Ghost Imaging System Based On Spatial Light Modulator

Product Briefing

The system mainly consists of a ghost imaging hardware device and correlation computing software. SLM-based ghost imaging system mainly uses SLM instead of rotating hair glass sheet to get the pseudo-thermal light field, which is propagated through two different light paths, one of which is a signal beam through the target object; the other is called the reference beam, which is propagated freely through the space, and then detected by the CCD for the light intensity-conventional ghost imaging (or theoretical simulation calculation); the software correlates the total light intensity information of the signal beam and the reference beam, and then the image of the target object can be reconstructed. The other beam is called the reference beam, after free propagation in space, the light intensity is detected by the CCD - traditional ghost imaging (or theoretical simulation calculation to obtain - calculation of scattering imaging); through the software will be the signal beam and the reference beam of the total light intensity information for correlation calculations, can be reconstructed to get the target object image.

System Function

● Traditional Ghost Imaging Module: the atlas of pseudo-thermal light field can be simulated and loaded into SLM; the signals of APD detector and CCD are acquired through programmed synchronization, and finally the image of the object is calculated through the correlation algorithm.

● Calculation of ghost imaging module: simulate the calculation of pseudo-thermal light field atlas and loaded into the SLM; through the programmed synchronization to obtain the APD detector and the theoretical calculation of the corresponding atlas reference signal, and finally through the correlation algorithm to calculate the image of the object.

● Theoretical simulation module: the reference signal and object signal can be simulated and calculated, and then the image of the object can be calculated through the optical association algorithm.
