Title: Particle detection sensor
Inventor: NISHIKAWA NAOYUKI
IPC: G08B17/107
Filed: 2002-10-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a particle detection sensor which can prevent the missing detection of particles and reduce the influence of noises.  <P>SOLUTION: The sensor comprises an oscillating circuit 8 whose output changes in a sinusoidal form with time, a light emitting means 1 which irradiates light beam having a strength according to the output of the oscillating circuit 8 onto a region to be monitored, and a light receiving means 2 on which the light scattered by particles P suspended in the region to be monitored is incident to generate an output according to the incident light quantity. The output of the light receiving means 2 is input to a synchronous detecting circuit 7 together with the output of the oscillating circuit 8. The synchronous detecting circuit 7 synchronizes the output of the light receiving means 2 with the output of the oscillating circuit 8 to perform heterodyne detection. According to the above structure, the light emitting means 1 continuously emits light so that the missing detection of the particle P can be prevented. Further, since the strength of light beam is changed in a sinusoidal form with time and the output of the light receiving means 2 is synchronously detected, the influence of noises can be reduced as compared with the case where the strength of light beam is constant.  <P>COPYRIGHT: (C)2004,JPO
