Science and research

Science and research is a very diverse group with requirments anywhere from short object distance to lightweight optics to rectilinear distortion corrected lenses for image stitching and measurements. Here are just a few examples of locations where Theia's lenses have gone, from the bottom of the ocean to the top of the world.

For many types of scientific missions, there are stringent requirments on size, weight, and power that limit the number of cameras that can be installed. With Theia's ultra wide angle lenses, scientists are still able to capture a large image with only one camera so the area surrounding the site can be effectivly monitored.

All optical distortion correction allows software to more easily stitch together images from multiple cameras. The distortion correction in the lens not only increases the resolution of the image at the edges but also eliminates the time consuming step of image dewarping.

NASA recorded video of a flight using Theia's SY125 lens on a 5MPix StarDot camera from their unmanned aerial drone for the GLOPAC mission. You can see a reduced resolution version (320x240) of the movie by downloading this file (.mov 6.5MB). You can also visit the GLOPAC mission website to see if additional videos have been published.
This latest exmple of Theia's lens in a webcam was installed on the NYU campus to monitor the nest of a red tailed hawk family. Since April 2013, there have been fledgling hawks in the nest. In this application, it is important to be very close to the nest while still seeing a very wide field of view. Visit the live webcam to see more.
Theia's ultra wide angle lenses are great for applications where there is limited distance from the subject. As an example, check out the great blue herons on the Cornell ornithology lab heron-cam. Here the camera is restricted to be close to the heron's nesting site so a wide angle lens captures the entire scene. Visit the live webcam to see more.
NASA's GLOPAC mission studies gasses, dust, and other atmospheric constituants from a Global Hawk unmanned vehicle platform. Theia's lens provides unparalleled coverage, even showing the curvature of the Earth from 60,000ft. Click to see a movie (6.5MB) of the flight over Hurricane Karl. Download a movie of the flight.
NOAA is studying the melting of the north pole ice cap. Every year in winter, a weather station is installed at the north pole including cameras to watch teh melting of the ice. In the summer, the ice under the camera installation melts and the entire apparatus sinks. Theia's lens was installed in the weather station in 2008 and survived temperatures down to -20°C.
National Instruments is using Theia's lenses as part of their NI Week 2010 Robot Swarm Demo. The ultra wide angle SY125 lens allows NI to monitor a large field of robots from a low ceiling height and to accuratly measure position of all the robots in the field. The rectilinear design using Theia's Linear Optical Technology® distortion correction makes X-Y coordinate calculations very simple. See the National Instruments demo
