A system for providing an improved image of daytime and nighttime scene for a viewer within a vehicle is provided herein. The system includes: a pixel array sensor having a fully masked gate-off capability at a single pixel level, wherein the pixel array sensor is provided with an inherent anti-blooming capability at the single pixel level; wherein each pixel is gated by a corresponding transfer gate transistor having high transfer gate efficiency. The system further includes a gating unit configured to control the transfer gate transistors with pulsed or continuous wave modulated active and passive light sources, to yield a synchronized sensing signal from the sensor, wherein a single pulse is sufficient to cover the entire field of view of the sensor and the entire depth of field of the illuminated scene; and a processing unit configured to receive the synchronized sensing signal and process it.

A solid-state imaging device includes an N-type semiconductor layer, an element layer including a photoelectric conversion element and an active element, an interconnect layer providing an interconnect for the active element, and an element isolation trench penetrating the semiconductor layer. The element layer includes a P-type region and an N-type region. A first hole storage layer is formed on a surface of the semiconductor layer on a side opposite to the element layer. A second hole storage layer is formed in contact portions of the semiconductor layer and the element layer with the element isolation trench. The P-type region of the element layer and the first hole storage layer are connected to each other by the second hole storage layer.

A NIR spectrometry device that includes different NIR PIN diodes (NPDs) and a guard PIN diode (VLPD) that are operated in a fully depletion mode. The different NPDs are located at different lateral positions corresponding to absorption depths of different NIR wavelengths. Each NPD is configured to collect electron-hole pairs (EHPs) generated by radiation that passes through a side edge of the device at a wavelength having an absorption depth that corresponds to a lateral position of the NPD. The VLPD is located at a lateral position that corresponds to a distance from the side edge that exceeds an absorption depth of visible light. The VLPD is configured to collect EHPs generated by unwanted radiation that passed through the side edge of the NIR spectrometry device and to prevent the EHPs generated by unwanted radiation to reach any of the different NPDs.
