Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a schematic flow chart of the spectrum acquisition method with integrated spectrum resolution provided by the present invention is shown in fig. 1, and the spectrum acquisition method with integrated spectrum resolution includes:
step S110, acquiring a target electric signal set output when unknown light irradiates a preset photoelectric conversion array; the photoelectric conversion array comprises an array formed by n photoelectric conversion units according to a preset arrangement mode, and the photoelectric conversion units at each position in the photoelectric conversion array are different from each other.
Step S120, obtaining a target photoresponse curve set output when preset monochromatic light irradiates the photoelectric conversion array; the number of the monochromatic light is m, and the wavelength of each monochromatic light is different.
And step S130, obtaining a target spectrum according to the target light response curve set and the target electric signal set.
Wherein n and m are integers greater than 0, and the values of n and m can be the same or different.
Specifically, each photoelectric conversion unit in the photoelectric conversion array has different response to illumination, the different response of the photoelectric conversion unit to illumination depends on the photoelectric material in the corresponding photoelectric conversion unit, and the different response can be realized by regulating and controlling the chemical composition and the particle size of the photoelectric material. For example, when the photoelectric material includes quantum dot material, perovskite material and organic dye, and is preferably quantum dot material, it is possible to form one photoelectric conversion unit by synthesizing quantum dots of different kinds or different sizes, one quantum dot material (or other materials) constitutes one photoelectric conversion unit, and one photoelectric conversion unit corresponds to only one specific illumination response, thereby realizing different responses of different quantum dots to illumination. Fig. 2 shows an example of a high-resolution tem of a quantum dot nanomaterial as a core material of a photoelectric conversion unit, such as a quantum dot nanomaterial.
In addition, in response to the requirements of the photoelectric conversion array, the element substrate of the photoelectric conversion array may be made of an optically transparent material, for example, when the element substrate is made of an optically transparent flexible material, the photoelectric conversion array may further have flexible characteristics. Furthermore, the pattern of the photoelectric conversion array, and the arrangement and shape (such as pattern) of the specific photoelectric conversion units can be varied, but the design of the element substrate of the photoelectric conversion array is matched with the photoelectric conversion array, and the main materials of the element substrate of the photoelectric conversion array include insulating materials and conductive materials.
Further, regarding the requirements of the photoelectric conversion units in the photoelectric conversion array, it is in principle preferable that the number of the photoelectric conversion units is larger and that the volume of the photoelectric conversion array is smaller, but there is no limitation on the size and shape of each photoelectric conversion unit.
In addition, the n photoelectric conversion units in the photoelectric conversion array can be designed according to different arrangement modes, preferably, the photoelectric conversion arrangement mode with the highest spectral resolution is obtained through optimization by combining an algorithm, each photoelectric conversion unit can respectively generate corresponding electric signals after being illuminated, and the generated electric signals can be output and recorded. Fig. 3 is a schematic diagram of the photoelectric conversion array in a square shape.
In addition, the preset m monochromatic lights may be m standard lights of known intensity and wavelength, the wavelength range of each monochromatic light covers the photosensitive range of the photoelectric conversion array, and the wavelength of each monochromatic light is uniformly distributed within the covered range.
It should be noted that, in the actual execution process, the order of executing step S110 and step S120 may not be limited, for example, step S110 may be executed first and then step S120 may be executed, step S120 may be executed first and then step S110 may be executed, or step S110 and step S120 may be executed at the same time.
According to the spectrum acquisition method integrating spectral resolution, disclosed by the invention, the aim of performing high-efficiency and low-energy spectral resolution on unknown light is realized by acquiring a target electric signal set output when the unknown light irradiates on a preset photoelectric conversion array and a target photoresponse curve set output when the preset monochromatic light irradiates on the photoelectric conversion array, and the problems of overlarge volume, overhigh cost and overlarge energy consumption caused by the fact that a photoelectric detector is required to realize spectral resolution in the traditional method are solved; furthermore, when the photoelectric conversion array comprises an array formed by n photoelectric conversion units according to a preset arrangement mode, the number of monochromatic light is m, and the wavelength of each monochromatic light is different, different wavelengths of the plurality of monochromatic light can be uniformly distributed in the photosensitive range of the photoelectric conversion array, so that the spectral resolution of a target light response curve set generated when the photoelectric conversion array is irradiated by the plurality of monochromatic light is higher, the accuracy of obtaining a target spectrum based on the target light response curve set is reliably guaranteed, and the spectral resolution precision is effectively improved.
