Powerful API in OpticStudio Used to Simulate X-ray Interforometers

Powerful API in OpticStudio Used to Simulate X-ray Interforometers

Currently, x-ray imaging has fairly poor resolution.  The systems must image large areas, such as a patient’s ribcage or a traveler’s suitcase, so the detector pixels are large.  The x-rays interact weakly with many materials, too, making it difficult to distinguish between, for example, liquids and powders. 

Jeff Wilde and Lamertus Hesslink at Stanford University have shown that a simple Talbot-Lau x-ray interferometer can be used to achieve much higher image resolutions, without improving either the source or the detector of the system.  In addition, they can analyze the contrast of the fringes to create “dark field” images that can distinguish between materials that scatter the x-rays in different ways.

OpticStudio TrueFreeform Optimization for Complex Illumination Systems

OpticStudio TrueFreeform Optimization for Complex Illumination Systems

In recent years, there is a growing need for lighting equipment that creates complex, specific illumination, and light intensity distributions, such as road surface drawing lamps, aesthetic design lighting, and direct backlighting. When designing such lighting equipment, we may often have to use a cut-off method, which is a method of projecting a partially shaded image.

Leveraging OpticStudio in the Construction of UV-C Mask Decontamination Chambers

Leveraging OpticStudio in the Construction of UV-C Mask Decontamination Chambers

In the last blogpost, we featured a study conducted by Stanford University Photonics Research Center to analyze the performance of two different decontamination chamber geometries for mask sterilization.  With the alarming number of COVID-19 cases escalating around the world, finding a solution to meet the growing demand for personal protective equipment (PPE) for hospital staff serving on the frontlines is critical.  With a shortage of PPE worldwide, many medical facilities are forced to decontaminate and re-use their supply of N-95 masks. Optics plays a role specifically as UV-C lighting is used inside of appropriately configured decontamination chambers to provide the necessary sterilization.
