3. For who ?
For what ?
 For car manufacturers and windshield manufacturers
Optical regulation tests
For car and windscreen manufacturers
 12 specific features including view through feature
Allows to simulate manufacturing process effects
The Windshield Analysis has been developed in 2004 for Car Manufacturers working on style, body, life on board, safety as well as Windshield Manufacturers…
Test of the compliance with the regulation ECE R43, SAE Z26
Quantitative analysis of the windshield (distortion, transmission, …)
Qualitative evaluation of the windshield (both in static and dynamic condition)

4. TOOL 1 - Optical Regulation Tests
First, you will master optical behavior of your windshield
TOOL 1 - Optical Regulation Tests
Optical deviation
Optical distortion
Secondary image
separation
Light transmission
Color identification
We can obtain results of all these aspects, to check the optical performance of our windshield. And especially if it complies with the standard (see the Passed and Failed results, automatically calculated.)

5. TOOL 2 - Static distortion visualization
Next step : simulate distortion of your windshield
TOOL 2 - Static distortion visualization
Sighting target in reflection
Sighting target in transmission
Sighting marks
Image distortion
(road, landscape …)
Moiré
When the vehicle is static, these are issues that interest the windshield designer. Moiré is the effect created in the top picture- you see the circles radiating out from the bottom left corner of the windshield? And yet this is just an optical effect caused by two grids overlapping, but one slightly turned. Up until now designers have only been able to predict the Moiré effect by actually constructing a physical prototype, adding grids and a projector.

6. TOOL 3 - Dynamic distortion visualization
And you will be able to do a dynamic simulation as well
TOOL 3 - Dynamic distortion visualization
Processing of initial video by adding distortion produced by the windshield
Initial video
Video with distortion produced by the windshield
SPEOS CAA V5 Based
Windshield Analysis Feature
Windshield geometry
SPEOS can also simulate the windshield’s dynamic state, that is to say when the vehicle is moving. Now we can model exactly how the scenery will look through the windshield. If the scenery is distorted the windshield design needs to be re-worked !
