DTI
Description
This digital phase-shifting
interferometer is developed for cost-effective OEM
solutions. It has a compact size and operates with a
single supply voltage. Ideal for space and power
limited applications, can measure plane, spherical and some
aspheric surfaces. The image sensor is
synchronized with phase shifting element to minimize
acquisition time. Interferometer works with external
coherent laser source, connected via fiber coupler. It
makes possibility to use laser with desired
wavelength and stability. For control and image
capture Fast Ethernet interface is used. Integrated
HTTP server provides simple tuning and testing,
works with all popular Web browsers. Additional
expansion serial interface allows to connect auxiliary
devices (X-Y or rotation tables, attenuators, zoom
objectives, etc.) to create full automatic system.
Features

Software
Library
Open-source, platform
independent, socket based image capture and control library.
Can be used with most popular programming languages (C, C#, Python, Matlab, etc.).
Free Analysis Software
The interferogram analysis
software uses
Python script language. It extends Python
with C control and mathematical modules,
provides fast image capture and short OPD
calculation time. Scripts are very flexible
and designed for easy integration into a
labour or workshop automatic optical
measuring systems.
Free GUI
In additional Free Qt4 based
Graphical
User Interface for Windows and Linux is
provided. It can be used together with
Python interferogram analysis software to
control interferometer, start measurements
and represent results in a graphical form.
