Abstract:
1. A light source and detecting device thereof, comprises: a housing having an accommodating space and one end of the housing has a first opening, a second opening and a through hole; a printed circuit board received in the accommodating space for carrying following units; an optical fiber connector, one end thereof is exposed outside of the first opening and the optical fiber connector is provided with a transmitting end and a receiving end for being coupled with an optical fiber; a laser diode coupled with the optical fiber connector; a laser driving module coupled with the laser diode for driving the laser diode; a light coupling device provided in the optical fiber connector; a light detecting module coupled with the light coupling device for detecting a light signal coupled by the light coupling device and converting the light signal to an analog signal; an analog-to-digital converter coupled with the light detecting module for receiving the analog signal and converting the analog signal to a digital signal; a micro controlling device coupled with the laser driving module, the analog-to-digital converter and the light detecting module; a stroke switch coupled with the micro controlling device and exposed outside of the through hole; and a displaying device coupled with the micro controlling device and exposed outside of the second opening; wherein, when the stroke switch is pressed, the light detecting module is activated according to a determination made by the micro controlling device then a light signal coupled by the light coupling device is detected by the light detecting module, the signal is then displayed on the displaying device after being converted by the analog-to-digital converter or the laser diode is driven by the laser driving module and a laser source is therefore emitted; wherein the light detecting module is directly electrically connected to the light coupling device, the analog-to-digital converter, and the micro controlling device; wherein the laser driving module is directly electrically connected to the laser diode and the micro controlling device.
