According to reports, Imec, the world's leading research and innovation center for nanoelectronics and digital technology, announced on January 25, 2018 that it will showcase its first shortwave infrared (SWIR) at the SPIE Photonics West in San Francisco in February. ) Band hyperspectral imaging camera. The camera integrates a CMOS-based spectral filter and an InGaAs-based imager, thus combining the compact and low cost of CMOS technology with the spectral range of InGaAs.
Over the past five years, CMOS semiconductor hyperspectral image filters designed and manufactured by Imec have been applied in a monolithically integrated manner to silicon-based CMOS image sensors with visible and near-infrared light (VNIR) in the 400 to 1000 nm band. . However, it is expected that more than half of commercial multispectral and hyperspectral imaging applications will require short-wave infrared (SWIR) spectral data from the 1000-1700nm band.
Andy Lambrechts, project manager of integrated imaging at Imec, believes that “the SWIR band is the key to hyperspectral imaging because it provides valuable quantitative information such as organics and inorganics in foods, plants, human tissues, and pharmaceutical powders. Water, fat, lipid and protein content, as well as key distinguishing characteristics of plastics, paper, wood and many other materials, Imec leverages its core capabilities in the design and manufacture of optical filters, and to ensure complex, sturdy, compact types The low-cost hyperspectral imaging system solution has been delivered steadily, and the accumulated technical expertise has been able to extend the supply of its products to the SWIR band.â€
Imec's first SWIR band hyperspectral imager not only has 32 to 100 or more spectral band linear scan “ladder filter†designs, but also supports a snapshot mosaic solution that can capture 4 to 16 bands in real time at video capture speeds . This hyperspectral imager with USB 3.0 and Ethernet (GIGE) interfaces is currently being certified with strategic partners.
Jerome Baron, business development manager for integrated imaging and vision systems at Imec explained, “The InGaAs imaging industry is at a turning point in development. The market has gradually realized that the SWIR band hyperspectral imager has exceeded the military’s development prospects in many applications. In traditional niche areas such as remote sensing and science and technology, for a research institute such as Imec, it is just right to develop a compact, low-cost, robust hyperspectral imager in the SWIR band.Imec's goal is to be the most price-sensitive in this technology. Promotes product business in markets that include food sorting, waste management and recycling, industrial machine vision, precision agriculture, and medical diagnostics."
Imec's first SWIR band hyperspectral imager will be on display at SPIE Photonics West on February 1, 2018. The booth is located at #4321 North Hall in the center of Moscow, San Francisco.
