Abstract

The invention provides a detection unit, a detection device and a detection method using the detection device. The detection device comprises a light source operable to emit light to illuminate a detected object, a light sensing module which can output an electric signal through a first circuit receiving a first modulation signal and a second circuit receiving a second modulation signal, and a processing module which can receive different control signals for control, so that the detection system can work in different modes, and the two circuits can respectively output electric signals corresponding to phase delay of one of the delay phase receiving control signals, so that the accuracy of detection information is realized, and the detection precision is improved; and meanwhile, the system can reasonably arrange phase delay information and exposure time information in sub-frames in a certain frame frequency mode, so that the high efficiency of the whole system is ensured.

Description

technical field [0001] The present application relates to the field of detection technology, in particular to a detection unit, a detection device and a method. Background technique [0002] In the field of detection technology, more and more technologies are continuously introduced. In order to ensure the efficient and fast detection of targets in application fields such as image or ranging, more and more devices are designed to include multiple taps (two or more than two ) structure, which can work in divided periods to read the photogenerated electrons generated in the pixel unit connected to it. When the multi-tap is arranged reasonably, it can realize the efficient work in the chip or the receiving part formed by it. There are deviations in the signal due to various factors. Even for the photogenerated electrons generated by the same return light incidence, there are differences in the output values ​​of different taps. This phenomenon will have an important impact on i...
