The indispensable software to fully reveal DHM possibilities
The koala software is an essential component , that contains most of the innovating concepts of the DHM Technology. In addition to DHM specific functions, koala implements a large variety of standard tools and advanced features for data processing, measurements and external controls, in a flexible and user-friendly environment.
Koala allows different operating modes, providing flexibility to address different situations with the same instrument:
Single wavelength live mode
The acquisition and the digital reconstruction are performed in real-time using a single illumination wavelength. Step heights up to half the wavelength can be resolved.
Dual wavelength live mode
The acquisition and the digital reconstruction are performed in real-time using two simultaneous illumination wavelengths. Step heights up to half of the beating wavelength (several micrometers) can be resolved.
Alternate dual wavelength mode
The measurements are performed by the acquisition of holograms illuminated alternately by one of the two different wavelengths. It allows resolution of step heights up to half of the beating wavelength (several micrometers).
Vertical scanning mode
A coherence scan is performed over the sample height. Heights up to several millimeters can be measured.
Time-averaging mode
Several acquisitions in time are averaged in one measurement for ultimate vertical resolution.
Sequence mode
Allows the recording of a time sequence that can be turned into an .avi file.
Offline reconstruction mode
Allows postponed reconstruction of stored holograms for additional measurements, focus correction, post-treatment...
Stitching mode (optional)
Automatic procedure to attach images side by side in X/Y direction to increase the field of view.
Stroboscopic mode (optional)
Drives the device to be measured (MEMS, MOEMS...) and synchronizes the acquisitions to fully characterize the sample’s movement over its cycle.
Production mode (optional)
Customized interfaces are integrated into the software for specific applications.
