Selected methods of reduction to the spheroid will now be reviewed, prior to a discussion of additional corrections and computations.

Velocity Corrections to Measured Distances,r c, to describe the distance value d′ actually displayed on a distance meter..where d′ = the distance displayed on the EDM instrument,.c. = the velocity of light in a vacuum,.Δt′ = the measured “flight” time of the signal to the reflector and back,.n. = the reference refractive index of the instrument.

Understanding Your Brain Imaging,There are many ways to measure distances by electronic means. Four basic principles will be presented although only one will be discussed in greater depth.

Kazuyoshi Kuwano,Jun Araya,Hiromichi HaraEDM instruments are classified according to the type of carrier wave employed. Instruments using light or IR waves are classified as .. Instruments based on radio waves are generally called .. Because of the different structure of these two types of instruments, they will be discussed separately.

Patrick W. Galbraith,Jason G. KarlinDistance meters featuring visible light or near infrared (NIR) radiation as carrier waves are called electro-optical EDM instruments. These carrier waves follow the laws of geometrical optics; normal telescopes are used for transmitting and receiving the signals.
