Vishay / Micro-Measurements PhotoStress Plus Analysis System Description

Functions

Optically measures and analyzes surface strains in components subjected to mechanical loads utilizing photoelastic coatings. Integrates with digital imaging and light sources to visualize stress distribution in real-time. Interfaces with proprietary software for data acquisition, processing, and graphical representation of stress maps. Used in research, development, and validation environments to ensure structural integrity and performance under operational loads. Compatible with a range of coating materials for various substrate applications, facilitating quantitative stress analysis in complex geometries and dynamic load conditions.

Platforms

Optical strain measurement systems designed for integration with digital imaging hardware, equipped with photoelastic coatings and polarizing filters; interfaces with PC-based analysis software for real-time stress analysis in materials; compatible with laboratory and field test setups, connecting via USB or proprietary data acquisition modules; used in mechanical engineering, aerospace, and materials science for stress distribution visualization and quantification on transparent or coated specimens under mechanical loading.

Applications

Utilized for full-field, non-contact photoelastic stress and strain analysis, enabling precise identification of principal stress directions and differences. Applications include design validation, stress concentration detection, residual stress evaluation, and load path analysis in mechanical components, structures, and materials. Critical for fatigue life prediction, failure analysis, and optimization of part geometry in aerospace, automotive, civil, and industrial engineering R&D and quality control.

Accessories

LF/Z-2 Reflection Polariscope with built-in digital video camera, electronic compensator with integral data interface for computer connection, PSCalc software for measurement processing, laser light for principal stress direction indication on test part, complete PhotoStress coating application kit including photoelastic coating and special reflective adhesive. The polariscope interfaces include a connection for the digital video camera output and compensator signal output to computer (likely via standard data cable, specifics not documented). The system is standalone and does not require additional mainframe or backplane chassis.

Interfaces

Requires mainframe chassis for module installation; connectors include USB 2.0 Type-B for data transfer and power, RS-232 serial port 9-pin D-sub female for instrument communication; also features BNC connectors for analog signal input/output and a VGA output (15-pin HD D-sub female) for external display connection.

Specifications

Optical stress analysis system utilizing photoelastic coating technology to measure surface strain distributions through birefringent coating response under polarized light. Integrates high-resolution digital camera, circular polarizer, and white light source with computer-controlled image acquisition and processing software. Quantifies principal stress magnitudes and directions via fringe pattern analysis algorithms, supporting full-field strain mapping with 0.1 fringe order sensitivity. Interfaces via USB/Ethernet for real-time data capture and post-processing. Accommodates various coating thicknesses and calibration constants for different photoelastic materials. Applied in structural testing, fatigue analysis, stress concentration identification, and validation of finite element models in aerospace, automotive, and civil engineering applications.
