Embodiment Construction

[0025] figure 1 It is a schematic diagram of the circuit structure of the laser energy meter. The laser energy meter of the present invention includes a DC conversion circuit, an energy probe, a control circuit, a display circuit, a storage circuit and a remote communication interface.

[0026] The DC conversion circuit is connected to the external power supply, and the DC voltage of ±5V is converted by an isolated DC-DC module. These two DC voltages supply power to each part of the laser energy meter, and at the same time supply power to the external energy probe. The functional ground of the internal circuit of the energy meter is isolated from the functional ground of the external power supply, which greatly reduces the interference from the input power supply. The external power supply is a DC power supply with a voltage range of 18V-36V, preferably 24V / 0.5A, which makes it more convenient for users to choose a power supply.

[0027] The energy probe adopts a high-precis...

Abstract

The invention relates to the technical field of laser, in particular to a laser energy meter and an automatic dormancy and awakening method thereof. The automatic dormancy and awakening method for the laser energy meter comprises the following steps of: 1, starting a control circuit of the laser energy meter and performing the control circuit self-check; 2, enabling the control circuit to enter a working mode; 3, judging whether the control circuit receives an external triggering signal within a preset time period, if the control circuit does not receive the external triggering signal within the preset time period, executing the step 4, otherwise, not executing any operation; 4, enabling the control circuit to enter a dormancy mode; and 5, judging whether the control circuit receives the external triggering signal, if the control circuit receives the external triggering signal, executing the step 2, otherwise, not executing any operation. By the automatic dormancy and awakening method, the laser energy meter enters the dormancy mode or the working mode according to judgment whether the control circuit receives the external triggering signal within the preset time period, so that circuits of the laser energy meter are in the dormancy mode when the laser energy meter is not used for performing measurement, and the energy consumption is reduced greatly.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a laser energy meter and its automatic sleep and wake-up method. Background technique [0002] With the development of optoelectronic technology, the application field of laser technology is expanding day by day, and the corresponding laser parameter metrology test has been paid more and more attention. In the basic research and clinical application of laser medicine, the amount of laser radiation is directly related to its effect on tissues. To accurately control the amount of laser radiation, it must first be accurately measured. In the measurement of laser radiation, the measurement of output power (for continuous or quasi-continuous lasers) or energy (for pulsed lasers) is the most basic and important. Therefore, laser energy meters have become one of the important tools for quantifying laser radiation. one. [0003] However, when the existing laser energy meter is not perf...
