Embodiment Construction

[0009] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0010] A night vision device with ranging function, such as figure 1 As shown, it includes a pulsed laser and an ICCD camera with a gate, and the ICCD camera can realize range-gated imaging; a range-gated synchronous controller is arranged between the pulsed laser and the ICCD camera, so The range gating synchronous controller can make the pulse of the pulsed laser and the ICCD camera cooperate correctly in timing, and separate the background radiation caused by backscattering at different distances and the useful signal reflected back by the target in time sequence, so that the detected The useful signal reflected by the target arrives at the camera and forms an image just within the working time of the camera gating. The distance gating synchronous controller is a synchronous control circuit, and the synchronous contr...

Abstract

The invention discloses a night-vision device with ranging function, and belongs to the field of monitoring devices. The technical scheme is that: the night-vision device comprises a pulse laser and an ICCD camera with a gate, wherein the ICCD camera can realize range-gated imaging; a range-gated synchronous controller is arranged between the pulse laser and the ICCD camera; the range-gated synchronous controller can make pulses of the pulse laser and the ICCD camera correctly matched on time sequence, separate useful signals reflected by background radiation and an object due to back scattering in different ranges according to the time sequence, so that the useful signals reflected by the detected object reach the camera and are imaged just in the gate working time of the camera. The night-vision device has the advantage that: the night-vision device automatically measuring the range between the camera and the object through the pulse laser and the ICCD camera with the range-gated imaging function, and makes the monitoring more effective.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a night vision device with a distance measuring function. Background technique [0002] Laser night vision devices have the advantages of low power consumption and long range. As an emerging night vision technology, they have been widely used in the market. Generally, the laser night vision device adopts continuous laser illumination, and the laser beam enters the CCD camera after being reflected by the target, and the target is imaged. This night vision device can only detect the target but cannot detect the target distance. Contents of the invention [0003] The present invention aims at the shortcomings of the prior art, and provides a technical solution of a night vision device capable of ranging function. Automatic measurement of the distance between. [0004] The present invention is achieved through the following technical measures: a night vision device with ranging function, w...
