Abstract

A rapid switching system of long-distance and short-distance measurement modes for a laser ranging telescope includes a received signal amplification module, a received signal detection module, a driving voltage switching module, and an MCU module. An output terminal of the received signal amplification module is electrically connected to an input terminal of the received signal detection module, an output terminal of the received signal detection module is electrically connected to the MCU module, an input terminal of the driving voltage switching module is electrically connected to the MCU module, and an output terminal of the driving voltage switching module is electrically connected to the received signal amplification module. The MCU drives the driving voltage switching module to output a low or high voltage by outputting a high or low control voltage, thereby switching the laser ranging telescope into the short-distance or long-distance measurement mode.
