New Optics See More with Less

NASA's Marshall Space Flight Center has developed a technology that combines a panoramic refracting optic (PRO) lens with a unique detection system to acquire a true 360-degree field of view. Although current imaging systems can acquire panoramic images, they must use up to five cameras to obtain the full field of...

Dual-Field-of-View Multiband Optics

Multi-spectral-band systems are steadily emerging as a desired feature in a camera system. Each spectral band offers different image characteristics. Shorter-wavelength spectral bands provide the potential for better resolution due to the smaller impact of diffraction on the size of the optics blur. This means...

Doctors currently rely on external ultrasound probes, combined with pre-operative imaging scans, to visualize soft tissue and organs during minimally invasive procedures, as the miniature surgical...

Currently there is no reliable way to determine, during tumor-removal surgery, whether the excised tissue is completely cancer-free at its margins — the proof that...
