Abstract
An infrared detector comprises an optical filter, a sensing system, a circuit system, a display system, a power system and a packaging housing. The optical filter comprises a Fresnel lens and a parabolic reflector. The sensing system comprises a pyroelectric sensor chip and a semiconductor refrigerator. The optical filter realizes wider detecting range and higher focusing accuracy of the infrared detector. Each assembly of the infrared detector is connected with the packaging housing through a corresponding fixing seat. Simple mounting and more convenient assembly changing are realized.
Description
Technical field
The present invention relates to detector field, particularly relate to a kind of infrared eye.
Background technology
In recent years, China's Aero-Space cause, the developing rapidly of industrial and agricultural production and science and technology, infrared eye technology is got more and more, is applied more and more widely in different field.Due to infrared eye except volume itself is little, lightweight, can identify except the advantages such as invisible light, also there is high detectivity simultaneously, substantially wavelength is not limited, can normally use under room temperature and reliable structure, there is the advantages such as good stability, therefore, had in fields such as aerospace field, national defense construction, industrial and agricultural production, communications and transportation and scientific research systems and applied widely.
Because Fresnel Lenses machine-shaping is convenient, cheap therefore in the market many infrared eyes all use Fresnel Lenses as optical filter, but generally common Fresnel Lenses infrared eye investigative range is narrower, part infrared eye installs more complicated, can not carry out single component replacing, later maintenance cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of simple and direct, practical infrared eye, to reach expansion investigative range, improve detection accuracy, single component is changed simple, reduces later maintenance cost.
For realizing object of the present invention, there is provided following technical scheme: a kind of infrared eye, comprise optical filter, sensor-based system, Circuits System, display system, power-supply system and encapsulating housing, described optical filter is fixed on filter holder and is positioned at encapsulating housing front end, described sensor-based system is fixed on sensing holder and is positioned in the middle part of encapsulating housing, described display system is fixed on display holder and is positioned at encapsulating housing rear portion, described Circuits System is connected with sensor-based system and display system, between sensor-based system and display system, described display system comprises display screen drive plate and display screen, described power-supply system is positioned at below display system, described optical filter comprises Fresnel Lenses and parabolic mirror, described optical filter comprises Fresnel Lenses and parabolic mirror, described Fresnel Lenses is the multilayer multiple viewports Fresnel Lenses that toroidal Fresnel Lenses cuts into the regular arrangement of sheet and forms, the number of plies is 1-5 layer.
Comprise heat as preferred described sensor-based system and release sensing chip and semiconductor cooler, described heat is released sensing chip and is comprised the contrary responsive unit of pyroelectricity of two electrodes in series or in parallel with each other, and heat is released sensing chip and is connected with Circuits System by signal leading-out terminal.
