The Armasight Helios line is the latest and most technologically advanced family of thermal imaging bi-oculars on the market today. Bi-ocular design is better for sustained viewing periods and improved depth perception. The Helios product line is based on the latest FLIR Tau 2 VOx microbolometer core, and includes a variety of different models, each optimizing performance, price, and state-of-theart technology for a variety of uses and mission applications. The Helios is a solid state, uncooled, long-wave infrared, magnified, dedicated handheld thermal imager intended for day and nighttime missions. The 24/7 mission capability is just one of the many strengths this product line has to offer. Thermal imaging technology also allows you to detect targets by cutting through snow, dust, smoke, fog, haze, and other atmospheric obscurants. Unlike the use of laser targeting or near-infrared illumination to augment night vision equipment, Helios thermal imagers are extremely difficult to detect with other devices, as they emit no visible light or RF energy. Armasight is convinced that the Helios thermal imaging bi-ocular represents one of the most sophisticated devices on the market today, due to its superior price-to-performance value.
special user-adjustable imaging tools
Active Contrast Enhancement (ACE) – a digital “Contrast” correction that allows for smart scene optimization based on dynamic adjustments, where a variety of contrast levels occur depending on relative scene temperature.
Second Generation Digital Detail Enhancement (DDE) – a “Sharpness” correction that digitally enhances the picture, significantly sharpens edges, and further reduces image noise.
Smart Scene Optimization (SSO ) – a fine-tuning computational correction that significantly improves overall visual acuity for targets that have thermal signatures similar to the surrounding background.
Information-Based Histogram Equalization (IBHEQ) – a “Sky/Sea” enhancement – information- based environment dependent algorithm that automatically adjusts camera gain and excludes pixels determined to not contain critical information. Specifically helpful in scenes with great expanses of visible sky or water.
User-Controlled Manual Non-Uniformity Correction/ Flat-Field Correction (UCMNUC/ FFC). There is a mechanical shutter between the camera sensor and the lens. This shutter is used to perform a non-uniformity correction (NUC), also known as flat-field correction (FFC). During FFC, the shutter presents a uniform temperature source to each detector element in the array. While imaging the flat-field source, the camera updates the offset correction coefficients, resulting in a more uniform image after the process is complete. All Helios models allow for user to manually trigger or interrupt scheduled UCMNUC/ FFC function.
Silent Shutterless NUC™ (SSN ) – In addition to User-Controlled Manual NUC/ FFC, all Helios models employ a digital, supplemental, non-mechanical flat-field correction that extends periods between mechanical shutter events and further reduces image noise. SSN is an always ON enhancement.
