Optical Array Shadow Imaging Software

PROVIDING SCIENTIST/AUTHOR(s): Dr Jonathan Crosier

Optical Array Shadow Imaging Software (OASIS) is a graphical interface for processing raw data files from various two-dimensional Optical Array Probes (OAPs). The software is written for the IGOR Pro software environment. The software reads in raw input from various OAPs, including CIP and CIP-G probes from Droplet Measurement Technologies Inc., and 2D-S and HVPS3 probes from SPEC Inc.

OASIS provides three primary functions:

(1) Convert proprietary raw input files into a commonly formatted hdf5 file

(2) Output filtered particle imagery into a viewable format (PDF, JPG etc).

(3) Create derived data products by mining data from the formatted hdf5 files

OASIS incorporates the following features:

  • Native multithread support, to increase productivity
  • Bath processing tools to support users with large datasets
  • Data export tools
  • Image export tools
  • Particle filtering tools
  • Calculation of various derived data products

Requirements:

Igor Pro Version 6.2 or greater.

Windows XP/7/8/8.1
