An apparatus for measuring brightness transmitted by a light-emitting display unit of a laser telescope and observed by the user's eyes comprises a focusing unit (), a sensor unit (), a processing unit () and a display unit (). A method of measuring brightness includes the steps of: providing a constant color temperature to simulate the external light; providing a tool platform and locating the apparatus for measuring brightness and the laser telescope under test thereon; further providing a light-impermeable cover to cover the laser telescope and the apparatus for avoiding the external light interfering with the measurement of brightness; then turning on the laser telescope and enabling it to range; picking up the light of a reticle and a measured value transmitted from the light-emitting display unit by means of the apparatus for measuring brightness; and at last, displaying the measured value on the display unit of said apparatus for measuring brightness.

Method and apparatus for measuring brightness

A scanning unit includes a lamp-mounting body having a top surface formed with an elongate opening that is disposed between a pair of parallel first and second grooves. First and second reflective layers are attached respectively over curved groove-defining surfaces of walls defining respectively the first and second grooves. Tubular first and second lamps are mounted respectively in the first and second grooves. An intersecting line of a first plane in which a middle line of the curved groove-defining surface defining the first groove and a first central axis of the first lamp are disposed, and a second plane in which a middle line of the curved groove-defining surface defining the second groove and a second central axis of the second lamp are disposed, is located on a scanning surface, and is disposed directly above the opening.
