Radiometry and the detection of optical radiation - OSTI.GOV
WebThis book presents a unified treatment of radiometry and detection, at a graduate level. It discusses some of the basic aspects of radiation transfer through optical systems, and infrared radiation detection by optical methods. WebLasers also emit EM radiation in these "optical frequencies." The higher frequencies of EM radiation, consisting of x-rays and gamma rays, are types of ionizing radiation. Lower frequency radiation, consisting of ultraviolet (UV), infrared (IR), microwave (MW), Radio Frequency (RF), and extremely low frequency (ELF) are types of non-ionizing ... publishing bloomsbury
