Description

Technical Field

[0001] This utility model relates to the field of spectral detection device technology, specifically to a quaternary array multispectral detection device. Background Technology

[0002] With the rapid development of science and technology, multispectral technology has gradually shown its unique advantages in the fields of ambient light detection and material identification. Traditional spectral detection devices are mostly based on a single spectral band for signal acquisition, while multispectral detection devices can acquire information from multiple spectral bands at the same time, providing a richer data source for accurate color reproduction and material identification.

[0003] In multispectral detection technology, a common approach is to perform photoelectric conversion based on a standard imaging photonic detector structure to generate current, and then quantize the current signal through an analog-to-digital converter to obtain spectral information. The silicon surface of each IPD is usually coated with an interference filter, and the number and thickness of the film system are designed and manufactured according to the designed bandpass spectrum to ultimately form a multispectral detector. However, this traditional multispectral detection device has drawbacks in practical applications, such as poor performance in low-light environments.

[0004] To address these issues, a quaternary array multispectral detector is a promising solution. By employing detector arrays with four different spectral bands, this device can simultaneously acquire information from four spectral bands, achieving high spectral resolution and signal capture across multiple spectral bands, thereby providing more comprehensive and accurate spectral data.

[0005] However, in practical applications, the increased number of detector elements in this type of quaternary array multispectral detector leads to increased heat dissipation. Most devices employ fans for cooling, but fans rely primarily on airflow, and rapid airflow can negatively impact the transmitted spectral bands within the detector, affecting the accuracy of the detection data and hindering the achievement of effective static heat dissipation. Therefore, we propose a quaternary array multispectral detector. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a four-element array multispectral detection device, including a base plate 1 and a four-element photodetector 11 fixedly mounted on the base plate 1. A protective cover 2 is fixedly mounted on the upper surface of the base plate 1. A support box 3 is provided on one side of the protective cover 2. Two symmetrical fans 32 are fixedly mounted on the inner wall of the support box 3. A first serpentine tube 33 is fixedly mounted inside the support box 3, located above the fans 32. A micro pump 34 is fixedly mounted at one end of the first serpentine tube 33, and a water outlet pipe 341 is fixedly mounted at the outlet end of the micro pump 34. The other ends of the outlet pipe 341 and the first serpentine pipe 33 are both fixedly installed with hoses 35. The ends of the two hoses 35 are respectively fixedly installed with a delivery pipe 36 and a return pipe 37. The ends of the delivery pipe 36 and the return pipe 37 are both fixedly installed with second serpentine pipes 38. The two second serpentine pipes 38 are interconnected. The second serpentine pipes 38 are located inside the protective cover 2 to ensure that the micro pump 34 can work during use to transport the cooling medium in the pipe. After the cooling medium is transported into the second serpentine pipe 38, it can achieve the effect of heat dissipation inside the protective cover 2.

[0031] In this embodiment, the bottom and top of the protective cover 2 are connected to the outside, and multiple air inlets 30 connected to the outside are provided on the side of the protective cover 2 to realize air circulation operation.

[0032] Specifically, multiple support legs 31 arranged in a matrix are fixedly installed on the bottom surface of the protective cover 2. The height of the support legs 31 is greater than 8cm, so that the support legs 31 can be used for support operation.

[0033] Furthermore, a fixed base plate 20 is fixedly installed at the bottom of the protective cover 2. The fixed base plate 20 is fixedly installed on the upper surface of the base plate 1 by multiple fastening screws, which facilitates the fixed installation operation. The side plate of the protective cover 2 is provided with wire-passing holes for wire-passing operation, so that wiring operation can be carried out normally.

[0034] In addition, multiple heat sinks 21 arranged linearly and at equal intervals are fixedly installed on the top surface of the protective cover 2. The distance between two adjacent heat sinks 21 is between 0.8cm and 1.5cm, so as to realize heat dissipation operation by using the heat sinks 21.

[0035] It is worth noting that a fixing strip 22 is fixedly installed between each of the two adjacent heat sinks 21. A semi-circular groove 221 is provided on the upper surface of the fixing strip 22. The cross-section of the semi-circular groove 221 is semi-circular. The number of heat sinks 21 is 15 to 24, which makes it easier to clean the dust in the semi-circular groove 221 and avoids the existence of dead corners that affect the dust cleaning effect.

[0036] It is worth noting that a beam splitting module 10 is fixedly installed on the base plate 1, and multiple detector units 12 are set on the quaternary photodetector 11. A signal processing module 13 is also fixedly installed on the base plate 1. The multiple detector units 12 adopt a series array design. Each detector unit 12 can respond to signals of different spectral bands. The beam splitting module 10 divides the incident light into multiple spectral bands according to wavelength and supplies them to different detector units 12 in the quaternary photodetector 11 respectively. The signal processing module 13 is used to receive the signals output by the detector units 12, amplify, filter and digitize them, and finally output multispectral data. Through the series array design of the quaternary detector units 12, high spectral resolution is achieved, which can accurately distinguish signals of different spectral bands.

[0037] Finally, it should be noted that the components involved in this utility model, such as the beam splitting module 10, detector unit 12, quaternary photodetector 11, and signal processing module 13, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0038] In use, the four-element array multispectral detection device of this utility model is installed by fixing the base plate 20 to the upper surface of the base plate 1 with fastening screws before wiring. In addition, the micro pump 34 is connected to an external power source and made to work. The micro pump 34 works to transport the cooling medium in the first serpentine tube 33 and the second serpentine tube 38. The cooling medium in the second serpentine tube 38 can exchange heat with the protective cover 2 to cool down the protective cover 2. The fan 32 is connected to an external power source and made to work. The fan 32 works to dissipate heat from the first serpentine tube 33, so that the cooling medium in the first serpentine tube 33 can be reduced to a suitable temperature, realizing the operation of circulating and static heat dissipation.
