[0041] Further, such as Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the structure of the infrared ranging system of the present invention. Figure 3 The figure is a schematic diagram of the structure circuit principle of the infrared ranging system of the present invention.
