Embodiment 1
[0043] This embodiment provides a debugging device for a laser beam expander of a sequencer. The debugging device is used to measure the uniformity of the laser instead of the naked eye, and calculate the angle value to be adjusted, so as to realize accurate and efficient adjustment.
[0044] Such as figure 1 and figure 2 As shown, the debugging device of this embodiment mainly includes a laser power sensor 1 , a processor 2 and a display 3 .
[0045] There are several laser power sensors 1 , and eight are taken as an example for illustration in this embodiment. Eight laser power sensors 1 are arranged on the optical path of laser beam emitted by the laser beam expander 4 of the sequencer, and the eight laser power sensors 1 are arranged on a straight line at equal intervals, and the straight line where the eight laser power sensors 1 are located is aligned with the optical axis of the laser vertical, so that the eight laser power sensors 1 can simultaneously detect the lig...
Embodiment 2
[0056] This embodiment provides a debugging device for a laser beam expander of a sequencer. The debugging device mainly includes a light intensity value detection device. The light intensity value detection device is a detection device in the prior art. For example, the light intensity value detection device is a photometric instrument.
[0057] The light intensity value detection device includes a detection module, a processing module and a display module, and the processing module is connected to the detection module and the display module with signals respectively.
[0058] The detection module is an optical sensor, which is used to move to several positions on the same focal plane where the laser beam expander emits laser light, so as to obtain illumination at different positions on the same focal plane of the laser, generate corresponding laser light intensity signals, and The signal is sent to the processing module.
[0059] The processing module can calculate the lase...
Embodiment 3
[0064] This embodiment provides a debugging method for a laser beam expander of a sequencer, which is implemented based on the debugging device in the first embodiment above.
[0065] like Figure 6 As shown, the debugging method of this embodiment includes the following steps:
[0066] S01: Detect the laser light intensity value;
[0067] The laser beam expander 4 of the sequencer emits expanded laser light, and the laser light is respectively irradiated on eight laser power sensors 1 arranged vertically to the optical axis.
[0068] The eight laser power sensors 1 obtain laser irradiation respectively, generate corresponding laser light intensity signals, and transmit the light intensity signals to the processor 2 .
[0069] In order to calculate the adjustment angle value more accurately, the laser beam expander 4 of the sequencer irradiates multiple times, and the laser power sensor 1 will generate multiple laser light intensity signals. Each irradiation will generate 8 ...
