Because the method for so far, being directed to the detection of beam collimation degree has following two：
One is to utilize talbot itself imaging and gatestack phenomenon：I.e. when grating is illuminated by a monochromatic collimated light beam,
Accurate grating itself picture will be formed in the specific plane of optical propagation direction, if placing second piece at grating itself picture
Grating, then it is observed that Moire fringe.The non-aligned of light beam can cause the change of Moire fringe.Conversely, by Moire fringe
Change, you can the collimation of detection light beam.On dual linear grating, spiral grating, gradually shape grating and circular grating in the wrong enter
The research of row beam collimation degree detection is found, is better than the grating of other shapes using circular grating.
Another is to utilize shearing interference method：Be most widely used in shearing interference method be the silent base of a fruit clapboard shearing it is dry
Interferometer, it is using the interference fringe benchmark as beam collimation parallel with datum line, and the interference fringe of uncollimated rays and base
There will be an inclination angle between directrix, later Kothiyal etc. is improved the technology, introduces self-reference alignment method.
Existing both approaches all exist for the measurement of beam collimation degree makes small (the big diverging of complicated, measurement range
Spend light beam), it is with high costs the shortcomings of.
The beam collimation degree detection components 100 that embodiments of the present invention 1 are provided, using simple beam-splitting structure, pass through
Infrared non-visible collimated light 18 to be detected is divided into two, make wherein light beam by shorter light path be just focused lens gather
Jiao, detects through photo-detector and shows result of detection, so as to analyze current infrared non-visible collimated light 18 to be detected
The angle of divergence.
After infrared non-visible collimated light 18 to be detected is divided into two, the light path of two-beam is differed, after beam divergence
Spot radius also change, the two-beam will form different forms after condenser lens is focused on, and comparative analysis can be obtained
The convergence form for obtaining the infrared non-visible collimated light 18 to be detected still dissipates form, so as to obtain more comprehensive collimated light
Characteristic.
The beam collimation degree detection components 100 that embodiment of the present invention 1 is provided have an advantageous effect in that：Reasonable in design,
It is simple in construction, the characteristic of more comprehensive collimated light can be obtained, practicality is good, and cost is relatively low.
Embodiment 2
Embodiment of the present invention 2 provides a kind of beam collimation degree detection method, the light provided using above-mentioned embodiment 1
Beam collimation detection components 100, are described as follows：
First, show that result is analyzed using single detector：
Infrared non-visible collimated light 18 is injected from light admission port 132, the infrared non-visible collimated light 18 is in spectroscope 14
It is divided into two on light splitting surface 143, wherein, 1/2nd light is projected from light splitting surface 143, poly- by the first lens 153
Jiao, the first detector 163 detects the light that the first lens 153 are collected into, and electric signal is converted into optical signal and is visited to first
The hot spot that survey device 163 is detected is made, to the processing of quantity degree, to form first group of electric signal.
The single detector detects the light that condenser lens is collected into, can be with according to the degree of convergence of hot spot on detector
Judge the degree of divergence of collimated light, and calculate the angle of divergence of current collimated light.
As Figure 4-Figure 7, take the collimated light of four groups of different angles of divergence incident, with the first lens 153 and the first detector
163 be analysis target, specific as follows：
Detected when taking 0mrad, 1mrad, 2mrad and 3mrad collimated light incident respectively on the first detector 163
Hot spot irradiation level schematic diagram (is made to the processing of quantity degree), and the different angles of divergence just can be intuitively found out very much from Fig. 5-Fig. 8
Collimated light hot spot it is different.
0mrad collimated light is theoretically perfect collimated light, collimated light of the degree of convergence than the 1mrad angle of divergence of hot spot
More preferably.First lens 153 (i.e. aspheric collimation lens) are directed to for entirely collimated light beam, have made spherical aberration processing,
So, hot spot degree of convergence is deteriorated, and is entirely as caused by collimated light beam divergence.As the angle of divergence is bigger, the first detection
The hot spot that device 163 is detected more dissipates.
Then analyze by the converted electric signal of optical signal, and according to the data of hot spot irradiation level, can analyze completely
The size of the angle of divergence of current collimated light.
Secondly, the comparative analysis of two detectors of setting is passed through：
After 1/2nd other light reflects from light splitting surface 143, by the outgoing of the face of being all-trans 145, by the second lens
154 focus on, and the second detector 165 detects the light that the second lens 154 are collected into, and electric signal are converted into optical signal and to the
The hot spot that two detectors 165 are detected is made, to the processing of quantity degree, to form second group of electric signal.
Due to the hot spot detected by single detector, the angle of divergence of current collimated light can be analyzed, and sets another
The effect of road light splitting, be detect outgoing collimated light be outwards dissipate or toe-in.
As shown in figure 8, the three kinds of forms occurred by collimated light：Ideal state, diverging state and convergence state.
If diverging state, then the focal position formed by condenser lens appears in the rear of detector, and such as
Fruit is convergence state, then the focal position formed by condenser lens appears in the front of detector, two kinds of collimated light shapes
Into hot spot form also can be different.
For diverging state collimated light：Beam cross section radius can become larger with the propagation of light, and focusing on again can be more difficult,
Relative to desired collimation light, after condenser lens, its Focus Club falls behind preferable focus (i.e. detector photosurface),
A hot spot for having certain size is formed on the detector.So, two-way light is formd by light splitting to same collimated light to be measured
Beam, beam distance condenser lens is near all the way, and another great distance, and between the two when by condenser lens, its hot spot section is
Different, the longer beam and focus section of light path can be bigger, and the hot spot that detector is received will also become much larger.
For convergence state collimated light：Collimated light with diverging state is just the opposite, and light path is more remote, the hot spot section meeting of collimated light
Smaller, relative to desired collimation light, the Focus Club for restraining the collimated light of state falls in the front of preferable focus, equally also can be in detection
A hot spot for having certain radius size is formed on device, and relative to diverging state collimated light, restrains the collimated light of state, light path is got over
Short, the hot spot section of formation is bigger, and the hot spot that detector is detected is also bigger, according to the contrast between two light beams, can be with
Obtain convergence and the degree of divergence of hot spot.
It is the irradiation of different shape light beam (its angle of divergence is 1mrad) hot spot on the detector as shown in Fig. 9-Figure 12
Degree, wherein, Fig. 9 and Figure 10 are that the hot spot irradiation level imaging display for the collimated light formation for dissipating state (is made at quantity degree
Reason), the difference in size of two hot spots can not be intuitively found out from figure, data can be put with DSP processing procedures
Big processing.
The hot spot irradiation level imaging display for then having the collimated light formation of the convergence state shown in Figure 11 and Figure 12 (also makees logarithm
Measure processing), so as to draw, the spot size that the collimated light beam of short light path is formed after focusing on is bigger.At DSP numerals
Reason, can quantify convergent degree.
The beam collimation degree detection method that embodiment of the present invention 2 is provided is relative to traditional detection method, structure letter
Single, reasonable in design, it is easy to realize, operability is good, and cost is low, the difference brought by different optical path differences, can be conducive to
The characterisitic parameter of more collimated lights is extracted, further optimizes infrared non-visible collimated light 18 to be detected.
It should be noted that in the case where not conflicting, the feature in embodiment in the present invention can be combined with each other.
The preferred embodiment of the present invention is the foregoing is only, is not intended to limit the invention, for this area
For technical staff, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made is any
Modification, equivalent substitution, improvement etc., should be included in the scope of the protection.
