Embodiment 1
[0044] see figure 1 and figure 2 , an illuminating device for a biological tissue online three-dimensional imaging system, comprising a light source and a mounting frame 1; the light source is arranged on the mounting frame 1;
[0045] A plurality of light-emitting points 2 arranged in a circular array are arranged on the mounting frame 1 or around the mounting frame 1; Both are covered with the same point as the monitoring point directly below the center of the annular array of several light-emitting points.
[0046] In order to achieve better illumination intensity, on the basis of the above solution, the central axis of the light beam irradiated by the light source at each light-emitting point passes through the monitoring point.
[0047]In the biological tissue online three-dimensional imaging system, the point where each beam of light passes is the monitoring point where the sample to be detected is placed, and the monitoring point is located directly above the image s...
Embodiment 2
[0063] see Figure 12 , the difference from Embodiment 1 is that the light source includes a driving assembly, a rotating bracket 8 and an LED lamp 9 or a laser light fixed on the rotating bracket; the rotating bracket 8 is connected to the output end of the driving assembly; the light-emitting point It is arranged around the rotating bracket 8. When the rotating bracket rotates, the LED light 9 or the laser light passes through the light-emitting point in sequence and emits a light beam 10 at the light-emitting point. The drive assembly includes a drive motor 6 and a reduction box 7 (gear reduction); Figure 12 The points through which the light beams 10 all pass are the monitoring points 11 for placing the sample.
[0064] The LED light or laser light is controlled by the controller (Raspberry Pi, microcontroller, DSP chip, FPGA chip or computer) to control the switch of the LED light or laser light, and emit light beams at each light-emitting point.
Embodiment 3
[0066] The difference from the other embodiments is that the light source includes a terminal device with a display screen, the light-emitting points are arranged on the display screen, and the display screen emits a light beam by sequentially lighting each light-emitting point, and The rest of the display is dimmed as each light-emitting point emits a beam of light. The terminal device may be a terminal device with a display screen such as a tablet computer and a mobile phone.
