                         instruments have been highly successful as high-energy surveyors 
                         and transient-source discoverers and trackers over the past 
                         decades. Albeit having relatively low sensitivity as compared with 
                         focusing instruments, coded-aperture telescopes still represent a 
                         very good choice for simultaneous, high cadence spectral 
                         measurements of individual point sources in large source fields. 
                         Here, I present a review of the fundamentals of CAI instruments in 
                         high-energy astrophysics, with an emphasis on the fundamental 
                         aspects of the technique, coded-mask instrument characteristics, 
                         and properties of the reconstructed images.",
