Radiometry, solid angle, radiometry of thin lenses, from light rays to pixel values, the interaction of light and surfaces,... is the main content of the lecture "Capturing light". Invite you to consult the detailed content lectures to capture details.
The term ‘microwaves’ is used for those wavelengths measured in centimetres roughly from
1 m. to 0.1 cm or the bands of frequencies between 300 MHz to 300 GHz. Microwaves are
most popularly used in point to point communication, TV broadcasting via satellites and in
RADAR systems. Besides these, they are also being used in industrial, biomedical, chemical
and in scientific research applications.
The purpose of this book is to provide the reader with an introduction to lasers
and their industrial applications. To facilitate this objective, such devices as
photodetectors and modulators, which are frequently found in laser applications,
are also covered. And to make the book as self-contained as possible, the
concepts of basic optics that are pertinent to lasers and their applications are
