What is the *DETECTOR* in the double slit experiment and how
I thought you were asking about the detector downstream of the double slit, where the interference pattern is visible; every practical double-slit experiment includes such a detector. But instead, you are asking about a hypothetical detector which could “tag” a particle as having gone through one slit or the other. Most interference experiments.
Light from a green laser passing through two slits 0.4mm wide and 0.1mm apart In modern physics, the double-slit experiment demonstrates that light and matter can satisfy the seemingly-incongruous classical definitions for both waves and particles, which is considered evidence for the fundamentally probabilistic nature of quantum mechanics.

Quantum Mechanics and the Famous Double
If a light detector is used to measure which slit each photon passes through then the interference pattern (shown in Figures 2d and 3b) is replaced by a diffraction envelope (shown in Figure 3a), as if the light consists of two streams of particles which spread out and merge over time.
Physics in a minute: The double slit experiment
One of the most famous experiments in physics is the double slit experiment. It demonstrates, with unparalleled strangeness, that little particles of matter have something of a wave about them, and suggests that the very act of observing a particle has a dramatic effect on its behaviour. To start off, imagine a wall with two slits in it.
Doubleslit Interference Experiment : 5 Steps
Step 2: Find the Diffraction Pattern. With your two-slit grating set up, you want to see that it works, and determine the optimal positions for your photon source and detector. Put a white screen (a piece of paper or business card) about 20 inches (50 cm) behind the grating, and a laser pointer a few inches in front of it.
Quantum double-double-slit experiment consists of two double-slits and a source of photon pairs. In this experimental situation, a single photon passes through each double-slit and detected.
We send single photons through a birefringent double-slit apparatus and use a linear array of single-photon detectors to observe the developing interference pattern. The analysis of the buildup.
Disentangling the waveparticle duality in the double
The entanglement enabled them to determine which opening the photon went through, but a detector on the other side still picked up an interference pattern, demonstrating light’s wave- and particle.
Thomas Young's Double Slit Experiment
There are two possible results of this experiment: Particle interpretation: If light exists as particles, the intensity of both slits will be the sum of the intensity from the individual slits.
