Embodiment
Below in conjunction with embodiment the present invention is done further detailed description.
Described computing machine 1 links to each other with multi-functional data card 2, and links to each other with described prime amplifier 3, turntable driver 6, LASER Light Source 7 respectively through multi-functional data card 2; Fluorescent tube 5 to be measured, is rotated with turntable on the rotating part of described turntable 9 by clamping; Described catoptron 10 and measuring light detector 4 all are fixed in the fixed part of turntable 9; 8 one-tenth 45 ° of angles of light beam that described LASER Light Source 7 sends and semi-permeable and semi-reflecting mirror; Reference light detector 11 is positioned at the transmission direction of this semi-transparent semi-reflecting lens 8, is used to survey the reference light intensity of transmission; Described catoptron 10 is positioned within the reflected light direction and fluorescent tube to be measured 5 of described semi-transparent semi-reflecting lens 8; Described measuring light detector 4 is positioned at the outside of fluorescent tube 5 to be measured; And be close to fluorescent tube, measured photo-detector 4 receives after described catoptron 10 laser light reflected see through the tube wall of fluorescent tube 5 to be measured; Described catoptron 10 all is fixed on the fixed part of universal stage 9 with measuring light detector 4; Do not rotate with turntable; Described measuring light detector 4 will convert electric signal into through tube wall light intensity to be measured with reference to light intensity respectively with reference light detector 11; Convert digital signal into through prime amplifier 3 amplifications, multi-functional data card 2AD afterwards, by described computing machine 1 analysis and processing.
Described catoptron 10 is fixed on the fixed part of revolving-turret 9 with photodetector 4, does not rotate with turntable 9; And fluorescent tube to be measured 5 by clamping on the rotating part of revolving-turret 9, can be with 9 360 ° of rotations of turntable.
LASER Light Source 7 is the red light semiconductor laser of 675nm wavelength; Be coated with reflectivity 80% on the semi-transparent semi-reflecting lens, the reflectance coating of transmitance 20%; Catoptron 10 is to be cut into 45 ° of angles of axis and to be coated with the reflective coating glass bar by an end face to process; There is perforate at the center of universal stage 9, after center drilling toward mirror 10, this catoptron 10 makes laser beam from fluorescent tube 5 inboard ejaculations to be measured to laser through semi-transparent semi-reflecting mirror reflection; Fluorescent tube 5 to be measured is the parts that cut down from power saving fluorescent lamps, and its length is by the radius-of-curvature decision of fluorescent tube, and the inwall that can not run into fluorescent tube 5 to be measured with the upper end of catoptron 10 is a cardinal rule.
