Toward the Super Temporal Resolution Image Sensor with a ...

The theoretical temporal resolution limit tT of a silicon photodiode (Si PD) is ps. We call “super temporal resolution” the temporal resolution that is shorter than that limit. To achieve this resolution, Germanium is selected as a candidate material for the photodiode (Ge PD) for visible light since the absorption coefficient of Ge for the wavelength is several tens of times higher ...

Temporal response of biochemical and biological sensors ...

obtained by the analysis of the temporal response of the sensor. Thus the mathematical models of the sensor response which take into account a larger number of rele-vant effects ensure more reliable information. To analyze the measurement results a simple linear mathematical model of sensor temporal response is com- monly applied (Mehand et al. 2015), in which it is assumed that only ...

Analysis of temporal noise in CMOS photodiode active pixel ...

Active Pixel Sensor Hui Tian, Boyd Fowler, and Abbas El Gamal, Fellow, IEEE Abstract— Temporal noise sets the fundamental limit on image sensor performance, especially under low illumination and in video applications. In a CCD image sensor, temporal noise is primarily due to the photodetector shot noise and the output amplifier thermal and 1 noise. CMOS image sensors suffer from higher noise ...

TEMPORAL RESOLUTION

TEMPORAL RESOLUTION . This lecture considers the topic of Temporal Resolution, which defines the period of time required for a remote sensing platform to revisit a specific geographic location (also known as the revisit period [1]). It is an important factor for detecting changes, and the rate of these changes, occurring on surface of the planet and supports observations of environmental ...

Temporal Filtering - OpenSensorHub

Temporal Filtering. OpenSensorHub's SOS implementation supports both historical and real-time requests for sensor data. Historical requests are automatically enabled (and properly advertised in the capabilities) when a storage is configured and associated to a sensor. Likewise, real-time requests are automatically enabled when a sensor is directly connected to the SOS (and the sensor module is ...
