摘要： Multi-spectral methods and systems for the day and night remote sensing (detection, identification, and quantification) of greenhouse gas emission sources from space are provided. The sensor system includes a telescope assembly that passively collects light from an observation area and directs that light through spectral, optical filters and to a sensor array having a plurality of rows and columns of pixels. Different groups of sensor array pixel rows are aligned to receive light that has passed through different optical filters. The filters have passbands corresponding to the reflective and emissive bands of gases of interest, as well as associated reflective and emissive reference bands, and broadband spectral bands. A set of image data frames is obtained as the field of view of the sensor system moves over an observation area and an aggregate image showing locations of detected gas emissions is generated using the collected data.

摘要： A compact perception device for an autonomous driving system is disclosed. The compact perception device includes a lens configured to collect both visible light and near infrared (NIR) light to obtain collected light including collected visible light and collected NIR light. The device further includes a first optical reflector optically coupled to the lens. The first optical reflector is configured to reflect one of the collected visible light or the collected NIR light, and pass the collected light that is not reflected by the first optical reflector. The device further includes an image sensor configured to detect the collected visible light directed by the first optical reflector to form image data; and a depth sensor configured to detect the collected NIR light directed by the first optical reflector to form depth data.

摘要： Infrared (IR) photodetecting systems and methods. A system may comprise at least one photosite having a Ge photosensitive area (GPSA) that includes an absorber doped area having a first polarity and a Si layer comprising a first doped area (FDA), a storage well (SW), a floating diffusion (FD) and a transfer gate (TG); a controllable power source (CPS); and a controller, operable to control the CPS and the TG, to concurrently provide at a first time controlled voltages to the GPSA, FDA and FD, thereby forcing charge carriers of a given polarity (CCGP) from the GPSA toward the SW and to provide at another time other voltages to the GPSA, FDA and FD, thereby diminishing the forcing of the CCGP toward the SW and ceasing collection of signals by the SW, and to intermittently transfer the CCGP from the SW via the TG to the FD, where the CCSP are read via an electrode coupled to the FD.

摘要： A range imaging device includes a light source unit that emits light pulses to a measurement space; a light-receiving unit including a photoelectric conversion element that generates charge according to light incident from the space, a pixel circuit including charge storage units in which the charge is integrated in a frame cycle, and a pixel drive circuit that performs switching operation of transfer transistors to distribute the charge to the storage units for integration at integration timing synchronizing with emission of the pulses; and a distance calculation unit that calculates a distance between object in the space and the light-receiving unit based on charge determined by a first charge integrated in each storage unit. The calculation unit calculates the distance by subtracting a second charge from each first charge, the second charge being noise charge as an integrated charge other than the charge distributed and integrated by the switching operation.
