structures on the surface of the component are smaller than the wavelength of light and provide a refractive index gradient between the air and the medium. This process creates optical windows with improved transmission over 2 octaves of spectrum and with an incident angle of 0°- 65°. The ability to apply this AR treatment to curved surfaces enables its use in complex optical systems. It also provides better laser damage resistance compared to multi-layer dielectrics.
Argus - Laser Threat Detection Sensor
High Energy Laser weapons are being developed and deployed to disrupt UAS Intelligence, Surveillance, and Reconnaissance (ISR) missions. Our sensor provides real-time identification, characterization and geolocation of laser threats. This information will help determine who is targeting the aircraft, allowing the pilot to deploy the proper countermeasures. Argus can detect and identify both continuous and pulsed High Energy Lasers.
The system contains a small external optical sensor and an interior electrical board assembly. When laser threats are detected, it will send a threat packet to the pilot via the unmanned aircraft system’s existing data network. This information will enable the pilot to determine the type of threat they are facing and what they should do about it. Argus can be installed in either the fuselage or the wings of small to medium sized aircraft.
This active refrigeration unit allows temperature sensitive materials to be transported through environments where users might experience power interruptions. The system features a unique payload area surrounded with phase change material (PCM) to keep the payload at constant temperature. A compressor-based refrigeration system provides active cooling when power is available and directly charges the PCM. Additionally, the payload and PCM are insulated with a high-R-value polyurethane foam.
Plenoptic Wavefront Sensor
Our passive, extended-scene wavefront sensor was designed to make high dynamic range wavefront distortion measurements using only scene imagery without the assistance of a point-source beacon. When integrated into adaptive optics systems it provides real-time measurement of optical aberrations including misalignment, static optical defects, defocus, and atmospheric turbulence induced aberrations.
Unlike Shack-Hartman sensors, which are positioned at the pupil plane, Nanohmics wavefront sensor is placed in the optical system’s focal plane. Our plenoptic architecture allows the measurement of differential shifts between subaperture images which are then used to calculate the wavefront with high accuracy. This architecture also eliminates the possibility of cross talk between subapertures and provides a large figure dynamic range. Real-time wavefront sensor computations are performed by proprietary software executing on a Graphics Processing Unit (GPU).
Water Toxicity Test
A field portable, cell-based biomonitor that identifies whole water toxicity using a direct measurement on a living organism’s reaction to one or more potentially toxic compounds in water. It doesn’t tell you everything that is in the water, but gives an indication that something is wrong.
Inside each biochip is a layer of live fish cells covering an electrical circuit. When water containing toxic chemicals is added to the biochip, the physical structure of the cells change in ways that we can measure electrically. Inside the instrument, a detection algorithm compares the control and test sample with historical data to determine if the sample is toxic. The instrument displays a simple “safe” or “contaminated” result in 60 minutes or less.
