OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, today introduced the Nighthawk Nyxel, a revolutionary near-infrared (NIR) technology. The technology successfully uses the new silicon semiconductor architecture and process to solve the current image sensor near infrared detection challenges. Compared to Howell's traditional near-infrared sensors, the Nighthawk Nyxel technology increases QE by up to 3X at 850nm and up to 5X at 940nm. These improvements in near-infrared sensitivity allow Howe's image sensors to image sharper and farther at the same amount of near infrared light and farther the imaging area can be detected. In the meantime, the Nyconel Nyxel imaging system reduces the need for LED lights in order to match the current system's low power requirements, reducing overall power consumption. With these benefits, Nighthawk Nyxel technology is suitable for many applications such as surveillance, automotive and machine vision cameras.
The current market for machine vision and night-vision camera applications rely mainly on near-infrared imaging because NIR imaging can capture objects beyond the visible spectrum; in addition, it helps prevent any visible light interference with the surroundings. In addition, with more NIR photons than visible photons at night, the Nighthawk Nyxel technology enables night-time and battery-powered security camera applications by enabling higher-resolution image capture at night without the need for many power-hungry LED lights The ideal solution. Previously, traditional near-infrared detection methods were far behind the high sensitivity required for automotive and security camera applications, as well as newer mobile devices and high-performance needs with embedded machine vision applications such as augmented reality (AR) and virtual reality (VR) product. Nighthawk Nyxel Technology delivers performance beyond existing near-infrared technology to meet the higher, more demanding requirements of next-generation applications.
"Conventional near-infrared imaging methods rely on thick silicon only to improve the sensitivity of near-infrared image sensors, however, this approach leads to crosstalk and lowers the modulation transfer function (MTF)." The industry generally introduced deep trench isolation (DTI) Try to overcome this, but the result often results in damage to the dark areas of the image. "Lindsay Grant, vice president, Process Engineering, Howe Technology explains," However, Howe Technology overcomes these challenges through exclusive collaboration with our foundry partners and The initial results are impressive with this technology on its 300mm wafers, which are now of great interest to our OEM customers. "
Nighthawk Nyxel Technology's principle is to combine a thick silicon pixel architecture with extended DTI to improve QE and then carefully manage the surface texture of the wafer to maintain the modulation transfer function without affecting the dark current of the sensor. Products Using Nighthawk Nyxel Technology Up to 3X QE at 850 wavelengths and 5x QE at 940nm with all other image quality indicators compared to OmniVision's traditional near-infrared products . These near-infrared image sensitivity improvements provide unparalleled high image quality, increased image detection range, and lower light source requirements for lower power consumption.
