Embodiment 1

[0031] Such as figure 1 As shown, an adaptive imaging method for improving computational ghost imaging efficiency includes the following steps:

[0032] Step 1. Configure the initialization parameters of the computing ghost imaging system, that is, set the coordinates of the starting point of imaging (x 1 ,y 1 )=(0,0), imaging resolution parameter value m 1 ×n 1 =4×4, binning parameter value b 1 =2. It can also be manually set to other values ​​with prior knowledge.

[0033] Step 2: The spatial light modulator that modulates the light source loads the initialization parameters of the ghost imaging system, and performs the i-th ghost imaging target image sampling, that is, uses the intensity correlation algorithm to combine the total light intensity information collected by the ghost imaging system with the two-dimensional data of the same light source. The light intensity distribution information is calculated, and after M operations, the image information containing the...

Abstract

The invention relates to an adaptive imaging method used for improving the ghost imaging efficiency, and belongs to the technical field of optical imaging. The object of the invention is to provide an adaptive imaging method used for improving the ghost imaging efficiency in order to solve the problem that in the practical application of the ghost imaging technology, the imaging efficiency is low since the resolution is a fixed value and cannot be adaptively adjusted according to different conditions. According to the method, during the application of the ghost imaging technology, the resolution can be adaptively adjusted by employing a pixel combination mode according to the practical application condition requirement, and the ghost imaging efficiency is improved; besides, the method can be applicable to a calculation ghost imaging system and a classic ghost imaging system, an extra mechanism is not needed, and the universality is high.

Description

technical field [0001] The invention relates to an adaptive imaging method for improving ghost imaging efficiency, and belongs to the technical field of optical imaging. Background technique [0002] Ghost imaging technology is a new imaging technology developed in the past ten years. This technology is based on the intensity correlation algorithm and indirectly images the target with the help of the detection arm and the reference arm. Among them, the detection arm is a point detector, and the reference arm is a high-resolution array detector. During imaging, neither the detection arm nor the reference arm can directly image the target, but the target information can be indirectly obtained after the signals of the two arms are subjected to the second-order cross-correlation operation. Compared with the traditional photoelectric imaging technology based on optical system, ghost imaging technology has potential applications in the fields of biomedicine, industrial measuremen...
