TriEye Introduces First VCSEL-Based SWIR Imaging and Depth Sensing System

     TriEye is proud to announce the first-in-class VCSEL-based shortwave infrared (SWIR) imaging system. The system integrates a TriEye CMOS-based short-wave infrared image sensor and a VCSEL light source. This upgraded electro-optical (EO) system, combined with VCSEL technology, will enable the mass consumer market with advanced SWIR imaging capabilities.

     Paving the way for next-generation SWIR imaging solutions. The new optoelectronic system shown by TriEye matches the TriEye Raven SWIR image sensor with a 1350nm VCSEL light source from its partners, enabling the highest power density – currently in excess of 5 watts/ square millimeters. The optoelectronic system will provide significant value for short-range applications such as mobile devices, biometrics, industrial automation, and biomedical.

     The TriEye optoelectronic system is the world's first system solution that uses VCSELs as light sources for short-wave infrared imaging and depth sensing. VCSELs were first used in the communications industry and are now widely used as light sources in sensing applications around the world, but have not been successfully integrated into short-wave infrared sensing systems and are limited to the visible-near-infrared (VIS-NIR) spectral range. . Compared to NIR spectroscopy, TriEye's SWIR systems offer a significant value proposition, opening the door to next-generation sensing capabilities. This includes resilience to sunlight and other sources of ambient noise, while providing an eye-safe light source. Through this combination, the photoelectric sensing system will have a longer detection range and better detection accuracy than previous near-infrared-based systems.

     The launch comes after TriEye introduced a short-wave infrared sensing system based on SEDAR (Spectrum-Enhanced Detection and Ranging) technology – which is touted as the ultimate sensing system for automotive applications. The system provides rich image data and depth information based on SWIR. From this, SEDAR adds depth data to the sensor's 2D imaging data: the Z-axis, providing machine vision systems with three-dimensional information about the environment.

     Using TriEye's proprietary depth algorithm, SEDAR technology generates a point cloud that is calculated pixel-by-pixel using a pulsed illumination method. The combination of high-definition (HD) depth information and SWIR imagery provides the optimal spatial layout of the environment, informed by real-time dynamic scene optimization. Importantly, due to eye safety concerns, this dual approach can only be applied to the short-wave infrared spectrum, another key advantage, notes TriEye co-founder and CEO Avi Bakal!
