This video is recorded by an EMCCD camera at the single-photon level. The Figure consists of a few thousand photons (individual dots in the picture). The source is an attenuated HeNe laser and the double-slit is realized using an SLM. (Video credits: Lavanya Taneja and Rishabh Sahu)
This video is the classic Young double-slit experiment performed with single photons. The source is a highly attenuated HeNe laser and the interference is recorded using an EMCCD camera, at the rate of less than a photon per frame. (Video credits: Lavanya Taneja)
In this experiment, a photon is in the superposition state of having orbital angular momentum values of either +4ℏ or -4ℏ . The source is a highly attenuated HeNe laser and the interference is recorded using an EMCCD camera, at the rate of less than a photon per frame. (Video credits: Lavanya Taneja)
This is the far-field pattern of a laser beam reflecting off of a dynamic aperture. The dynamic aperture is realised using a spatial light modulator and the far field intensity is captured using a CCD camera. (Video credits: Rishabh Sahu)
