Solutions for the automotive industry

What is the significance of cameras in automotive applications for ADAS/AD and DMS/OMS, and how are they evolving?

Cameras play a crucial role in automotive applications with growing importance for active safety-related applications as well as an increase of comfort. The demand for higher image quality and reliable performance continues to grow, driven by the need for more sophisticated image processing. The integration of AI and machine learning cannot replace the need for optimal optical performance to exploit the full capabilities of a camera system’s components. The integrity of the image data provided by cameras is essential for all subsequent processing, whether it occurs at the edge or in central computing. TRIOPTICS supports the entire value chain, from lens testing and manufacturing to active alignment and quality verification of camera modules in production and vehicle integration.

What special technical properties must image processing systems in automobiles fulfill and what challenges still lie ahead?

Image processing systems in automobiles must fulfill several critical technical properties to meet the demands of ADAS and AD. One of the primary challenges is capturing detailed images to improve accuracy in object detection and classification at larger distances or wider fields of view (FOV) which requires higher pixel counts and smaller pixel dimensions. However, this can reduce the depth of field of the lenses, making it more challenging to maintain sharp focus. Advanced calibration methods are required for distortion-free imaging. To address these challenges, TRIOPTICS provides high-precision optical metrology and production solutions. Our advanced alignment and testing systems ensure that cameras are accurately aligned and calibrated to perform reliably in various environmental conditions. By continuously improving our processes, we aim to achieve the highest production speeds while maintaining the required quality standards, ensuring that each camera module meets the stringent performance criteria needed for ADAS and AD systems.

What are the emerging trends in optical sensor technology for driver assistance systems and autonomous vehicles?

The emerging trends are driven by the need for higher levels of autonomy and compliance with legislative requirements. One notable trend is the use of thermal (Long Wave Infrared) cameras, which offer enhanced sensitivity and resolution, making them ideal for detecting heat signatures in various conditions, particularly in low-light and adverse weather. This technology is ready for large-scale deployment and can significantly improve the reliability and safety of ADAS and AD systems. Another significant trend is the adoption of solid-state and frequency-modulated continuous-wave (FMCW) LiDAR. TRIOPTICS has extensive experience in developing solutions for a wide variety of LiDAR systems, combining proven technologies to create effective production solutions from prototyping to mass production. Our customized production and testing equipment ensures that these advanced sensors meet the stringent quality standards required for automotive applications.

Given the advances in sensor technology - what impact does this have on the demands manufacturing is placing on sensor production as they are facing increasingly stringent requirements and handle ever-larger volumes?

We are observing significantly increased demands in production due to advances in sensor technology. The industry's production goals are to produce high-quality sensors efficiently, balancing cycle times and production yields. TRIOPTICS focuses on continuous process improvement to achieve the highest production speeds while maintaining stringent quality standards. When aligning optical sensors, the goal is to find the optimal combination of performance characteristics of the electrical and optical components to meet the quality requirements for the final product. TRIOPTICS' systems are designed to handle these challenges, leveraging data from both the components and the production process to improve yield and throughput. By continuously refining our processes, we aim to optimize cycle times and reduce production costs, making it possible to scale efficiently as the demand for advanced sensors grows.

What challenges is the industry facing and how does TRIOPTICS contribute as a technology leader?

To better leverage the performance characteristics of electrical and optical components in camera production, a deeper understanding of the relationship between camera performance and the quality of its components is required.

TRIOPTICS equipment is regarded in the industry as the benchmark for lens testing, ensuring that a lens’s quality meets specifications and lives up to the quality standards customers expect.
