HUD: Design and Analysis

HUD imaging systems design and analysis tools
- HUD design and analysis permits users to study the technical feasibility of a HUD according to windshield shape and packaging constraints
- Automatic tools help design the optical system and improve the perceived quality of the image by optimizing layout and shapes, generating a rotation axis, calculating angles for multiple drivers’ sizes, and automatically displaying required optical volume.
- Objectively qualify the image quality and compare several technical options, scoring the optical and vision performance.
- Validate the compliance against your acceptance criteria and create a complete simulation of the driver’s perception.
Simulation result experience

- Speos Live Preview interface allows users to experience real-time simulation results. Powered by GPU-Compute with Nvidia GPUs Speos Live Preview enables users to:
- See the result from the beginning of the simulation, browse results from available sensors, and review light levels in false color or true visual aspects in Human Vision.
- Save results any time to further explore and measure in Photometric Labs.
- Change most optical properties at any time, and with one click, restart the simulation.
Ray tracing and Ray Propagation Engine

Interactive ray tracing and ray propagation
Ray Tracing
- Understand ray behavior instantly and see the impact of modeling change as the ray path updates upon design modification.
- Theoretical regularly sampled ray sources can design lighting concepts and manually guide the rays toward your target.
- Visualize Ray Tracing from any light source to review and adjust your design before running any simulation.
Ray Propagation Engine
- Reciprocity of the direct and inverse propagation modes guarantees the accuracy of results whatever the mode selected.
- Simulations permit the materialization and testing out an optical system by propagating rays through the key components of the optical simulation (materials, sources, sensors).
Advanced analysis tools

- Light Expert offers the possibility to visualize interactions between light and the different geometries of the optical system to identify potential causes of stray light, ghost images, and reflections.
- The stray light analysis capabilities of Speos permit designers to understand the behavior of the rays before they reach a sensor: all paths the light follows as well as the contribution of each sequence.
- Result Layering: The rays integrated by the different sensors can be analyzed by separating the elements contributing to the simulation results.
- The impact of the different sources involved in the propagation, for instance to identify which one contributes to a hot spot.
- The impact of specific faces of the geometries involved during the propagation, optimizes efficiency of the design surface.
- The impact of the different optical sequences followed by the rays during the propagation, identifies stray light causes.
Light Sources

Speos provides different methods to model light sources.
Most LED manufacturers provide measured ray files in the Speos format can define sources, similar to luminaire suppliers with the IESNA LM-63 and Eulumdat files.
- Complex source emission can be considered at the LED chip level, accounting for the surrounding optics during the calculations.
- For physics-based renderings, model ambient sources to add realism to the scene, as well as display sources for car interior simulations.
- Thermal emissivity of different geometries can also be considered for simulations in the infrared full spectral bandwidth.
Lighting Application Optical Design

Light distribution design tools
- Using reflection or refraction properties, Speos offers an easy-to-use interface to design Reflector or Lens with variable grid definition (rectangular, circular, stripes, honeycomb, freeform type).
- Geometrically define each pillow or by set the optical beam spread target with embedded optimization.
- Speos offers the best-in-class lightguide design tool to smoothly control prism parameters variation and ensure efficient and homogeneous light distribution.
- In combination with Speos GPU, users can instantaneously check the photometry of its design by facets or for the whole reflector
Optical Properties

Optical property management
- Volume behavior of materials covers the spectral absorption, scattering, fluorescence, refractive indexes, gradient indexed, and complex refractive indexes, either as models or tabular input.
- Surface behavior description extends from simple Gaussian/specular models to measured spectral 3D BxDFs, anisotropic, retroreflective, iridescent, polarized properties.
- Achieve complex behaviors with spatial variation, multilayer textures with property blending, or dedicated plugins like the LSWM to use optical gratings from Lumerical simulation.
Sensor Integration

- Speos offers dedicated capabilities to simulate and assess camera and lidar raw signals in a driving environment.
- Starting from a digital mock-up, including surrounding geometries, sensor layout and surrounding targets, camera and lidar systems can be physically modeled.
- Integrated into the CAD platform, data acquired by sensor systems can be simulated, considering its characteristics and constraints.
- Complete analyses can be performed for different sensor configurations on various scenarios.
Multiphysics

Ansys product portfolio interoperability
- Speos allows STOP analysis to evaluate the impact of mechanical deformation due to temperature variation on photometric performance.
- Using Workbench integration, Speos and Mechanical connect automatically update the original design with the deformed geometries coming from Mechanical simulation.
Ansys Optics Solutions Interoperability

Speos is part of the Ansys Optics collection, providing interoperability and design workflow solutions with OpticStudio and Lumerical.
- OpticStudio can export optical lens system as a reduced model called Speos Lens System (.optdistortion file) for accurate and fast camera simulation. Please refer to the OpticStudio page to know more about OpticStudio’s capabilities.
- Lumerical simulation grates simulation using SubWavelength Lumerical plugin. Lumerical is also useful in combination with Speos for accurate CMOS simulation. Please refer to Lumerical page to know more about Lumerical’s capabilities.
Optical data exchange

- Speos Light Box permits the export and import geometries along with the associated optical data:
- Sources
- Optical properties (material, surface properties)
- Meshing properties (geometries stored as meshes)
- Light Box can handle data exchange between suppliers and customers. It is compatible with multi-CAD platforms where Ansys software is integrated (SpaceClaim, Speos for NX, Speos for Creo Parametric).
- The file format is encrypted so content cannot be edited outside Speos. Its security can also be reinforced with a password.
