Diffract Technologies

Quantitative high resolution 3D capture for AR/VR, engineering, and telemedicine.

Variable phase contrast visible light microscope for holographic X-ray detection.
Holographic X-ray Detection

I invented an X-ray detector, using techniques from the field of holography, with an order of magnitude improvement in resolution (208 lp/mm) and an order of magnitude improvement in quantum efficiency (> 80%) at 40 keV. This technology has vast implications for building X-ray imaging systems with higher resolution and lower radiation dose. Publication pending.

X-ray Differential Phase Contrast Microscopy

X-ray DPC is a tool for measuring the extend to which X-rays are bent by the objects that they pass through. This provides additional information about the composition of the object.

Holographic Fiducial Marks

Holoraphic fiducial marks enable precise alignment of objects in all 6 degrees of freedom. This work has been published in Applied Physics Letters.

iLabs - Remote Experimentation

iLabs is a remote experimentation platform that I build with Professor Lambertus Hesselink and Lars Neustock. It records a physical experiment as a state machine so multiple remote students can conduct a virtualized experiment.

Microcosmos

Microcosmos is an online microscopy community for foldscope users. The community includes over 7,000 users and totals more than 15,000 posts on microscopy.

10,000 Microscopes

I worked with Professor Manu Prakash, Dr. Jim Cibulski, and Dr. Laurel Kroo to distribute 20,000 Foldscopes ($1 microscopes) to 10,000 different users in 130 different countries. (News of the project)
