Abstract: |
Laser had a wide range of applications in the automotive mechanical industry, electronic communications, and medical devices. The field of measurement and indication were often by the naked eye to observe its action effect in the past, but the error rate is larger. This article describes a device that could replace the human eye, improve accuracy of measurement and indication. The device included laser circuit, detection circuit and signal processing or directed circuit of three parts. Through the optical transistor in the detection circuit to detect the laser (Red Light 650nm) which emits from laser circuit, and transmit the detected signal from the detection circuit by the wireless transmitter part (SC2262).Tested by experiment, the device can effectively detect the laser to improve the accuracy of measurement and instructions, the buzzer switch was turned on, then sounds. Instead, you can view the hand-held receiver to receive instructions, to judge the working state of detection head. Then, through signal processing or direct circuit to receive and treatment, made appropriate instructions.
