Description

Title: An infrared sensor unit, a method and a computer program product
The invention relates to an infrared sensor unit for performing an infrared measurement on an agricultural or horticultural sample, comprising an illumination unit for generating infrared light propagating towards the sample, and a spectrometer for sensing the generated infrared light after interaction with the sample.
Such infrared sensor units are known for performing infrared measurements on samples so that values of physical, chemical and/or biological parameters can be determined in a reliable and quick manner.
However, it appears in practice that a specific infrared sensor unit is merely applicable to a limited number of sample types, due to hmitations of the measurement range of the spectrometer.
It is an object of the invention to provide an infrared sensor according to the preamble that is applicable to a wider number of sample types. Thereto, according to an aspect of the invention, an infrared sensor unit according to the preamble is provided, wherein the illumination unit includes a control unit for tuning the amount of infrared light generated by the illumination unit.
By tuning the amount of infrared light generated by the illumination unit the amount of light sensed by the spectrometer can be set to fall within a measurement range of the spectrometer, thereby enabling a the infrared sensor unit to carry out an accurate measurement to a wide variety of sample types. Further, a wide variety of characteristics of the sample can thus be analyzed.
The invention is at least partly based on the insight that the amount of infrared light, after interaction with the sample, may be strongly dependent on the type of the sample. Then, by adjusting the infrared light energy, the infrared sensor unit is apt to perform measurements on samples having a relatively weak or a relatively strong response to the infrared signal interrogating the sample.
The invention also relates to a method.
Further, the invention relates to a computer program product. A computer program product may comprise a set of computer executable instructions stored on a data carrier, such as a flash memory, a CD or a DVD. The set of computer executable instructions, which allow a programmable computer to carry out the method as defined above, may also be available for downloading from a remote server, for example via the Internet, e.g. as an app.
Other advantageous embodiments according to the invention are described in the following claims.
By way of example only, embodiments of the present invention will now be described with reference to the accompanying figures in which
Fig. la shows a cross sectional schematic side view of an infrared sensor unit according to the invention;
Fig. lb shows a schematic bottom view of the unit of Fig. la;
Fig. 2 shows a diagram illustrating levels of generated infrared light, and
Fig. 3 shows a flow chart of an embodiment of a method according to the invention.
The figures merely illustrate a preferred embodiment according to the invention. In the figures, the same reference numbers refer to equal or corresponding parts.
Figure la shows a cross sectional schematic side view of an infrared sensor unit 1 according to the invention, while Figure lb shows a schematic bottom view of the unit 1. The unit 1 is arranged for performing an infrared measurement on an agricultural or horticultural sample 2.
The infrared sensor unit 1 has a number of components including an illumination unit and a spectrometer 11. Further, the infrared sensor unit 1 includes a collimator 4 and a fiber 6a interconnecting the collimator 4 to the spectrometer 11. The illumination unit is provided with a multiple number of infrared illuminator elements 3a-f for generating infrared light propagating towards the sample 2. After interaction with the sample 2, the infrared light is received by the collimator 4, forwarded via the fiber 6a to the spectrometer, and sensed by the spectrometer 11, i.e. converted into an electronic signal representative of the sensed infrared fight.
The illumination unit also includes a control unit 5 for tuning the amount of infrared fight generated by the illumination unit. The control unit 5 is connected to the individual infrared illuminator elements 3a-f via control fines 5a-f. Further, the infrared sensor unit 1 is provided with a communication unit 10 connected to the spectrometer 11 via a data fine 6b, such as a serial digital data channel, for communicating the sensed data with other devices. In addition, the infrared sensor unit 1 includes a processor unit 7 for controlling the operation of the sensor unit 1.
The infrared sensor unit 1 includes a housing 8 for accommodating the components therein or thereon, e.g. functioning as a handheld device.
During operation, the amount of infrared fight that is generated by the illumination unit can be tuned thereby indirectly tuning the amount of infrared fight that is sensed by the spectrometer 11. By setting the amount of sensed infrared fight, the measurement range of the spectrometer 11 can effectively be exploited. If the amount of infrared fight is relatively high after interaction with the sample, the infrared fight level of the illumination unit can be set relatively low thereby counteracting that the spectrometer 11 is over exposed. On the other hand, if the amount of infrared fight is relatively low after interaction with the sample, the infrared fight level of the illumination unit can be set relatively high thereby facilitating that the spectrometer 11 senses a signal having an energy level that is sufficiently high above a sensitivity level of the spectrometer 11. Then, the amount of infrared fight sensed by the spectrometer 11 is within a measurement range of the spectrometer 11.
