Measurement Logic

How FZT-2 Evaluates Distortion Features

FZT-2 identifies wave-line features within the zebra pattern and applies a consistent method for optical-distortion measurement.

Zebra pattern
Detected wave lines
Feature evaluation
Zebra angle
01

Automatic Feature Detection

Relevant wave-line features are identified automatically within the zebra pattern.

02

Consistent Evaluation

Detected features are evaluated using the same measurement method across samples.

03

Zebra-Angle Determination

The zebra angle is determined when the detected distortion feature reaches the defined evaluation criterion.

System Architecture

An integrated measurement system composed of optical, mechanical and software modules, working together to support stable, accurate and repeatable measurement.

FZT-2 zebra board
01

Zebra Board

Provides a stable, high-contrast zebra pattern for angle measurement.

FZT-2 CCD image acquisition unit
02

CCD Image Acquisition

Captures zebra-pattern deformation through the glass sample using a dedicated CCD camera system.

FZT-2 analysis software
03

Analysis Software

Processes the captured image, identifies stripe deformation and automatically calculates the quantitative zebra-angle result.

FZT-2 mechanical positioning system
04

Mechanical Positioning

Controls sample positioning and measurement geometry to support consistent, repeatable testing.

Quality Control Value

From Visual Evaluation to Repeatable Quality Control

  1. 01

    Reduced Operator Dependency

    Replace subjective visual judgement with a consistent automated measurement process.

  2. 02

    Repeatable Measurement

    Apply the same measurement method across samples and production periods.

  3. 03

    Traceable QC Records

    Retain measurement results for review, comparison and quality investigation.

System Integration

Automatic Reporting

Every Measurement Becomes a Searchable Test Record

The FZT-2 automatically generates a test report after each measurement. Reports are stored locally on the industrial PC and named using the exact test date and time.

  • Quantitative zebra angle result
  • Sample data, deformation curves and detected wave-line positions
  • Time-based file naming for historical traceability
  • Storage for up to two years, depending on configured capacity

Software & Data Output

Software Configured Around Your QC Workflow

FZT-2 can be configured around project-specific measurement, reporting and data-handling requirements.

01

Configurable Measurement Regions

Inspection regions can be defined according to project requirements, including edge, central or other specified areas.

02

Structured JSON Output

Measurement results can be generated as structured JSON files for customer-side review, storage and downstream data handling.

Agreed output fields · Timestamp-based naming · Agreed storage location

03

Measurement Metadata

Records can include agreed information such as sampling time, measurement time and other project-defined metadata.

04

Integration Requirements

Plant and data-system interface requirements can be reviewed during project definition.

MQTT or OPC UA options can be evaluated on a project basis.

Measurement Evidence

From Optical Capture to Documented Result

FZT-2 combines physical zebra-pattern capture, software-based analysis and structured reporting within a defined measurement workflow.