In an actual process, when the photoelectric conversion array includes a plurality of photoelectric conversion units and the number of monochromatic lights is m, step S120 may be implemented by:
when the preset monochromatic light is determined to be irradiated on the photoelectric conversion array, acquiring a light response curve generated by each photoelectric conversion unit; wherein the optical response curve comprises curves formed by m electric signals generated by each photoelectric conversion unit respectively.
And arranging the light response curves according to a first preset rule to obtain a target light response curve set.
Specifically, when it is determined that the predetermined monochromatic light is irradiated onto the photoelectric conversion array, a process of obtaining each of the photoresponse curves generated by the photoelectric conversion units, respectively, includes:
when the preset monochromatic light is determined to be irradiated onto the photoelectric conversion array, m electric signals respectively generated by each photoelectric conversion unit are obtained; the m electric signals represent that each photoelectric conversion unit respectively generates electric signals corresponding to m monochromatic lights one by one;
and after the m electric signals are arranged according to a second preset rule, obtaining a light response curve generated by each photoelectric conversion unit respectively.
If n serial numbers from 1 to n are marked on the n photoelectric conversion units, the first preset rule may include the serial numbers or positions of the photoelectric conversion units; the arranging according to the second preset rule may include arranging the m electrical signals differently in terms of a collection band, a collection time, and corresponding monochromatic light.
Specifically, because the wavelength of each monochromatic light is uniformly distributed in the photosensitive range of the photoelectric conversion array, and the position of each photoelectric conversion unit in the photoelectric conversion array is different, when the m monochromatic lights are irradiated onto the photoelectric conversion array, each photoelectric conversion unit can be irradiated by the m monochromatic lights, at this time, m electrical signals corresponding to the m monochromatic lights one by one can be collected in the photosensitive range of each photoelectric conversion unit, the collection process of the m electrical signals all adopts the existing electrical signal collection method, for example, m optical signals are generated when the m monochromatic lights are irradiated onto each photoelectric conversion unit, and then the m electrical signals are respectively subjected to data selection processing, signal amplification processing and analog-to-digital conversion processing to obtain m electrical signals; the photoelectric conversion unit may generate an electric signal by using a photoelectric energy conversion function provided by the photoelectric conversion unit itself, and is not particularly limited herein.
Then, the m electrical signals are arranged according to the signal acquisition wave band, the acquisition time and the difference of the corresponding monochromatic light to obtain the light response curves respectively generated by each photoelectric conversion unit, namely n light response curves generated by the photoelectric conversion array.
Furthermore, after n photoresponse curves generated by the photoelectric conversion array are arranged according to different positions or serial numbers of the photoelectric conversion units, a target photoresponse curve set output when preset monochromatic light irradiates the photoelectric conversion array can be obtained, and the obtained target photoresponse curve set is an n × m dimensional matrix. When m is 30, a set of target photoresponse curves as shown in fig. 4 can be formed. As can be seen from fig. 4, each photoelectric conversion unit corresponds to a different optical response curve.
According to the spectrum acquisition method with integrated spectrum resolution, the target photoresponse curve set with the calibration function is acquired by irradiating the photoelectric conversion array with n monochromatic lights with different known wavelengths, so that accuracy and reliability guarantee are provided for the follow-up spectrum resolution of unknown light.
In the actual processing procedure, the acquiring procedure of step S110 may include:
and when the unknown light is determined to irradiate the preset photoelectric conversion array, arranging the target electric signals correspondingly generated by the photoelectric conversion units according to a third preset rule, thereby obtaining a target electric signal set.
Wherein, when the photoelectric conversion array includes n photoelectric conversion units, the target electrical signal set is n × 1-dimensional vectors; also, when n numbers of 1 to n are identified on the n photoelectric conversion units, the third preset rule may include the numbers or positions of the photoelectric conversion units.
Specifically, when it is determined that unknown light irradiates the photoelectric conversion array, each photoelectric conversion unit correspondingly generates an electrical signal, and the process of generating an electrical signal by each photoelectric conversion unit can also use the existing electrical signal acquisition method, for example, when the unknown light irradiates one photoelectric conversion unit in the photoelectric conversion array, 1 optical signal is generated, and then the 1 optical signal is respectively subjected to data selection processing, signal amplification processing and analog-to-digital conversion processing to obtain 1 electrical signal; the photoelectric energy conversion function of the photoelectric conversion unit itself may be used to generate 1 electrical signal, which is not limited in this regard.
