Description
技术领域technical field
本发明涉及水体中的浮游生物的成像检测领域，特别是涉及一种浮游生物成像检测装置。The invention relates to the field of imaging detection of plankton in a water body, in particular to an imaging detection device for plankton.
背景技术Background technique
当前，对浮游生物的检测方法一般是利用采样网收集浮游生物，带回实验室进行检测，但这样对浮游生物会产生一些不可避免的损伤。也有利用水样采集器将含有浮游生物的水样一起带回实验室进行检测，但采样工作量特别大。目前，一般的水下摄像机由于没有显微成像功能，所以，只能用于大型的水生生物进行成像。对于体形大小在1mm以下的浮游生物，一般需要显微放大才能对其进行成像检测，但显微镜的景深很小，不适合用于对在水体3维空间游动的浮游生物进行成像检测。At present, the detection method for plankton is generally to collect plankton by sampling net and bring it back to the laboratory for detection, but this will cause some inevitable damage to plankton. There are also water sample collectors used to bring back water samples containing plankton to the laboratory for testing, but the sampling workload is particularly heavy. At present, general underwater cameras can only be used for imaging large-scale aquatic organisms because they do not have a microscopic imaging function. For plankton whose body size is less than 1mm, microscopic magnification is generally required to image and detect them, but the depth of field of the microscope is very small, so it is not suitable for imaging and detecting plankton swimming in the three-dimensional space of the water body.
目前现有的技术是分别使用同轴数字全息或离轴数字全息对浮游生物进行成像检测。但由于同轴数字全息只适合于透明背景上的稀疏物体的成像，在水质比较浑浊的时候不能适用。离轴数字全息可以将物体的再现像与共轭像分离，但要求待测物体与图像传感器之间的距离较大，在不加光学放大透镜的情况下，系统的数值孔径较小，导致成像分辨率较低，若加入光学放大透镜，则会导致成像视场较小。可见，现有技术还不能解决对水质较浑浊条件下的浮游生物进行高分辨率的原位成像的问题。At present, the existing technology is to use on-axis digital holography or off-axis digital holography to image and detect plankton. However, coaxial digital holography is only suitable for the imaging of sparse objects on a transparent background, and cannot be applied when the water quality is relatively turbid. Off-axis digital holography can separate the reconstructed image of the object from the conjugate image, but requires a large distance between the object to be measured and the image sensor. Without an optical magnifying lens, the numerical aperture of the system is small, resulting in imaging resolution If the optical magnification lens is added, the imaging field of view will be smaller. It can be seen that the prior art cannot solve the problem of high-resolution in-situ imaging of plankton under the condition of relatively turbid water quality.

The picture record button 202 and the video record button 204 are used to operate and shoot a hologram or a hologram video. The control monitor 119 is also provided with a charging interface and an image and video export interface, the charging interface is used for charging the power battery 118 , and the image and video export interface is used for exporting pictures or videos taken by the color camera 107 .
使用时，利用承重缆绳将水下浮游生物成像检测装置投放到水中，通过控制监视器操作记录数字全息图或数字全息视频，导入计算机后通过再现程序利用双波长同轴离轴复合数字全息再现算法对全息图或视频进行再现，在程序中再现距离可以从Z1自动变化到Z2(Z1为彩色相机图像传感器到光学窗口2之间的距离，Z2为彩色相机图像传感器到光学窗口1之间的距离)，即可实现对成像检测区内的浮游生物进行成像检测。When in use, use the load-bearing cable to put the underwater plankton imaging detection device into the water, record the digital hologram or digital holographic video by controlling the monitor operation, import it into the computer and use the dual-wavelength coaxial off-axis composite digital holographic reproduction algorithm through the reproduction program For hologram or video reproduction, the reproduction distance can be changed automatically from Z1 to Z2 in the program (Z1 is the distance between the color camera image sensor and the optical window 2, Z2 is the distance between the color camera image sensor and the optical window 1 ), the imaging detection of plankton in the imaging detection area can be realized.
本发明基于双波长同轴离轴复合数字全息技术，采用从离轴数字全息图(Ioff)重建得到的图像传感器平面(Recordingplane)内物光波的低精度相位分布φoff作为同轴数字全息图(Iin)相位恢复迭代重建的初始相位分布，在待测物体(Object)平面内加入了从离轴数字全息图(Ioff)重建得到的物光波的低精度相位分布φ0-off作为同轴数字全息图(Iin)相位恢复迭代重建的约束条件。因此，本发明适合于水质比较浑浊或浮游生物(如藻类)浓度较高的情况下对水体中体型大小在10微米到1毫米范围内的浮游生物进行成像检测。而且，本发明具有较高的分辨率和较大的视场，具有检测效率高的特点。其分辨率大小约等彩色相机图像传感器的像素大小，成像视场等于图像传感器的感光面积。每拍摄一张全息图可检测的水体体积为V＝S*d，其中，S为图像传感器的感光面积，d为光学窗口1到光学窗口2之间的距离。The present invention is based on the dual-wavelength coaxial off-axis composite digital holography technology, and uses the low-precision phase distribution φoff of the object light wave in the image sensor plane (Recording plane) reconstructed from the off-axis digital hologram (Ioff) as the coaxial digital hologram (Iin ) phase recovery and iterative reconstruction of the initial phase distribution, adding the low-precision phase distribution φ0-off of the object light wave reconstructed from the off-axis digital hologram (Ioff) in the plane of the object to be measured (Object) as the coaxial digital hologram ( Iin) Constraints for iterative reconstruction of phase recovery. Therefore, the present invention is suitable for imaging detection of plankton in the water body with a body size ranging from 10 microns to 1 mm when the water quality is relatively turbid or the concentration of plankton (such as algae) is high. Moreover, the invention has higher resolution and larger field of view, and has the characteristics of high detection efficiency. Its resolution is about the same as the pixel size of a color camera image sensor, and the imaging field of view is equal to the photosensitive area of the image sensor. The volume of the water body that can be detected by taking a hologram is V=S*d, where S is the photosensitive area of the image sensor, and d is the distance between the optical window 1 and the optical window 2 .
