A 190–1100nm waveband multispectral imaging system is presented utilizing a high light resistance, wide dynamic range CMOS image sensor. The specially developed prototype image sensor exhibited 190–1100nm spectral sensitivity, 94dB wide dynamic range with 87ke− full well capacity and 1200fps frame rate, and no degradation of light sensitivity and dark current was observed after strong UV-light irradiation...
An ultraviolet (UV) sensor is demonstrated with high sensitivity in the UV waveband and low sensitivity in the visible (VIS) and near-infrared (NIR) wavebands, utilizing only bulk silicon technology. The developed sensor utilizes the differential spectral response of photodiodes (PDs) with a high UV sensitivity (PD1) and a low UV sensitivity (PD2), for UV signal extraction under a VIS and NIR light...
