In the rapidly expanding field of augmented reality (AR), the precise measurement of diffractive gratings used in AR devices is crucial for optimizing their performance and user experience. Therefore, the choice of measurement technique can significantly impact the accuracy and efficiency of the process. While Scanning Electron Microscopes (SEMs) have been a popular choice, Littrow diffractometers are emerging as the superior alternative for evaluating AR diffractive gratings. In this blog post, we will delve into the reasons why Littrow diffractometers should be your go-to choice for assessing the performance of diffractive gratings in AR devices.

How to Use Additional Content in a VR Reference Environment During Temporal Measurements
When testing the Motion-to-photon (MTP) latency of a Head-mounted display (HMD), variables like CPU/GPU load and network bandwidth can affect the result. Therefore, it is quite common that users would like to utilize certain visual content with the HMD during the test, to better match the actual conditions where the device is being used. But there is a fundamental challenge with additional content as the image on the screen is the exact source for the virtual world viewer orientation and location information. And to be able to get that information from an image, certain reference content needs to be viewed.
