Short-wave infrared (SWIR) may still be in its infancy. However, recognition of its potential to replace near-infrared scanners on smartphones is growing and a drive to integrate facial-recognition modules could be set to catapult this technology in the next five years.
That is according to the ‘SWIR Imaging 2023’ report, which delves into the current state of the SWIR imaging industry and provides a possible scenario for the future.
Yole Intelligence forecasts short wave infrared (SWIR) imaging will be a $2.9 billion market by 2028, up from $322 million last year with growth driven by the consumer segment. According to the firm’s analysis it expects to see SWIR systems being integrated with less-expensive smartphones and in AR/VR headsets for higher-performance tracking cameras. The main motivation for SWIR in 3D sensing is to integrate facial-recognition modules behind the OLED display, as these materials are more transparent in the SWIR band.
Axel Clouet, Ph.D., Technology and Market Analyst, Imaging at Yole Intelligence said: “In 2026, SWIR can start replacing NIR imagers in flagship smartphones for under-display integration of facial recognition modules. This will drive a US$2,074 million market by 2028, considering the complete 3D-sensing modules.”
Among its uses, short wave infrared (SWIR) imaging and illumination technology can be particularly useful for military and law enforcement in both night and daytime operational scenarios. Along with enabling nighttime operations, a secondary benefit of SWIR imaging is that it offers the possibility to capture images through tinted materials, such as tinted architectural, automotive glass or even sunglasses lenses.
Next generation SWIR sensors for mobile phones will also demand sensors operate at longer wavelengths for eye safety, solar compatibility and longer distance imaging.
So far, Sony and STMicroelectronics are the only traditional CMOS sensor-makers that have also developed SWIR imaging technology, the report said.
