Technical Field

The utility model relates to a stripe camera operating condition detection device technical field, in particular to stripe camera with from triggering operating condition and detecting.

Background

The streak camera is a transient optical measurement instrument that measures the phenomenon of ultrafast light and combines intensity, time and spatial (or wavelength) information at the same time. The method has wide application, such as the fields of fluorescence life measurement, optical communication and quantum device response measurement, laser ranging, laser radar, laser induced discharge, high-energy laser nuclear fusion and the like, and has irreplaceable effect in the research of ultrafast phenomena in the field of basic frontier. The physical experiment environment of the high-power laser device and the high-power Z-ping device is extremely complex, some scientific research experiments need to detect or check the working state of the stripe camera before testing, whether the working state of the camera is normal or not is confirmed, and the dynamic working of the stripe camera can be carried out only by triggering. Therefore, the triggering of the operation of the stripe camera system becomes an important prerequisite for the operation of the stripe camera. The working configuration of the currently commonly used stripe camera system is shown in fig. 1 below.

As can be seen from fig. 1, the fringe camera system needs to provide a trigger signal from the outside to determine the scanning operation of the camera, and the conventional trigger method is to use an electric pulse with a certain amplitude and a certain pulse width as a trigger signal to input into the camera, and trigger the scanning circuit to operate to implement the fringe camera, and specifically there are two methods. An electric trigger is characterized in that a path of electric pulse signal is synchronously led out from a laser, the signal is processed through a trigger delay unit and then input to a stripe camera to trigger the camera according to a set mode, and whether the working state of the stripe camera is normal or not is judged by monitoring the result of a slit image on a fluorescent screen. And the other light triggering is to lead out one path of light through a laser light path or directly irradiate a Photodiode (PIN) by utilizing a light-emitting phenomenon, generate electric pulses under the action of a photoelectric effect, process the signal through a triggering and time-delay unit and input the signal into the stripe camera to trigger the camera, and judge whether the working state of the stripe camera is normal or not by monitoring the result of the slit image on the fluorescent screen.

As can be seen from the structure diagram of the conventional stripe camera triggering system, the triggering mode generally needs to be performed by using external devices, such as a laser or a light source, an optical path system, a PIN, a triggering delay module, and the like, and the peripheral triggering device also increases the cost and needs to be completed by building a system. In actual use or camera debugging calibration, some fields or applications do not have or cannot adopt the peripheral equipment, and the working state of the camera is inconvenient to monitor and even cannot be completed.
