Description

Succour terahertz detector in a kind of field

Technical field

This utility model is related to life detectors field, more particularly to a kind of field rescue terahertz detector.

Background technology

THz ripples (THz wave) or referred to as THz rays (Terahertz ray) are the just quilts from the eighties of last century middle and late stage eighties Definite designation, before this scientists will be referred to collectively as far ir ray.THz wave refers to frequency in 0.1THz to 10THz The electromagnetic wave of scope, wavelength probably 0.03 to 3mm scopes, between microwave and it is infrared between.

As soon as in fact, before 100 years, there is scientist to be related to this wave band.At 1896 and 1897, Rubens and Nichols relate to this wave band, and infrared spectrum reaches 9um and 20um, there is the record for reaching 50um again afterwards. Last 100 yearses time afterwards, far-infrared technique achieves many achievements, and industrialization.But it is related to terahertz wave band Result of study and data are considerably less, are mainly limited by effective Terahertz generating source and sensitive detector, therefore this ripple Section is also referred to as THz gaps.

With the series of new techniques eighties, the development of new material, the development of particularly ultrafast technology so that obtain broadband Stable pulse THz sources become a kind of quasi- routine techniquess, and THz technologies are developed rapidly, and interior at the international level start one THz research booms.

At present, terahertz emission reached in the world following common recognition, i.e. Terahertz be it is a kind of it is new, have many unique excellent The radiation source of point；Terahertz Technology is a very important intersection Disciplinary Frontiers, to technological innovation, the national economic development and state Family has safely provided a very tempting opportunity.Why it can cause people widely to pay close attention to, have so many answering With, firstly because the tera-hertz spectra of material includes the physics and chemical information for enriching very much, so research material is at this The spectrum of wave band is significant for the exploration of the structure of matter；Secondly because terahertz pulse light source and conventional light source phase Than with many unique properties.The reason for people's concern THz technologies is THz ray generally existings, is people's knowledge of natural environment circle Effective clue and instrument.But relative to the electromagnetic wave of its all band is such as infrared and microwave, to its understanding and using non- It is often deficient.Absorption of many nonmetallic non-polar materials to THz rays is less, therefore with reference to corresponding technology so that detection Material internal information is possibly realized.For example, ceramics, hardboard, plastic, foam etc. be to THz electromagnetic radiation it is transparent, because This THz technology can be as the unionized of x-ray and relevant complementary radiation source, for the safety prison in the place such as airport, station Survey, such as detect hiding smuggled goods and weld situation including firearms, explosive and drugs etc., and for integrated circuit Detection etc..Polar substancess are stronger to the absorptance of THz electromagnetic radiation, particularly water, should adopt various measures in THz spectral techniques The impact of moisture is avoided, but in THz imaging techniques, it is possible to use this characteristic differentiates the different conditions of biological tissue, than Such as the distribution of fat and muscle in animal tissue, the degree of injury of human body burned part, and the moisture of plant leaf blade tissue are diagnosed Content distribution etc..THz imaging technology compared with the imaging technique of its all band, the resolution of the detection image obtained by it (ultrasonic, infrared, x-ray technology can also improve image resolution ratio, but millimeter-wave technology is but to have significantly increase with the depth of field It is not significantly improved).In addition Terahertz Technology also has the characteristic of many uniquenesses, such as there is less dissipating in material heterogeneous Penetrate, can detect and measure moisture content etc..Not only signal to noise ratio is high for terahertz light spectral technology, and promptly sample can be constituted Slight change make analysis and differentiate, and terahertz light spectral technology is a kind of noncontact measurement, is enabled it to half-and-half The physical message of conductor, thin dielectric film and body material is fast and accurately measured.In view of the characteristics of THz rays, will give Far-reaching influence is brought in the fields such as communication, radar, astronomy, medical imaging, the identification of biochemistry article, materialogy, safety inspection, And then the productive life of change people.There is article《The research of THz communication technology and prospect》,《Chinese laser》, 2009,36 (9)：2213-2233 susceptible of proof above characteristics.

On market common detector be the technology such as infrared, far infrared as detection means, principle be by sensing people Body sends the electric field (being produced by heart) of intrasonic electric wave generation to find the position of " living person ".And this kind of survey meter has one Individual problem, is exactly life detectors cannot determine it is a few individuals, and can only determine the sign of life of people, more next in animal life The today being more taken seriously, people usually can together go out to play with pet dog, pet cat, now in the event of dangerous situation, search and rescue Difficulty it is just much larger.This utility model utilizes the materials such as wall, timber to pass through THz, and human body, animal include a large amount of water Point, the characteristic of THz is not through, a kind of new field rescue terahertz detector is designed, to solve the above problems.
