Introduction

Chris Lesiak is an accomplished inventor based in Lincoln, NE (US). He has made significant contributions to the field of imaging technology, holding a total of four patents. His work focuses on enhancing the accuracy and efficiency of imaging systems, particularly in the realm of chemiluminescence and fluorescence.

Latest Patents

One of his latest patents is the Chemiluminescence Compact Imaging Scanner. This invention discloses systems, devices, and methods for accurately imaging chemiluminescence and other forms of luminescence. The compact, flat-bed scanner features a light-tight enclosure, one or more detector bars utilizing linear charge-coupled device (CCD) or complementary metal oxide semiconductor (CMOS) imaging chips, and high working numerical aperture (NA) optics. The scanner operates by scanning closely over a sample in one direction and then reversing direction. It averages intensity readings for each pixel location to compensate for luminescence that varies over time. Additionally, on-chip pixel binning and multiple clock frequencies are employed to maximize the signal-to-noise ratio in a CCD-based scanner.

Another notable patent is the Fluorescence Imaging Autofocus Systems and Methods. This invention involves quantitative fluorescence imaging systems that utilize angular illumination to obtain automatic focus information. The technology employs laser scanning, either point or line scanning, in combination with an area imaging sensor, such as a bi-telcentric scanner. This method determines the sample height relative to a detection axis and corrects for sample height in subsequent scans.
