Latest Patents

One of McCarrick's latest patents is titled "Fiber optic coupled multipass gas minicell, design assembly thereof." This invention involves a method that directs a gas of interest into a minicell. It utilizes an emitting laser to produce laser emission light that is directed into the minicell and onto the gas of interest. The laser emission light is reflected within the cell, allowing for multiple passes through the gas of interest. After these multipasses, the laser light is analyzed to produce gas spectroscopy data. The minicell is designed to receive the gas of interest, with a transmitting optic connected to it that directs a beam into the minicell. A receiving optic then captures the beam from the gas and directs it to an analyzer for data production.

Another notable patent is the "System for uncollimated digital radiography." This invention employs an inversion algorithm based on the maximum entropy method (MEM) to remove unwanted effects in high-energy imaging. The algorithm processes images from a thick scintillator and the radiography setup geometry to output a restored image that mimics one taken with an infinitesimally thin scintillator. This technique can significantly reduce exposure time or required source intensity while minimizing object blurring in images. It is applicable in various radiographic applications, including fast neutron, high-energy gamma, and x-ray radiography.
