Augmented Reality Development Workflow: Lumerical, Zemax, and Speos Integration-Part1
Hello everyone, this is Majid Heidari from Ozen Engineering, Inc. Today, I would like to discuss how we can use ANSYS optics and photonic tools to simulate AR/VR systems. ANSYS provides various tools such as Lumerical, Zemax, and Speos. I will demonstrate how we can utilize these tools effectively.
Overview of AR Glasses
Let's start by looking at a sample of AR glasses. These glasses include:
- LED lights
- A light pipe
- An optical system
- A marked reality display
- In-coupling and out-coupling elements for the eyes
Our goal is to simulate the optical system of these glasses, focusing on the micro LED display and the augmented reality aspects. I have additional videos on simulating micro LED displays, which you can refer to for more information.
Workflow for Augmented Reality
For augmented reality, we need to:
- Design and optimize the optical system.
- Work with diffractive optics elements at different scales, from nanoscale to ray optics scale.
- Consider optomechanical packaging in simulations.
- Conduct stray light analysis and address structural and thermal issues.
- Perform system-level simulations, integrating environmental parameters and visualizations.
Tools and Techniques
ANSYS provides several tools for these tasks:
- Zemax for optical design and ray optics.
- Lumerical for nanoscale simulations, including diffractive optics elements.
- Speos for system validation and photometric and colorimetric measurements.
Nanoscale Simulation with Lumerical
Lumerical's RCWA (Rigorous Coupled-Wave Analysis) is a semi-analytic method used to calculate reflected and transmitted fields from a plane wave incident on a structure. It allows for optimization of parameters such as:
- Pre-yield
- Height
- Angles
System Validation with Speos
Speos enables testing and validation of designs in virtual control scenarios from a human vision perspective. It considers multiple environments, including:
- Interior and exterior settings
- Natural and artificial light
- Daylight and nighttime conditions
Speos includes human vision models that account for eye sensitivity, glare, shadow, and other parameters.
Conclusion
In summary, ANSYS optics and photonics tools provide a comprehensive workflow for simulating and validating AR/VR systems. From nanoscale to system-level analysis, these tools help optimize and validate designs effectively.
Thank you for your attention. Please refer to additional resources and videos for more detailed information on each tool and technique.
Hi everybody, this is Majid Heidari from Moussineq Engineering. Today I would like to discuss how we can use ANSYS optics and photonic tools to simulate AR/VR systems. We have different tools in ANSYS, such as numerical, Zemax, and S-codes. I will show you how we can use these tools.
Let's first look at the workflow of ANSYS. Here is a sample of AR glasses with LED lights, a light pipe, an optical system, a Marked Reality Display, glasses, and in/outcoupling to the eyes.
We want to simulate the optical system on our glasses and vitalize the ITA sharp and the eye access of the android pro sensor on the front side of the two primary tactical Chairman glasses. We also want to start the optical system on them first and consider the micro LED display.
For augmented reality, we have optical design, which we need to design and optimize. Inside the glass, we have some diffractive optics elements that we need to design and optimize. We need to consider optomechanical packaging and stray light analysis.
We also need to figure out the luck ratio and do some system level simulation, considering environmental effects and integrating environmental parameters and visualization. We can use ANSYS optics and photonic tools for all of this work.
For instance, we can use Zemax for optical design, numerical for macro display, and Zemax for stray light and structural thermal analysis. We can do system analysis with SBOS. Let's first focus on the nanoscale. On the nanoscale, we have a great tool named RCWA, which is a part of Lumerical FDTD.
RCWA is a semi-analytic method that can calculate the reflected and transmitted field from a plane wave incident and the structure. We can optimize it by adjusting the pre-yield, height, lengths, and angle.
In the first part of my demo, I will show you how to simulate the diffractive optics element with RCWA. We have RCWA in ANSYS optics and photonics tools, which is good for nanoscale simulation. We can optimize the pre-yield, yield cycle, height, and angle in RCWA.
We can also design the optical system in Zemax and analyze the refractive optics by calling Lumerical as a backend. We can optimize the image quality and validate the system with ESPOS, which can test and validate the design in a virtual control scenario from the human vision perspective.
Let's start with ANSYS Lumerical and have an explanation about how a device starts when you put your hand on it. If it's a native device, whether it's a portable device or tablet, you start filling the device with one hand, move word positions, and close it. Thank you.
