To take better images of atom clouds, one needs to use a lot of mirrors. This can be achieved various ways. One can build a spherical or cylindrical mirror or use multiple flat mirrors to create an imaging system that will focus the light from the atom cloud onto a camera.

Using multiple mirrors can be advantageous as it allows for more flexibility and control over the imaging system. For instance, by carefully arranging the mirrors, one can correct for aberrations, reduce stray light, and optimize the light collection efficiency. Additionally, multiple mirrors can be used to create multiple optical paths, allowing for simultaneous imaging from different angles or with different optical setups.

The choice of mirror type and arrangement will depend on the specific requirements of the imaging experiment and the available resources. Regardless of the approach, using mirrors is a key technique in obtaining high-quality images of atom clouds.
