PURPOSE:To quickly execute a measurement, to simplify a control, and to set an angle resolution in accordance with a desire, by executing a measurement of a far area three-dimensional light emission analysis for checking the directivity, and a data processing, by turning on simultaneously each LD, and also, rotating continuously a swing arm. CONSTITUTION:Plural pieces of laser diodes LD 1 for executing a measuring inspection are set in a laser cartridge 2, and in accordance with a command from a CPU, a swing arm 5 provided with a far area three-dimensional light emission analysis FFP detector 4 is driven by a driving system 8. A rotational position of this arm 5 is read from an output of an encoder 9, an initial position for a measurement is detected, and thereafter, a laser power source 3 is turned on and the LDs are turned on simultaneously. Also, the arm 5 is fixed to every set position corresponding to the output of the encoder 9, outputs of all detectors 4 are read, and thereafter, the arm is rotated to the next position or rotated continuously, and a measurement of an FFP for checking the directivity and its control are simplified. |
