Description

Technical Field

[0001] The utility model relates to the technical field of optical array probe accessories, and more specifically to a calibration bracket suitable for a two-dimensional stereoscopic imaging optical array probe. Background Art

[0002] The 2D-S optical imaging array probe (2D-S) is developed and produced by SPEC, USA. It consists of two 128 photodiode linear arrays working independently as a high-speed, high-resolution optical imaging probe. It can capture a 2D image of particles that pass through the sample volume where the laser beams overlap. And the area where the beams overlap uniquely defines the depth of field (and sample volume) of small particles. It can image particles as small as 10 microns at a speed of 200 meters per second. It greatly improves the determination of sample volume and small particles less than 100 microns.

[0003] As a precision detection device, the 2D-S probe needs to be maintained every three months. In order to ensure the accuracy of the 2D-S measurement results, it needs to be calibrated regularly. Simple calibration is performed every six months, and a comprehensive calibration is required once a year.

[0004] During the calibration process, simulated particles of standard size are needed to simulate real water droplets or ice crystals of different particle sizes, so as to calibrate the 2D-S's judgment standard for particle size. The 2D-S instrument needs to maintain a stable position and posture during long-term continuous observation to obtain accurate measurement results. When calibrating standard particles, some slight shaking or movement may cause measurement errors, so the role of the calibration bracket is very important.

[0005] The research on calibration brackets can provide a stable support structure to prevent the instrument from shaking or moving during the measurement process, and can also resist the influence of external environmental factors. By developing a special calibration bracket suitable for 2D-S equipment, it can help reduce or eliminate measurement errors caused by the equipment or the operator itself, improve calibration efficiency and the reliability of measurement results, thereby ensuring the reliability of long-term measurement data of 2D-S during use.

[0006] Therefore, how to provide a stable support structure to prevent the instrument from shaking or moving during the measurement process and resist the influence of external environmental factors for a calibration bracket suitable for a two-dimensional stereoscopic imaging optical array probe is an urgent problem to be solved by technical personnel in this field.

[0023] Please refer to the attached Figure 1-6 , disclosed in the utility model, is a calibration bracket suitable for a two-dimensional stereoscopic imaging optical array probe.

[0024] The utility model,

[0025] Working principle:

[0026] The standard particle calibration bracket is installed and fixed. The bracket 1 uses two half-cross mounting plates to be fixed on the two-dimensional imaging light array probe (2D-S) with bolts to form a stable base structure. The support frame 2 composed of a double-pillar structure is used to stably install the adjustment plate 3. The long slot hole 31 on the adjustment plate 3 is used for fine-tuning the mechanism. The bottom end of the copper tube 4 extends to a position about 2mm from the center point of the two 128 photodiode 5 linear arrays. The standard particle ball is released through the copper tube 4 and passes through the diode array. The two-dimensional imaging light array probe (2D-S) captures the two-dimensional image of the particles passing through the sample volume where the laser beam overlaps for calibration.

[0027] Assembly of mounting bracket 1

[0028] The fixing frame 1 consists of two half-cross mounting plates. These two mounting plates are fixed to the upper part of the 2D-S device by bolt connection to form a stable base structure. This design ensures the stability and reliability of the entire calibration device.

[0029] Installation of support frame 2 and adjustment plate 3:

[0030] The support frame 2 adopts a double-pillar structure, which is fixed to the mounting bracket 1 by bolts or other fasteners. The design of the support frame 2 allows the mounting adjustment plate 3 to be firmly mounted thereon. The mounting adjustment plate 3 is provided with long slots 31, which allow the user to fine-tune the position of the copper tube 4 to ensure that the standard particle ball can accurately pass through the center point of the two 128 photodiode 5 linear arrays.

[0031] Installation and function of copper tube 4:

[0032] The bottom end of the copper tube 4 extends to a position about 2 mm from the center point of the two linear arrays of 128 photodiodes 5. The copper tube 4 is designed so that the standard particle ball can be released through the copper tube 4 and pass through the diode array.

[0033] When the standard particle ball passes through the diode array, the 2D-S device can capture a two-dimensional image of the particles that pass through the sample volume where the laser beam overlaps, thereby performing calibration. This can significantly improve the calibration accuracy of the 2D-S device and ensure the reliability of the measurement results.

[0034] Calibration process:

[0035] During the calibration process, first fix the calibration device to the 2D-S device, making sure all parts are firmly installed.

[0036] By adjusting the long slot hole 31 on the mounting adjustment plate 3, the position of the copper tube is adjusted so that the standard particle ball can accurately pass through the center point of the diode array.

[0037] The standard particle beads are released and the 2D-S device captures their two-dimensional images. By analyzing these images, the 2D-S device can be accurately calibrated.
