For those in the northern hemisphere, summer is rapidly approaching, especially for those with kids. Camps, educational programs, and other activities are enrolling now, in advance of the long summer vacation. (Particularly long for Americans!) Aside from conventional sleepaway options for kids, there are science and technology courses, space camps, survival adventures, and more. Whatever your age, and whether on your own or as part of a formal group, do you have any specific learning activities planned for the summer, whether as participant or parent? Are there summer education opportunities you'd like to recommend to others, or ones you'd rate as not worth the price? (Naming details helps, in this context -- which space camp? How much does it cost?)Read Replies (0)

There are expensive dedicated devices that do 3D scanning (like the high-end tablet in Google's Project Tango), and versatile but bulky add-ons, like the Sense from 3D Systems
, but it's not a capability built into the typical cellphone or tablet. That could change, thanks to a microsensor being prototyped now (at low resolution) at CalTech
From The Verge's coverage:The tiny chip, called a nanophotonic coherent imager, uses a form of LIDAR (Light Detection And Ranging) technology to capture height, width, and depth information from each pixel. LIDAR, which shines a laser on the target and then analyzes the light waves that are reflected back to the sensor, are best known for their use in precision-guided missile systems and self-driving cars.
While LIDAR itself isn't new, [project lead Ali] Hajimiri explains that "by having an array of tiny LIDARs on our coherent imager, we can simultaneously image different parts of an object or a scene without the need for any mechanical movements within the imager." Each "pixel" on the new sensor can individually analyze the phase, frequency, and intensity of the reflected waves, producing a single piece of 3D data. The data from all of the pixels combined can produce a full 3D scan. In addition, the researchers' implementation allows for an incredibly tiny and low-cost scanner, all while maintaining accuracy. According to the researchers, the chip can produce scans that are within microns of the original.Read Replies (0)
