Optical sensors and systems

|
> Absolute distance between the sensor
and a surface, from a few tenth of microns to more than 10 meters.
> Positioning, real time deformation measurement, level measurement
(molten glass or metal).
Example:
- Measurement of the level of molten glass at 1600°C
- Positioning of a telescope mirror
??œ
> From 10 microns to several
hundreds of millimeters.
> Translucent materials: direct or indAirect measurement (a patented
method particularly efficient for in-line measurements).
> Thickness measurement of flat products using an optical fork sensor.
Example:
- In-line control of television screens
- Thickness control of watch glasses during the polishing operation
- Real time control of quartz or silicon wafers during the etching process. | Localisation of interfaces |
> Positioning of elements along the
measurement axis.
> Localisation of interfaces in guided optics.
Example:
- Control of the position of lenses in precision optical systems. | Analysis of internal structure of diffusing materials (tomography) |
> Composite materials
> Biological tissues
