Description
Technical field
The utility model belongs to range radar technical field, specifically, there is provided a kind of new transmitting-receiving integrated to sweep
Retouch range laser radar.
Background technology
The characteristics of laser scanning and ranging radar is high directivity and the high brightness using laser, emitted light path, which is irradiated to, to be turned
It is scanned on mirror, receiving module receives determinand reflection echo, and transmitting arteries and veins is calculated by timing module and control module processing
The time interval between pulse is rushed and received to obtain the distance between testee, the contour curve of target object is by being connect
A series of pulse trains for receiving determine.
The light path of two dimensional laser scanning sensor uses coaxial transmitting and reception mostly at present, and transmitting first is anti-by tilting mirror
Penetrate and be scanned, then tilting mirror receives echo, then received lens are focused, and the program easily produces transmitting illumination and is mapped to
Other positions inside tilting mirror or radar and received by receiving module and produce interference signal, therefore it is required that transmitting and receive should be coaxial
Again independently of each other, and with the extension of laser scanning and ranging radar application, its compact-sized and volume contracting is required in trend
It is small.
Utility model content
To solve the above problems, the utility model proposes a kind of transmitting-receiving integrated scanning laser range radar, including：Hair
Module is penetrated, optical fiber, launches shaping lens, receiving lens, 45 ° of reflective mirrors, balancing weight, receiving module, motor, code-disc and coding
Device；
In the horizontal direction, the central shaft of transmitting shaping lens, receiving lens and 45 ° of reflective mirrors is on the same line；Vertical
To direction, the detector center of receiving module, the central shaft of 45 ° of reflective mirrors and motor shaft is on the same line；Receiving lens are erected
Straight to be arranged on before 45 ° of reflective mirrors, receiving lens are assembled for receiving reflection echo signal, after reaching 45 ° of reflective mirrors,
Aggregation light is reflexed into reception device to receive；Aperture is provided with the inclined-plane of 45 ° of reflective mirrors, optical fiber carries out penetrating light in fact through aperture
Conduction, collimation transmitting light transmitting is carried out via the transmitting shaping lens.
Preferably, the aperture is located at the center of 45 ° of reflective mirrors.
Preferably, the transmitting-receiving integrated scanning laser range radar also includes scan module, timing module, and control mould
Block.
Preferably, the transmitter module, optical fiber, shaping lens, receiving lens, 45 ° of reflective mirrors, code-disc and balancing weight are launched
