Abstract

In this paper, we propose a highly sensitive laser spectroscopic imaging method without scanning process. We have investigated analog signal processing circuits, which are supposed to be installed to each pixel of a CMOS image sensor. In the imaging method, modulated signal is extracted from background before signal digitization. It gives wider dynamic range compared to conventional image sensors, including our former report [1]. The imaging time is also much shorter than scanning imaging methods [2]. We designed the circuits for photothermal spectroscopy as an example of application, where the high background signal must be removed for highly-sensitive detection.
