X-ray micro-CT system
We built an innovative x-ray microscope based on a high brightness rotating anode x-ray generator (Rigaku FrE+) able to acquire high resolution micro-CT of biological specimens. The instrument was specifically designed to develop advanced x-ray methods in small laboratories and boost applications in bio-medicine and materials science.
Optical Projection Tomography
We co-developed an optical projection tomography (OPT) instrument with multi-channel fluorescence capabilities and an option for infrared transmission tomography. The instrument features a custom-built tomography stage, a choice of three different objective lenses, and a high resolution CCD camera. The control system environment is written in LabView™ and enables full automatic control of the instrument parameters. The instrument is installed at the Monash Micro Imaging Facility of Monash University, in collaboration with A/Prof Ian Smyth, Dr. Kieran Short and Dr. Robert Bryson-Richardson.
Iterative retrieval algorithms
We developed iterative algorithms to retrieve the length of a picosecond electron bunch from the measurement of its infrared spectrum. Codes were developed in GDL and C++ in collaboration with T. Sen from the Fermi National Laboratories (Fermilab, USA), for real-time use at their accelerator facility. Further details on the algorithm can be found here.
NIR classification of macadamia nuts
We developed a preliminary classification of macadamia kernels by near-infrared (NIR) analysis using the Luminar 5030 by Brimrose Corporation of America. We were able to sort fresh kernels from stale and rancid, as well as distinguish between cultivars. This work shows the potential of applying NIR to grade and sort macadamia.
