It is certainly easier (Gaussian curvature blah blah blah).<br /><br />If so, doesn't that eliminate most of the advantage? It might make more sense for a widescreen panoramic sensor.Viaddhttps://www.blogger.com/profile/05455283796086963452noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-66264751177350087562020-12-14T18:39:11.027+02:002020-12-14T18:39:11.027+02:00In the web it shows a convex design, but all the t...In the web it shows a convex design, but all the times i have read about curved ensor was speaking about concave. the image looks concave also (but this could be an optical effect. any info about this?rgutalvhttps://www.blogger.com/profile/08967120929602206383noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-57152936889670417742020-12-14T13:31:18.677+02:002020-12-14T13:31:18.677+02:00Hi,

Or do you have collaboration with certain sensor manufacturers to get unpackaged sensors? If yes it would be interesting to know what options are there.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-61305017762416269242020-12-14T12:46:37.636+02:002020-12-14T12:46:37.636+02:00I remember on trade shows coming across early prot...I remember on trade shows coming across early prototypes of this tech, where they would mainly demo this sensor with a more industrial application example. A comparison with an off-the-shelf camera and lens combination showed the advantage of having much smaller and simpler optics with a curved sensor. <br /><br />In this announcement, it seems they have pivoted more towards space and observatory applications? I wonder if this is due to the smaller volume and less cost sensitive requirements of this market. I hope cost and scalability issues can be overcome if there are any, as this is really cool technology.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-82472180937380769162020-12-14T11:01:56.182+02:002020-12-14T11:01:56.182+02:00Hi, you are right, we take available sensors and j...Hi, you are right, we take available sensors and just change their shape before packaging.

The contact form on their website today says 'error please try again later'. Lets see when they are really ready to sell a product. I dont know... but with such topics around "breakthrough technology by research institutes" i sometimes get the impression that the announcements and real availability are a bit 2 different worlds. I thought of this again with the imec <2u/pix swir thin film sensor announcement a few days back. Again slides with single digit dollar cost (that gets announced for years now). But we are still in the x1000$ world and will be there for some years in my opinion - also CQD sensors that are available today are expensive, large etc. <br />I doubt we will actually be able to solder a working curved sensor to a PCB soon in the context of a camera that gets then deployed into a 24/7 robotic application in 100s or 1000s / year - but will be happy if curv-one proves me wrong.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-21632128522848801612020-12-14T07:38:28.076+02:002020-12-14T07:38:28.076+02:00They dont state this on their website, or I did no...They dont state this on their website, or I did not see it in the first moment - but the sensor itself is a standard sensor, right? The parameters and foto look very similar to CMV12000, right? So they dont develop a full sensor or adapt a sensor design to something they can then make spherical - but they take a available commercial sensor and somehow change it to a spherical sensor?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-52975371525199249712020-12-13T23:36:04.730+02:002020-12-13T23:36:04.730+02:00Nice achievement !
