Description
Ghost imaging is an imaging technique that aims to reconstruct the spatial information of an object by studying the intensity correlations between two beams originating from the same source, where the object is placed only in one of the beams.
In this work, we investigate ghost imaging using pseudo-thermal light generated by passing a He-Ne laser beam through a rotating ground-glass diffuser. The generated light is divided into reference and object arms using a beam splitter. Spatial intensity patterns are recorded using a camera in the reference arm, while the light transmitted through a single-slit object in the object arm is measured using a bucket detector. Synchronized measurements are analysed using intensity correlations to investigate image reconstruction. Preliminary studies on single-slit image reconstruction are underway, with a focus on optimising experimental parameters, including the number of acquired frames, to improve image quality.
