Problems solved by technology
[0003] At present, the difficulty of the ghost imaging method based on intensity correlation imaging technology is that it is difficult to realize large field of view, high-resolution imaging and fast imaging at the same time.
When the traditional ghost imaging method increases the field of view or improves the resolution, it is mostly realized by increasing the amount of data, which will lead to a decrease in the imaging rate; on the contrary, when the traditional ghost imaging method increases the imaging rate, it is mostly realized by reducing the amount of data. The method of reducing the imaging field of view or reducing the resolution is often used

Embodiment 1
[0048] A ghost imaging method based on a bionic vision mechanism, the specific steps are as follows:
[0049] Step 1: Use the bucket detector to collect the total light intensity information of the reflected light after the light source irradiates the target; at the same time, use the bionic detector array to collect the two-dimensional light intensity distribution information of the same light source.
[0050] Step 2. Perform calculations based on the bionic vision mechanism to obtain the target shape:
[0051] Wherein, the bionic detector array includes a fixed-resolution area and a variable-resolution area composed of variable-resolution pixels.
[0052] The variable resolution pixel structure in the variable resolution area is: the inner diameter of the pixel is r i-1 , the outer diameter of the pixel is r i , the distance between the outer radius of the pixel and the inner radius of the pixel is h, and the arc length of the inner radius of the pixel is w i-1 , the oute...

Abstract
The invention relates to a ghost imaging method and a ghost imaging system based on a bionic vision mechanism, and belongs to the photoelectric imaging field. A laser source, a collimating lens, a rotary frosted glass, and a spectroscope are respectively disposed on the same optical path sequentially. The laser source, the collimating lens, and the rotary frosted glass are used to generate parallel pseu-dothermal light required by the ghost imaging. The spectroscope is used to divide the pseu-dothermal light into two optical paths, and reflection light is a reference arm optical path, and transmission light is a detection arm optical path. The light intensity distribution of the reference arm optical path is received by a bionic detector array, and pseu-dothermal light source two-dimensional light intensity distribution information is completed. After the light of the detection arm is irradiated on a target, the light is reflected, and then the light is reflected by the spectroscope, and the reflection light total light intensity is received by a barrel detector, and the target reflection light total light intensity information acquisition is completed. A related arithmetic unit is used for the operation of the information acquired by the bionic detector array and the barrel detector. The bionic variable resolution detector array is adopted, and large visual field, high resolution imaging and fast imaging are realized at the same time.
Description
technical field [0001] The invention relates to a ghost imaging method and system based on a bionic vision mechanism, belonging to the field of photoelectric imaging. Background technique [0002] With the continuous improvement of computer processing speed, compared with traditional photoelectric imaging technology, computational imaging technology is more and more widely used because of its low requirements for optical imaging devices, super-resolution imaging, and no environmental influence. Among them, based on intensity correlation imaging, that is, the ghost imaging method is a new photoelectric imaging method. This method is a system in which the target is imaged indirectly by means of a detection arm and a reference arm. The detection arm is a point detector, and the reference arm uses an array detector, and most of them use a (high-resolution) array detector. Because the detection arm containing a single-point detector can only obtain single-point intensity informa...
