> The team demonstrated that this intensity interferometer can image millimeter-wide letters at a distance of 1.36 km

1mm at 1.36 km works out to about 150 milliarcsec (mas), if you're used to those units from astronomy contexts.
Letters were 8 mm.

> To demonstrate the system’s capabilities, the team created a series of 8-mm-wide targets, each made from a reflective material and imprinted with a letter.

I checked the paper, by "8mm wide" they mean that the letters were 8mm tall, which is a 22pt font (name-tag size), for those curious.
i'm a bit confused when they don't measure things in olympic pools and bananas for scale
intensity interferometer means it interferometers intensity of light.

imaging technologies you mistook for imagination technologies and their gpu inside of a sega dreamcast or iphone, ipad,...

1.36 km = 0.85 miles
