摘要 ：
Photoelectric detection technology is the main technology of photoelectric information technology is based on the laser infrared optical fiber and other modern optoelectronic devices based on the radiation as the photoelectric detector receives light radiation is converted to the electrical signal of object light is detected,then after the subsequent processing,obtaining useful information technology.In this paper,the nondestructive detection technique based on optoelectronic technology overview.Mainly discusses several independent type photoelectric smoke fire detection alarm,infrared detection technology,photoelectric pulse sensor,nondestructive testing technology,their principle and application range are discussed.
