Zeiss announces holographic camera that turns any window into an invisible camera: It sounds like they are targeting consumer applications, so high quality photography may not be...

It sounds like they are targeting consumer applications, so high quality photography may not be impacted soon, but this is really wild:

Just what we need, more stuff to watch us in more places.......
On the other hand, technical progress waits for no one, and I suppose it has big implications for things like security, and 'convenience'.
Our issue seems to be that it takes more time for expertise, mastery and judgement to develop than it does to make the thing we just mastered obsolete.

The article didn't present any useful information on just how it works. I get the impression that it's not just any window they use, but more likely a piece of glass that has some particular characteristics (not described) and attached to a 'hidden sensor'. So it's not that our windows will suddenly become cameras unless someone sneaks in and replaces them with the special glass.

Or did I miss something?

That's my take, exactly.

Exactly......

What mysteries lurk in the hearts of men? Only the Shadow Knows.... Old intro line of a Radio Program... Now what mysteries lurk in the Holograms of Zeiss, we will learn more in the future... for now I move to another topic found while searching for this topic... new reading, Holograms underwater:

You didn't miss much, the article is very light on details, but I'm sure we're going to be hearing more soon. They describe a hidden sensor that captures the images and it sounds like the glass is not ordinary glass, but special glass with some kind of transparent waveguide. They do mention that it is very wide aperture.

A hologram is a three-dimensional (3D) image formed by the interference of light beams, typically produced by using a laser and a photosensitive material. It is created by recording the diffraction pattern of light waves reflected from or transmitted through an object. Holograms appear to be 3D images that can be viewed from different angles, providing a sense of depth and realism to the image.

Unless its a clickbait fake news article misusing the term hologram, they are likely using a laser to scan the special glass and recording the subsequent interference pattern. With what understanding I have of physics, this is certainly feasible and not only would be useful as a camera, but also as a holographic display.

I have a ton of respect for Zeiss and if anybody can make glass that does this, they would be among them.

Time to invest in Zeiss Lens Wipes, grin. . . .
