Embodiment Construction

[0032] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0033] In order to illustrate the technical solution of the present application, specific examples are used below to illustrate.

[0034] LiDAR is an object detection technology. The laser radar emits a laser beam through a laser. The laser beam encounters a target object and undergoes diffuse reflection. The detector receives the reflected beam and determines the distance, orientation, height, s...

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...
