【摘要】 由于红外线兼有电磁波和光的特性，在红外光的发射、接收系统中采用编码、译码集成电路可大大提高其抗干扰性。但在实际应用上，由于红外管的发射有－３０°的立体角，在特定场合，会造成光的干扰，从而使系统误运行。利用光路的一一对应关系，较好地解决了这一难题。更多还原

【Abstract】 As known that the noiseproof feature of a infrared emissing and receiving system will be highlyonereased bt using the encoding and decrypting technique for the infrared light with the properties of both electric-magnetic wave and light wave. However,in actual applications, there is a transmitting tube with 30° solid angle which can make wave interference and so make error operatting By means of one-to one mapping relations of light path, the difficult key has been resolved.更多还原
