Latest Patents

Franzen's recent patents showcase his commitment to innovation and practical solutions for complex imaging problems. One of his latest inventions is the Chemiluminescence Compact Imaging Scanner. This ingenious device features a light-tight enclosure that houses one or more detector bars, utilizing linear charge-coupled device (CCD) or complementary metal oxide semiconductor (CMOS) imaging chips. The scanner operates by passing closely over a sample in two opposite directions, which allows for the averaging of intensity readings to compensate for luminescence that varies over time. Additionally, it employs on-chip pixel binning and multiple clock frequencies to enhance the signal-to-noise ratio, demonstrating a sophisticated approach to imaging.

Another notable patent involves the development of systems and methods for extending the dynamic range in imaging systems, particularly in fluorescence or luminescence imaging applications. In this invention, images of a sample are captured at various exposure times, where a system-level dark estimate is subtracted from each image to create dark-corrected images. These are subsequently merged on a pixel-by-pixel basis, resulting in a wider dynamic-range image that addresses key challenges in low optical background imaging.
