Abstract

The invention discloses an array type detector, which is characterized by comprising a detection module arranged in an array type, the detection module comprises: M*N pixel units, wherein M and N are integers greater than 2, and each pixel comprises a photodiode unit which is used for acquiring a return light signal and converting the return light signal into photo-generated charge; transfer elements, which are used for transferring the photo-generated charges generated in the photodiode; and a charge storage unit, which is used for receiving the photo-generated charge transferred by the transfer element; at least part of the pixel units share at least part of the transfer elements, and by sharing at least part of the transfer elements, the area occupied when the transfer elements are not shared originally can be reduced.

Description

technical field [0001] The present application relates to the field of detection technology, in particular to an array type detector and a detection system using the same. Background technique [0002] Time-of-Flight (TOF) technology was developed as a method of measuring distances to objects in a scene. This TOF technology can be applied in various fields, such as the automotive industry, man-machine interface, games, robotics and security, etc. Generally speaking, TOF technology works by illuminating a scene with modulated light from a light source and observing the reflected light reflected by objects in the scene. In the existing detection system, in order to ensure that the detection process can obtain higher detection efficiency and also ensure that the detection system has a wider field of view, an array type receiving module is currently used more, and the array type receiving module can have There are tens of thousands of pixel units, and each pixel unit can be a ...
