Small size and weight: compact and rugged.
- Fast cycle time: typical write/erase cycle less than 10 seconds.
- Can produce high resolution holograms with very little illumination.
- Write/erase thousands of times on each film plate.
Very wide dynamic range.
- All processes automatically controlled.
- Dimensionally stable.
Residual Stress Analysis
The hologram is electronically recorded on a very stable specially prepared glass plate.
The real-time image of the object can be superimposed on the hologram and will show any mechanical movement of the object surface.
The movement of the object is seen as interference fringes. The hologram, object, and fringes can be displayed on a video monitor. The object with it's interference patterns can be recorded from the video monitor as a single image for computer processing, or on video tape in the case of varying deflection.
EXTREMELY ACCURATE: Detects and displays movements of less than 30 nm.
EASY ACCESS: A variety of effects can be studied : thermal, chemical, mechanical, etc. The object under study can be drilled, heated, cooled while mounted in place to permit real-time holographic analysis.
SAFE: Can use low power (7mW HeNe laser).
VERY FLEXIBLE: All holograms can be made in normal ambient light. A variety of illumination angles are easily set by moving the object.
SPECIAL FEATURES: No mechanical, electrical, and thermal interference with measuring environment. Complete immunity to electromagnetic interference.Remote and computer controlled.
