Problems solved by technology

For example, the main manufacturer in this field, the American MAC Company, although its products have their own uniqueness in the appearance of the instrument and the technology of the laser power calibrator, the power that can be tested is relatively small and the range is narrow. With the development of laser technology With continuous progress, the application power of laser is also increasing. Many military laser equipment with high and medium power are difficult to detect, which limits its applicable scope to a certain extent.

Embodiment Construction

[0046] Such as figure 1 As shown, a multi-wavelength laser power calibrating instrument includes a sensor, an instrument host and an optical path locking device;

[0047] The optical path locking device is fixed between the laser source to be tested and the sensor, and the sensor converts the laser power signal emitted by the laser source to be tested into an electrical signal, and transmits it to the instrument host for processing.

[0048] Such as figure 2 As shown, the instrument host is composed of a preamplifier circuit unit, a V-F conversion circuit and a data processing unit; the preamplifier circuit unit receives the electrical signal output by the sensor, filters and amplifies it, and then transmits it to The V-F conversion circuit; the regular pulse signal generated by the V-F conversion circuit is output to the data processing unit;

[0049] The data processing unit is composed of an analog signal processing circuit and a main control CPU;

[0050] Wherein, the ...

Abstract

The invention discloses a multi-wavelength laser power calibrating apparatus and method. The multi-wavelength laser power calibrating apparatus comprises a sensor, an apparatus host and a light path locking device. The light path locking device is arranged between a laser source to be measured and the sensor; the sensor converts laser power signals emitted by the laser source to be measured into electric signals and transmits the electric signals to the instrument host to be processed. The multi-wavelength laser power calibrating method comprises the steps of stability testing, sensitivity testing and the like. According to the multi-wavelength laser power calibrating apparatus and method, optical mechanical and electronic integration is achieved. The operation method is easy and convenient to implement, digital display is achieved, the accuracy is high, and the stability is good. The apparatus is miniaturized and is low in weight so as to be suitable for fast detecting power of a laser appliance during field operations.

Description

technical field [0001] The invention relates to the basic field of laser technology, in particular to a multi-wavelength laser power calibrating instrument and a calibrating method thereof. Background technique [0002] With the continuous advancement of laser technology, lasers are widely used in military fields such as weaponry and field medical equipment. In order to ensure the safety, reliability and stability of laser equipment, regular quality inspections must be carried out on them. Laser power is an important technical parameter of laser equipment, and its accuracy is the main technical index to measure the quality and performance of laser equipment. Therefore, it is particularly important to study a portable, intelligent, multi-wavelength laser power calibrator. [0003] Foreign countries have done a lot of research work on laser power detection for a long time, and with the development of sensor technology in recent years, they have achieved good results in digital...
