Description
Technical field
The present invention relates to a kind of detection device, especially a kind of laser range finder lens contamination detection device.
Background technology
In certain application environments of laser range finder, it is exposed transmitting and reception window lens be easily infected with ash,
The pollutants such as soil, the launch window of laser range finder and the cleannes for receiving window lens have greatly the performance of range finder
It influences, if eyeglass is contaminated, the range capability of range finder can be seriously affected.
Invention content
To solve the above problems, the present invention provides a kind of a kind of laser ranging that can be detected eyeglass automatically and whether be contaminated
Machine lens contamination detection device, specific technical solution are：
A kind of laser range finder lens contamination detection device, including isolation lens, echo camera lens energy back receiving sensor and
Emit camera lens energy back receiving sensor；The high anti-low lens of isolation are mounted on laser emission channel and echo reception leads to
Between road, the echo camera lens energy back receiving sensor is mounted in echo reception channel, and the transmitting camera lens energy is anti-
Receiving sensor is presented to be mounted in laser emission channel.
Preferably, the isolation lens are lens group or prism.
On laser emission channel Laser emission window lens are mounted on equipped with Laser emission window lens, laser emitter
Rear, transmitting camera lens energy back receiving sensor are mounted on the side of laser emitter；Echo is housed on echo reception channel
Window lens are received, echo reception window lens rear is equipped with echo laser detection system, echo camera lens feedback reception sensor
Mounted on the side of echo reception channel；Laser emission channel is installed side by side with echo reception channel, the high anti-lens installation of isolation
Between laser emission channel and echo reception channel, and the light of laser emission channel is enable to enter by the isolation lens
Into the echo camera lens energy back receiving sensor in echo reception channel.
Since all eyeglasses are impossible to 100% transmitance, the laser beam that laser transmitter projects go out exists
Laser emission window lens can generate small scattering light echo, which can be in transmitting camera lens energy back receiving sensor
Upper to generate certain detecting voltage, the voltage swing is directly proportional to light echo power, because laser emitting power is generally steady state value,
Laser emission window lens are also invariable, therefore, Laser emission window lens in the case that not comtaminated and contaminated,
The voltage that transmitting camera lens energy back receiving sensor is detected is different, if eyeglass is contaminated, detecting voltage
Can be significantly raised, the threshold voltage of this detecting voltage and systemic presupposition compares, and is such as more than certain value, then can trigger alarm signal
Number.
It is lens group or prism that lens, which are isolated, and while Laser emission, it is saturating by the isolation equally to have faint light
Mirror projects laser pick-off channel, by the adjusting to lens position is isolated, transmitted light is enable to get to echo reception window mirror
On piece similarly also can feed back a part of laser energy by echo reception window lens and receive sensing to echo camera lens energy back
On device, it can judge whether echo reception window lens are contaminated by same judgment mode, if receiving pollution, touch
Activating alarm.
Compared with prior art the invention has the advantages that：
A kind of laser range finder lens contamination structure of the detecting device provided by the invention is simple, reliable, ingenious, can detect mirror automatically
Whether piece is contaminated, and is such as contaminated, then alarm signal can be sent out to user by warning device, to prompt user couple
Eyeglass is cleaned, and prevents the range capability of pollution effect range finder.
Figure of description
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
In conjunction with attached drawing, the invention will be further described.
As shown in Figure 1, a kind of laser range finder lens contamination detection device, anti-including isolation lens 2, echo camera lens energy
Present receiving sensor 5 and transmitting camera lens energy back receiving sensor 6；Laser emission window mirror is housed on laser emission channel 9
Piece 3, laser emitter 7 are mounted on the rear of Laser emission window lens 3, and transmitting camera lens energy back receiving sensor 6 is installed
In the side of laser emitter 7；Equipped with echo reception window lens 1 on echo reception channel 8, after echo reception window lens 1
Side is mounted on the side of echo reception channel 4 equipped with echo reception channel 4, echo camera lens energy back receiving sensor 5；Laser
Transmission channel 9 is installed side by side with echo reception channel 8, and isolation lens 2 are mounted on laser emission channel 9 and echo reception channel 8
Between, and the light of laser emission channel 9 is enable to enter in echo reception channel 8.
It is lens group or prism that lens 2, which are isolated,.
Since all eyeglasses are impossible to 100% transmitance, the laser beam that laser emitter 7 is launched exists
Laser emission window lens 3 can generate small scattering light echo, which can receive sensing in transmitting camera lens energy back
Certain detecting voltage is generated on device 6, the voltage swing is directly proportional to light echo power, because laser emitting power is generally constant
Value, Laser emission window lens 3 are also invariable, and therefore, Laser emission window lens 3 are in not comtaminated and contaminated feelings
Under condition, the voltage that transmitting camera lens energy back receiving sensor 6 is detected is different, if Laser emission window lens 3
Contaminated, then its detecting voltage can be significantly raised, and the threshold voltage of this detecting voltage and systemic presupposition compares, and is such as more than certain
Value then can trigger alarm signal.
It is lens group or prism that lens 2, which are isolated, and while Laser emission, it is saturating by the isolation equally to have faint light
Mirror 2 projects laser pick-off channel, by the adjusting to 2 position of isolation lens, transmitted light is enable to get to echo reception window
On eyeglass 1, a part of laser energy similarly can be also fed back by echo reception window lens 1 and is received to echo camera lens energy back
On sensor 5, it can judge whether echo reception window lens 1 are contaminated by same judgment mode, if receiving dirt
Dye, then trigger alarm.
