Abstract

The invention discloses a close-range laser camera which is composed of an imaging lens, a CMOS image sensor, a DSP, a fan, a laser light supplementary lamp, a photosensitive device and a power driver. The close-range laser camera is characterized in that the laser light supplementary lamp comprises an optical homogenizing lens, a laser light source and a cooling fin, the imaging lens is connected with the CMOS image sensor, the CMOS image sensor is connected with the DSP, the laser light supplementary lamp is connected with the photosensitive device, the photosensitive device controls the laser light supplementary lamp to be turned on and off, the power driver provides power for all module devices, and the fan dissipate heat of all the module devices. The optical homogenizing lens is adopted to homogenize laser beams, and therefore the close-range laser camera can achieve close-range night-vision monitoring under a glimmer environment or a total dark environment without light.

Description

technical field [0001] The invention belongs to the technical field of security video monitoring and relates to a short-distance laser camera. Background technique [0002] At present, the development direction of video surveillance is outdoor, the development direction of outdoor monitoring is night vision, and the development direction of night vision is infrared. This trend is becoming more and more obvious. With the increasing demand for night vision monitoring in security monitoring system engineering, infrared cameras have entered the mainstream market of cameras, and sales are increasing day by day. Problems in the application of infrared night vision technology are gradually exposed. [0003] With the technological progress and development of laser infrared lamps, laser infrared lamps are very suitable for specific market needs and become the best light source products for medium and long-distance night vision monitoring. At present, the existing laser infrared came...
