Patterns of Light : Chasing the Spectrum from Aristotle to LEDs
Light is all around us – even when we do not see it. Our eyes do not detect the higher energy and shorter-than-visible-wavelength ultraviolet radiation, yet we know it is there from the sunburn we receive in Arizona. We know that window glass can block ultraviolet rays so we do not get a burn while driving with the windows rolled up. Our eyes do not detect the low-energy, long-wavelength infrared (IR) radiation but we know it exists from discussions of war applications and televised images of guided weapons targets. We also know about radio waves from the little boxes that talk to us and x-rays from the dentist's office.
Optical imaging and photography : Imaging optics, sensors and systems
This hand book is concerned with optical imaging – from simple pinhole cameras to complex imaging systems. It spans the range all the way from optical physics to technical optics. Based on ray- and wave-optical approaches complemented by principles of Fourier optics, the book discusses the process of imaging from the beginning until image capture where, in particular, the different topics are well integrated with each other.
Imaging Beyond the Pinhole Camera
The world's first photograph was taken in 1826 using a pinhole camera called camera obscura. Cameras used since then are basically following the pinhole camera principle. This book looks at the development as well as the applications of alternative camera architectures.
Combined Scintigraphic and Radiographic Diagnosis of Bone and Joint Diseases
In addition to the bone and joint diseases described in the two earlier editions, this book encompasses novel applications of pinhole scanning to the diagnosis of a broader spectrum of skeletal disorders. It has been considerably expanded to discuss five new themes and is complemented by the addition of some 90 recently acquired cases