Therefore, when the photoelectric conversion array includes n photoelectric conversion units, it is natural to generate n electric signals, and then set the n electric signals in different arrangements of the positions or numbers of the photoelectric conversion units as a target electric signal set.
According to the spectrum acquisition method with integrated spectrum resolution, the target electric signal set of the unknown light is acquired in a mode that the unknown light is irradiated to the photoelectric conversion array, so that light energy generated by the unknown light can be absorbed by the photoelectric conversion array, the luminous flux of the acquired target electric signal set is greatly increased, and the accuracy and the reliability of spectrum resolution are effectively improved. Furthermore, the energy supply property of the photoelectric conversion array is combined on the basis of increasing the luminous flux, so that the aim of self-energy supply or low-energy consumption operation can be fulfilled while spectrum reconstruction is carried out on the obtained target electric signal set, and the effects of low carbon and environmental protection can be achieved.
In the actual processing procedure, the acquiring procedure of step S130 may include:
and performing spectral reconstruction on the target electric signal set by using the target photoresponse curve set so as to obtain a target spectrum.
Specifically, since the target electrical signal set is n × 1-dimensional vectors and the target optical response curve set is n × m-dimensional matrices, the target optical response set may be used to perform spectral reconstruction on the target electrical signal set, and the reconstruction algorithm may be I ×n×1＝F(λ)×Rn×m(lambda). Wherein, In×1Representing a target electrical signal set, F (λ) representing a target spectrum, λ representing a wavelength of the unknown light, Rn×m(λ) represents a set of target light response curves. Further, when the number of the photoelectric conversion units in the photoelectric conversion array is different, the corresponding spectral resolution effect is also different, that is, fig. 5A is a full width at half maximum FWHM contrast diagram of the target spectrum when the number of the photoelectric conversion units in the photoelectric conversion array is different, and fig. 5B is a spectral resolution contrast diagram of the target spectrum when the number of the photoelectric conversion units in the photoelectric conversion array is different. As can be seen from fig. 5A and 5B, when the number of the photoelectric conversion units in the photoelectric conversion array is larger, the target spectrum of the finally obtained unknown light is closer to the true spectrum, and the effect of spectrum reconstruction is higher.
According to the spectrum acquisition method with integrated spectral resolution, the target spectrum of the unknown light is acquired by performing spectral reconstruction on the target electric signal set output when the unknown light irradiates the photoelectric conversion array through the target light response curve set output when the monochromatic light irradiates the photoelectric conversion array, so that the purpose of efficient spectral resolution of the unknown light is achieved.
It should be noted that, in order to make the whole process of the method of the present invention more clear and complete, the method of the present invention can be further described with reference to the general flow diagram shown in fig. 6, which includes the following processes:
when it is determined that unknown light irradiates the photoelectric conversion array, each photoelectric conversion unit correspondingly generates an electric signal, and after data selection processing, signal amplification processing and analog-to-digital conversion processing are respectively carried out on each generated electric signal, n electric signals are obtained and are respectively represented as I1、I2、…、InArranging the n electric signals according to n serial numbers of 1-n marked on the n photoelectric conversion units, thereby outputting a target electric signal set I of n-1 dimensional vectorn×1。
When the preset monochromatic light is determined to be irradiated on the photoelectric conversion array, m electric signals respectively generated by each photoelectric conversion unit are obtained, so that the aim of monochromatic light calibration is fulfilled; wherein, the m electric signals represent that each photoelectric conversion unit respectively generates electric signals corresponding to the m monochromatic lights one by one; then, after the m electric signals are arranged according to the different acquisition wave bands, acquisition time and corresponding monochromatic light, obtaining the light response curves respectively generated by each photoelectric conversion unit, namely obtaining n light response curves generated by the photoelectric conversion array; finally, arranging the n photoresponse curves according to the serial numbers or positions of the photoelectric conversion units to obtain a target photoelectric response curve set R of the n-x-m dimensional matrixn×m(lambda). Acquiring a target electrical signal set In×1And a target set of photoelectric response curves Rn×mThe process of (λ) may be performed separately or simultaneously, and is not particularly limited herein.
Further, according to a spectral reconstruction algorithm In×1＝F(λ)×Rn×m(λ), a target spectrum F (λ) of the unknown light is obtained. Wherein, In×1Representing a target electrical signal set, F (λ) representing a target spectrum, λ representing a wavelength of the unknown light, Rn×m(λ) represents a set of target light response curves.