Preferably, the control unit 5 is arranged for switching the amount of infrared fight between a pre-defined multiple number of discrete infrared fight levels. As an example, the amount of infrared fight can be selected from three, five or ten discrete levels, including a level wherein no fight is generated. Alternatively, the amount of infrared fight can be set in a continuous range.
In a very advantageous embodiment, the amount of infrared fight is adjusted to a pre-defined level that is associated with a selected agricultural or horticultural sample class. Then, the amount of infrared fight can be set to a level that is pre-programmed in association with a particular sample class. As an example, different sample types can each be associated with a respective amount of infrared fight to be generated by the illumination unit.
Fig. 2 shows a diagram illustrating levels of generated infrared fight. A vertical axis in the diagram denotes an intensity of infrared fight I generated by the illumination unit. Along a horizontal axis C in the diagram a number of sample classes Ci, C2, C3 are shown. Each of the sample classes is related to a specific type of agricultural or horticultural sample such as sand, grass or corn. Further, each of the sample classes Ci, C2, C3 is related to a pre-defined discrete infrared fight level I\, h, /3.Then, each sample class may be coupled to a unique amount of infrared fight to be generated by the illumination unit.
During operation of an advantageous embodiment of the unit 1 an agricultural or horticultural sample class C is selected, preferably by entering commands in a user-interface of the infrared sensor unit 1. Then, the control unit tunes the amount of infrared fight by adjusting the amount of light to a pre-defined level h, h, Is associated with the selected agricultural or horticultural sample class Ci, C2, Cs.
It is noted that the step of selecting an agricultural or horticultural sample class C can in principle be executed in another way, e.g. automatically or semi-automatically including a step of performing an automated classifying step, e.g. based on an image taken by a camera.
Optionally, the infrared sensor unit 1 is provided with a user interface arranged to receive user-specified instructions regarding the sample to be analyzed. As an example, the user may select a specific sample type from a pre-programmed list of sample types, each associated with a specific amount of infrared light to be generated. In principle, the list can be defined or extended by the user, e.g. based on actual test data. Alternatively or additionally, the infrared sensor unit 1 can be provided with a sensor for determining the sample type so that the amount of infrared light is adjusted automatically, depending on the outcome of the determined sample type, even without a user interaction.
In a specific embodiment, the control unit 5 is arranged for varying the amount of infrared hght of a subset of infrared illuminator elements 3 for tuning the overall amount of infrared hght generated by ah infrared illuminator elements 3. Applying this principle to the infrared sensor unit 1 as shown in Fig. 1, the subset of infrared illuminator elements 3 may include three elements generating a variable amount of infrared hght, while another three elements generate a fixed amount of infrared hght. However, also another distribution of illuminator elements 3 generating a variable and fixed amount of hght, respectively, can be apphed, e.g. four elements generating a variable amount of infrared hght and two elements generating a fixed amount of infrared hght.
In the shown embodiment, the spectrometer 11 is surrounded by the multiple number of infrared illuminator elements 3a-f to obtain a focused infrared hght beam on the sample 2. Further, the illuminator elements 3a-f are mainly evenly distributed in a circumferential direction C relative to the spectrometer 11 to obtain a more or less evenly distributed infrared light beam on the sample 2. Alternative arrangements of the infrared illuminator elements can be implemented, e.g. by arranging the infrared illuminator elements in a one-dimensional or two-dimensional array.
Further, in the shown embodiment, the infrared illuminator elements 3 and the spectrometer 11 are arranged in or on a dome-shaped bottom surface 9 of the infrared sensor unit 1 to optimize enlightening conditions on the sample 2. In another embodiment, the infrared illuminator elements 3 and the spectrometer 11 are arranged in another geometry, e.g. a plane surface.
