Embodiment Construction

[0053] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0054] In the field of laser detection technology, the detection is carried out by the laser beam emitted by the laser transmitter. Among them, the greater the peak power of the laser transmitter, the longer the detection distance of the laser beam emitted by the laser transmitter, which makes the application scenarios of the laser detection technology more abundant. Therefore, how to increase the peak power of the laser transmitter has become an urgent problem to be solved.

[0055] The embodiment of the present application provides a laser emitter, see figure 1 , the laser transmitter includes: a printed circuit board 1, at least one laser chip 2, at least one capacitor 3 and at least one transistor 4 positioned on the printed...

Description

technical field [0001] The present application relates to the technical field of laser detection, in particular to a laser emitter, a laser radar and a method for determining feature information. Background technique [0002] In the field of laser detection technology, the detection is carried out by the laser beam emitted by the laser transmitter. Among them, the greater the peak power of the laser transmitter, the longer the detection distance of the laser beam emitted by the laser transmitter, which makes the application scenarios of the laser detection technology more abundant. Therefore, how to increase the peak power of the laser transmitter has become an urgent problem to be solved. [0003] In the related art, a single laser tube is mounted on a printed circuit board, and multiple printed circuit boards are combined to obtain a laser emitter, so as to increase the peak power of the laser emitter. However, the laser emitter obtained by combining multiple printed cir...
