Ultra-Precision Manufacturing Lab

Ultra-Precision Turning

Many technical applications are only made possible through the use of ultra-precise components, especially with the functionality, ease of use or accuracy we are accustomed to. Examples of this are GPS navigation or high-resolution cameras on cell phones, ultra-fast data connections using fiber optics and mobile phone networks, micro-fluidic sensors in medical technology or ever more powerful computer chips. This article presents the technology used for this, ultra-precision manufacturing, which includes both the machines and tools used. The process parameters to be observed are also discussed. The focus of this White Paper is on ultra-precision turning, although many of the considerations can also be applied to other ultra-precision manufacturing processes like milling.

Mixed Reality Head-Mounted Displays — A Comparison of Tracking Accuracy in Large Scenes

Unlike traditional virtual reality head-mounted displays (HMDs), which confine users to a small tracking area and rely on external sensors, modern mixed reality (MR) HMDs can track user movements across larger spaces without external markers. This paper reviews several MR-HMDs currently on the market and evaluates the tracking accuracy and loop closure capabilities of four commercially available models across four distinct scenarios. Notably, HMDs with video see-through capabilities exhibit varying levels of visual degradation. Results from tracking experiments indicate that all devices perform consistently well in expansive, well-lit environments, with tracking accuracy remaining stable even in outdoor nighttime conditions. Additionally, most HMDs demonstrated effective error correction during loop closure, with errors in non-loop scenarios consistently exceeding those in loop scenarios.

Digital Twins- Classification and Examples

Diverse technical applications utilize digital twins. However, the term “digital twin” encompasses a wide spectrum of meanings, often lacking clarity regarding its specific attributes, and what parts of the real system it represents. This Whitepaper proposes a classification of digital twins based on two criteria: the type of communication between the digital twin and reality, and the simulation speed at which the digital twin mirrors reality. This classification is supported by numerous practical examples illustrating the classification.

Optical Coating and Characterization Lab

Atomic Layer Deposition at RhySearch

Atomic Layer Deposition (ALD) is a well-established coating technique in the semiconductor industry and is now becoming an increasingly attractive option in the field of optics for coating of components with complex geometries. In this Whitepaper we outline some fundamentals of ALD and the benefits and challenges it offers for optical designs. In addition we describe the deposition system and ALD process development at RhySearch.
