LIDAR sensor system including a dual-polarization transmit and receive optical antenna
A light detection and ranging (LIDAR) sensor system includes a dual-polarization optical antenna, a single-polarization optical antenna, a first receiver, and a second receiver. The dual-polarization optical antenna is configured to (i) emit a transmit beam with a first polarization orientation and (ii) and detect a return beam having a second polarization orientation. The single-polarization optical antenna is configured to detect the return beam having the second polarization orientation.
Total station or theodolite having scanning functionality and settable receiving ranges of the receiver
A total station or a theodolite includes scanning functionality for optical surveying of an environment, in which the total station or the theodolite is configured such that direction-dependent active acquisition regions of the receiver are defined depending on the transmission direction of the transmitted radiation to adapt the receiver surface mechanically and/or electronically to a varying imaging position of the received radiation on the overall detector surface.

Controlling detection time in photodetectors
Example embodiments relate to controlling detection time in photodetectors. An example embodiment includes a device. The device includes a substrate. The device also includes a photodetector coupled to the substrate. The photodetector is arranged to detect light emitted from a light source that irradiates a top surface of the device. A depth of the substrate is at most 100 times a diffusion length of a minority carrier within the substrate so as to mitigate dark current arising from minority carriers photoexcited in the substrate based on the light emitted from the light source.
SOLID STATE IMAGING DEVICE AND ELECTRONIC DEVICE
The present disclosure relates to a solid state imaging device and an electronic device from which a holding unit for holding information in a pixel can be eliminated. When a charge distribution unit distributes a pixel signal SIG to a first ADC, a pixel signal representing only reflection light is divided for allocation. When the charge distribution unit distributes a pixel signal SIG to a second ADC, a pixel signal representing background light and reflection light (partial) is divided for allocation. When the charge distribution unit distributes a pixel signal SIG to a third ADC, a pixel signal representing background light and reflection light (the rest) is divided for allocation. During a period in which no signal is acquired, a discharge transistor functions as an overflow portion for releasing electrical charge. The present disclosure can be applied to, for example, a solid state imaging device used for an imaging device.
