Kuusela https://research.utu.fi/converis/portal/detail/Publication/32053938?lang=en_GB (published in AJP) (PDF here) describes a pseudothermal light source that can be built easily in college labs, and can be used to do some quantum correlation experiments. They propose this as an alternative to the popular design based on a laser bouncing off a rotating ground glass surface, as originally described by Martiensen.
They use a bandlimited noise source to modulate the intensity of light from an ordinary LED. This gives the opportunity to study temporal photon statistics, but not spatial.
Is it possible in principle to do this (not necessarily in a college setting) with electrons or other particles, by modulating the beam (similar to modulating spot intensity in an old-style TV tube)? Would this allow the nature of second-order quantum correlations to be studied?
Edit #2: If we use an actual TV or oscilloscope tube, can we record the light intensity of the spot on the screen and use it to indirectly study electron antibunching via temporal correlation?
Edit #3: If we use a color TV tube and apply different noise modulations to each beam, can we study spatial antibunching?
