<p>The invention relates to a tester for adjusting and checking up laser sensors. According to the invention, the tester comprises an electronic block () to be connected to a laser sensor () to be checked up, providing it with the supply voltage and with a serial connection for acquiring data regarding the characteristics of a received laser signal, an integrating sphere () which, by its characteristics, achieves high attenuation of the laser signal, a Q-switch pulse laser emitter () which emits on the wavelength of 1.06μm, with its own source and a set of filters achieving attenuation within the range of 10...0.001%, another Q-switch pulse laser emitter () which emits on the wavelength of 1.54μm with its own source and a set of filters achieving attenuation within the range of 10...0.001%, an oscilloscope () with memory, with two channels, having an operating frequency of at least 200 MHz, and an electronic device () for synchronization of the oscilloscope time base with the laser pulses.</p> |
