Boston-based Teradar has unveiled its groundbreaking Summit terahertz-band vision sensor at the Consumer Electronics Show (CES) 2026 this week. Following a significant $150 million fundraise just two months prior, the company is positioning Summit as the first long-range, high-resolution sensor of its kind, engineered for exceptional performance in all weather conditions. This innovative technology aims to fill critical performance gaps left by conventional lidar and radar sensors in the rapidly evolving autonomous vehicle market.
The Summit sensor, a solid-state device with no moving parts, leverages the relatively untapped terahertz band of the electromagnetic spectrum, situated between microwaves and infrared. This unique approach is designed to combine the best attributes of both lidar and radar technologies while minimizing their inherent drawbacks, offering a potentially more cost-effective and robust solution for automakers.
Teradar anticipates the Summit sensor will begin shipping by 2028, contingent on securing contracts with major automakers. Successful adoption could enable these manufacturers to integrate advanced partial or even full autonomy features into their vehicles. The company is already collaborating with five leading U.S. and European automakers, alongside three Tier 1 suppliers, to demonstrate its technology.
Teradar's market entry comes at a crucial time for automotive sensor suppliers. The lidar sector, in particular, has faced significant headwinds. U.S. lidar leader Luminar, for instance, filed for bankruptcy protection in December 2025 after key contracts with Volvo and Mercedes-Benz collapsed, reportedly due to automakers scaling back on the technology, as detailed in reports. These deals also crumbled partly because of intense low-cost competition from China.
Despite these challenges, lidar adoption remains strong in the Chinese auto market, with companies like Hesai producing over 1 million lidar sensors in 2025 alone. Other U.S. players, such as Ouster (which merged with rival Velodyne after a wave of consolidation), have diversified their focus into markets like robotics and smart infrastructure to navigate the volatile automotive landscape.
Teradar's ambitions extend beyond the automotive sector, a vision reflected in its recent $150 million Series B funding round. This round saw investment from Lockheed Martin's venture arm and VXI Capital, a new defense-focused fund led by the former CTO of the U.S. military's Defense Innovation Unit.
While the lidar market faces challenges, it's not entirely defunct. Rivian's announcement in December 2025 to integrate a roof-mounted lidar sensor (from an unnamed supplier) into its upcoming R2 SUV indicates a continued appetite for advanced sensor technology in passenger vehicles, especially if it's affordable.
Teradar CEO Matt Carey expressed confidence in his company's ability to meet these market demands. "Our main job is to make sure our sensor gets on all automobiles, and whatever the best way to do that is, that's what we're going to pursue," Carey told TechCrunch in November.
