Visible-infrared bi-pass camera

Abstract

The invention discloses a visible-infrared bi-pass camera, which comprises an imaging device, an infrared light-path access, a visible light light-path access, an FPA (floating-point accelerator) chip, a visible light reading light-path and an optical receiver, wherein the imaging device comprises a visible-infrared imaging objective lens; the visible-infrared imaging objective lens comprises a light splitting device; the infrared light-path access is used for imaging the infrared light obtained from the light splitting of the light splitting device on the FPA chip through the infrared light-path access; the visible light light-path access is used for reading the image information on the FPA chip and reflecting the image information on the optical receiver; and the imaging device is used for imaging the visible light obtained from the light splitting of the light spitting device on the optical receiver through the visible light light-path access. According to the visible-infrared bi-pass camera disclosed by the embodiment of the invention, the splitting of the visible light and the infrared light on a light-path space is realized through light splitting devices, the infrared light imaging is realized by using the FPA chip, and the imaging information is read by the visible light light-path access and is displayed on the optical receiver subsequently, so that the system cost is reduced, and meanwhile the power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of imaging instruments, in particular to a visible-infrared dual-pass camera. Background technique [0002] With the increasing popularity of monitoring and camera systems in the commercial and civilian fields, infrared cameras (surveillance cameras) are widely used in various fields to protect social security. For each different application field, different types of surveillance cameras are required to meet the requirements. As the public has higher and higher requirements for monitoring products, such as 24-hour monitoring and low prices, in order to adapt to changes in market demand, manufacturers are competing to develop visible and infrared day and night dual-purpose cameras. [0003] At present, domestic day and night cameras still need to be equipped with certain lighting equipment or infrared equipment, and use the optical path system that can simultaneously image infrared light and visible light an...
