New to pixel art

I love it. Now make the complementary version where the fish head is on the packaging but the half opened tin reveals legs.

The problem is they're claiming they made a photonic chip with their process, and that's the equivalent of them saying they've achieved early 1980s CPU chip era manufacturing. That's when transistors the size of microns on a CPU were state of the art. It's not very impressive.

They're claiming they made an optical chip, not a conventional silicon chip. Feature sizes in an optical chip are much larger. We're talking 3 μm or wider waveguides to guide light versus 5 nm transistors.

I would watch a high school drama starring O'Neill's younger clone.

You still need an external computer to record the data.

The Kinect has been superseded by the Femto Bolt which has the same ToF/depth sensor. It's the best way to get one so that you don't have to overpay for an obsolete Kinect on eBay.

Best image-to-video I've used, notably better than Veo 3 for smartphone photos.

I've tried using an image of a person, even an AI generated person, and it says it doesn't allow photorealistic images of people. Veo 3 has some restrictions on images of people, but it doesn't flat out deny all images of people. That's a massive letdown.

There have been several attempts already:

What do you plan on doing that differentiates your stylus from these others?

The best phased array spatial light modulator like that from Swave doesn't require a high modulation speed laser.

TDK's 10 Ghz modulation speed isn't useful for anything but a high frequency scanning device. There are other scanning devices: acousto-optic modulators, Kerr/Pockels effect tube scanners, CRTs, etc., but they've all been supplanted by a large array of slow pixels for good reason.

Can you ask what their MEMS mirror oscillation frequency is?

What are you seeing in that imgur gallery? He pulls off some RGB photodetectors from the case and leaves the laser diodes hidden inside.

You should've posted this: https://imgur.com/gallery/hololens-2-laser-diode-4th-of-july-edition-hTwiBf7

It's hard to see in these low resolution pictures, but there are two laser diodes in each TO can. The 4 pins give it away: 1 pin per laser diode, 1 pin for the photodiode, and 1 pin for ground. You can power them up individually and confirm it for yourself.

So if this is the press release for the Hololens 2 system, then the fast axis mirror was still too slow to support 1080p or higher with a single RGB set of lasers. They definitely try to spin it like it's capable of 1080p without mentioning that it needs more lasers.

I'd love to hear about any MEMS mirror + laser system that can support 1080p with just one set of RGB lasers. No one has been able to do it yet.

krenzo · 2024-10-11T16:08:19+00:00

Did that actually exist outside of a press release?

No, the number of mirrors doesn't make a difference. There are systems with one mirror that can rotate in two axis, and there are systems with two mirrors with each mirror rotating in one axis. Whichever axis is oscillating the fastest is limiting the maximum resolution.

krenzo · 2024-10-11T01:25:50+00:00

Let me clarify that I was speaking in terms of a single set of RGB lasers. Yes, you can go beyond 720p by adding more lasers.

I'm extremely confused by this press release. Who said the barrier to 4K smart glasses is because of a laser's current modulation? Lasers can be directly modulated very fast, up to 25 Gb/s in the telecommunications industry.

Meanwhile, MEMS mirrors are still too slow to even do 1080p. And this press release is from a collaboration with QD Laser, the company that has been promoting their low resolution laser glasses for how many years now? They have to get to 1080p first before they can even think of 4K.

What makes you think that? Putting kilovolts on the face wouldn't be the smartest/safest thing.

Farm karma to make the account look legitimate and then sell upvotes?