It is noted that the geometry of the infrared sensor unit, especially regarding ihuminating aspects of the illumination unit, such as the dome shaped bottom surface of the infrared sensor unit and the arrangement of ihuminator elements on a circumscribing contour around the spectrometer, preferably evenly distributed, can not only be apphed to the infrared sensor unit as defined in claim 1, but also more generally to an infrared sensor unit for performing an infrared measurement on an agricultural or horticultural sample, comprising an illumination unit for generating infrared light propagating towards the sample, and a spectrometer for sensing the generated infrared light after interaction with the sample.
The infrared light propagates from the individual infrared illuminator elements 3 as transmission beams Τι, T2 towards the sample 2. After interaction with the sample 2, a reflection infrared light beam R propagates towards the spectrometer 11 of the infrared sensor unit 1. Here, the spectrometer 11 is of a diffused reflection type. Alternatively, the infrared sensor unit 1 is arranged for performing a transmission type infrared measurement. Further, a single number or a multiple number of spectrometer 11 is applied, e.g. for analyzing distinct spectra of the sensed light beam.
Advantageously, the illuminator unit includes a near infrared NIR and/or a mid infrared MIR illuminator element. Further, illuminator unit may include illuminator elements that are mutually identical or nearly identical. However, the infrared illuminator elements may also be different, e.g. including a first set of NIR illuminator elements and a second set of MIR illuminator elements or a single NIR or MIR illuminator element. In addition, the illuminator unit may include a visible light illuminator element such as a laser unit, e.g. for performing a raman spectroscopy measurement, and/or a source generating an X-ray beam, e.g. for performing an X-ray fluorescence measurement XRF. In principle, any source generating a beam of the electromagnetic spectrum might be included in the illuminator unit.
Upon sensing the infrared signal, after interaction with the sample 2, the spectrometer 11 generates a sensor signal. Controlled by the processor 7, the sensor signal can be transmitted via the communication unit 6 as a data signal Si to a further device, e.g. for further analysis. Optionally, the sensor unit 1 may receive, via the communication unit 6, a response signal S2, e.g. including a conformation message and/or feedback information. The data signal Si and/or S2 can be transmitted using a wired or a wireless channel.
Figure 3 shows a flow chart of an embodiment of a method according to the invention. The method is used for performing an infrared measurement on an agricultural or horticultural sample such as plants e.g. as grass or corn, or soil. The method comprises a step of providing 110 an infrared sensor unit 1 according to any of the claims 1-10, and a step of tuning 120 the amount of infrared fight generated by the illumination unit such that an amount of infrared fight sensed by the spectrometer 11 is within a measurement range of the spectrometer.
The method of performing an infrared measurement can be facilitated using dedicated hardware structures, such as computer servers. Otherwise, the method can also at least partially be performed using a computer program product comprising instructions for causing a processor of a computer system or a control unit to perform a process including at least one of the method steps defined above. All (sub)steps can in principle be performed on a single processor. However, it is noted that at least one step can be performed on a separate processor. A processor can be loaded with a specific software module. Dedicated software modules can be provided, e.g. from the Internet.
The invention is not restricted to the embodiments described herein. It will be understood that many variants are possible.
In principle, also another number of infrared illuminator elements can be applied, e.g. four or ten infrared illuminator elements. Alternatively, a single infrared illuminator element can be applied, the element being controlled so as to tune the amount of generated infrared light.
In order to operate properly, the infrared sensor unit may function as an autonomous device including additional components such as a power supply, or as a supplementary device operating in concert with another device such as a mobile electronic communication device.
In addition, the illumination unit may be calibrated, preferably periodically, e.g. using a calibration reflection measurement. Then, the amount of infrared light that is generated by the illumination unit can accurately be set.
Further, the infrared sensor unit can be applied for measuring physical, chemical and/or biological parameters for analysing agricultural and/or horticultural sample types or other sample types, including plastic material, oil and/or gas, pharmaceutical substances and biomaterial, e.g. in health care applications.
These and other embodiments will be apparent for the person skilled in the art and are considered to fall within the scope of the invention as defined in the following claims. For the purpose of clarity and a concise description features are described herein as part of the same or separate embodiments. However, it will be appreciated that the scope of the invention may include embodiments having combinations of all or some of the features described.
