Optical & Visibility Testing

Optical performance under icing conditions is critical for systems that rely on visibility, transparency, or signal transmission.

We perform experimental testing of optical components and transparent surfaces to evaluate how icing affects visibility and system functionality.

Why Optical Testing Matters

Ice formation on transparent surfaces can rapidly degrade visibility and system performance.

Even thin ice layers or frost can lead to:

  • Reduced transparency
  • Light scattering and distortion
  • Loss of contrast and visibility
  • Impaired sensor or camera performance

Understanding these effects is essential for designing systems that remain functional under icing conditions.

Testing Approach

We investigate optical performance under controlled icing conditions using both qualitative and quantitative methods.

This includes:

  • Formation of ice and frost on transparent surfaces
  • Observation of visibility degradation over time
  • Evaluation of ice protection strategies

Testing can be performed on flat samples as well as application-relevant geometries.

Measurement & Evaluation

Optical performance is evaluated through:

  • Visual assessment of transparency and visibility
  • Imaging-based analysis of optical degradation
  • Comparison of different system configurations and operating conditions

This allows identification of critical thresholds where visibility becomes impaired.

Ice Protection & System Performance

We evaluate how ice protection systems influence optical performance.

This includes:

  • Required heating power to maintain visibility
  • Effectiveness of de-icing and anti-icing strategies
  • Trade-offs between energy consumption and optical clarity

In many cases, system requirements are defined by visibility thresholds rather than complete ice removal.

Applications

Optical and visibility testing supports:

  • Development of transparent components exposed to icing
  • Evaluation of ice protection systems for optical surfaces
  • Determination of required system performance to maintain visibility

Relevant Industries

Optical testing under icing conditions is relevant for:

  • Aerospace and aviation
    (e.g. cockpit windshields, optical sensors, camera systems)
  • Sensor and imaging systems
    (e.g. vision-based systems operating in cold environments)
  • Automotive and mobility
    (e.g. cameras, LiDAR, and sensor systems)
  • Any system relying on optical clarity in harsh environments
