摘要“鬼”成像( ghost imaging)又称双光子成像( two-photon imaging ) 或关联成像( correlated imaging) ,是采用双光子复合探测器恢复被测物体空间信息的一种新型成像技术。传统的光学观察是基于光场的强度的分布测量，关联光学则基于光场的强度的关联测量。并且传统的成像技术主要利用光场的一阶关联信息（强度与位相），而经典‘鬼’成像利用的光场的二阶关联（与强度波动的统计相关）。33017

在我们的生活中，经典热光源无处不在。用经典热光源实现的关联成像技术，具有更广泛、更实在的应用前景。本文通过应用LabView软件，模拟了经典热光场下的鬼成像过程。在仿真中，通过将相互独立的随机光叠加制造出非相干热光源，然后使非相干热光源通过分束器分成两路，此时，物体用 的空间分布矩阵表示，物体的空间分布信息被加载到信号光的相位上，通过两路光路的符合计数，可在另一路光路中可获得物体的像。数值仿真表明，随着采样分辨率的增加以及采样点数的增加，鬼成像的成像质量明显改善，其中采样点数的增加作用更加明显。

Title Labview based on the classic ghost imagingimitation heat source True research
Abstract
"Ghost" image (ghost imaging), also known as two-photon imaging (two-photon imaging) or correlated imaging (correlated imaging), is the use of two-photon detector complex restoration a new imaging technique the object spatial information. Traditional optical observations are distributed based on measuring the intensity of the light field, the associated optical correlation measurements are based on the intensity of the light field. And conventional imaging techniques using light field of a major order related information (intensity and phase), and the second-order correlation classic 'ghost' use of imaging light field (related to fluctuations in the intensity of statistics).
In our lives, the classic heat sources everywhere. With classic heat source to achieve relevance imaging technology, it has a broader, more realistic prospect. By application of LabView software, to simulate the classic ghost imaging process under hot light field. In the simulation, by the independent random light to create a non-coherent superposition of heat sources, thermal and non-coherent light source is pided into two by a beam splitter, this time, the object with a spatial distribution matrix representation of the space object distribution information is loaded into the phase of the signal light on the optical path through two coincidence counting, can be obtained in another way as the object light path. Numerical simulations show that with the increase of the resolution to increase sampling and sampling points, image quality ghost imaging significantly improved, increasing the number of sampling points where action is more obvious.
