The Turkish Patent and Trademark Office decided to patent a new surface-scanning method that produces wide and dynamic time spacing between images in microscopic imaging, invented by Assoc. Prof. Serhat TOZBURUN at IBG.
The term "dynamic range" is defined as the ratio between the largest and smallest quantities, especially in engineering. The dynamic range of an imaging system is determined by its ability to decode and measure the minimum and maximum data over time. For example, in photography, long and short exposures, i.e., images with different exposure times, can be combined to produce an image with a wide dynamic range. This technique can, also, be named as wide dynamic range photography via multiple exposures.
The temporal difference between images produced by traditional surface scanning strategies used in imaging techniques, such as laser scanning confocal microscopy, is constant. Therefore, the dynamic range is very narrow, and it is impossible to measure fast or slow changes in one go. The new system and method developed at IBG by group leader of the Biophotonics and Optical Imaging Lab. Assoc. Prof. Serhat TOZBURUN and registered by the Turkish Patent and Trademark Office offers a system and method that proposes a solution to this challenge. The patent reveals that the scanning mirror system, driven by altered/modulated electrical waves, can produce images with a wide dynamic range.
The proposed system and method have many applications, from clinical imaging such as Optical Phase Tomography (OCT) to basic science imaging such as laser scanning confocal microscopy. It is also evaluated to support the technological development needed in laser angiography and Doppler imaging.
