Title: Mao Nakajima: Innovator in Photon Counting Technology
Introduction
Mao Nakajima is a prominent inventor based in Hamamatsu, Japan. She has made significant contributions to the field of photon counting technology, holding a total of six patents. Her work focuses on developing advanced devices that enhance the accuracy and efficiency of photon detection.
Latest Patents
Among her latest innovations are two notable patents related to photon counting devices and methods. The first patent describes a photon counting device that includes multiple pixels, each equipped with a photoelectric conversion element. This element converts input light into charge, which is then amplified and converted into voltage by an amplifier. An A/D converter transforms the voltage output from the amplifier into a digital value. A correction unit is included to adjust the digital value, minimizing the impact of variations in gain and offset values across the pixels. The calculation unit sums the corrected digital values from at least two pixels, while a conversion unit translates this summed value into a number of photons.
The second patent also focuses on a photon counting device, featuring a similar structure with multiple pixels. Each pixel contains a photoelectric conversion element, an amplifier, and an A/D converter. The conversion unit in this patent refers to reference data to convert the digital value output from the A/D converter into the number of photons, based on the gain and offset values for each pixel.
