Example Embodiment

[0032] In the following description, specific details such as specific system structures, techniques such as specific system structures, and techniques are proposed to illustrate the embodiments of the present invention. However, those skilled in the art will appreciate that the present invention can also be implemented in other embodiments without these specific details. Detailed description is omitted of well-known systems, devices, circuits, and methods in other cases so as not to obscure the description with unnecessary detail the present invention.

[0033] In order to illustrate the technical solution of the present application, the following will be described below.

[0034] Lidar is a target detection technology. Laser radar emits the laser beam by a laser, diffuse reflection occurs after the laser beam encounters the target object, the received light beams reflected back by the detector, and determines the target object's distance, azimuth, elevation, and speed in accorda...

Abstract

The invention discloses a trans-impedance amplifier array, a light receiving device and a laser radar receiver, which can be applied to the field of automatic driving or intelligent driving. The light receiving device can comprise the trans-impedance amplifier array and a photoelectric sensor array, the trans-impedance amplifier array and the photoelectric sensor array are arranged in a stacked manner, and the trans-impedance amplifiers and the photoelectric sensors are connected in a one-to-one correspondence manner through the solder balls, so that the integration level of the light receiving device is improved, and the influence on the performance of the laser radar is reduced.

Description

technical field [0001] The present application relates to the technical field of laser radar, in particular to a transimpedance amplifier array, a light receiving device and a laser radar receiver. Background technique [0002] Lidar is a target detection technology widely used in intelligent driving vehicles, intelligent driving aircraft, three-dimensional (3D) printing, virtual reality, augmented reality, service robots and other technical fields. The laser radar emits a laser beam through a laser. The laser beam encounters a target object and undergoes diffuse reflection. The reflected beam is received by the light receiving device, and the distance, orientation, height, and speed of the target object are determined according to the emitted beam and the reflected beam. , posture, shape and other feature quantities. [0003] At present, since the lidar requires an increasingly larger detection area, the transimpedance amplifiers are usually arranged in a single arrangemen...
