Introduction
Morpheus™ is a data processing software package that enables you to analyze and process metrology data from a test optic (the “unit under test” or UUT) measured using a computer-generated hologram (CGH) provided by Arizona Optical Metrology (AOM). Morpheus™ provides a simple interface to quickly ensure your data is processed to provide accurate results.
Morpheus provides the following processing steps:
- Align and remove the CGH substrate error
- Correct mapping relations between the unit under test (UUT) and the CGH
- Detect and optionally remove misalignment modes in the measurement
After the above steps are completed, you can create a report summarizing the metrology results, and export the processed measurement data for further analysis in other software packages.
This user manual is organized in order of the processing steps that can be performed on the data.
Installation
