Abstract

PURPOSE: To prevent the spot from shaking and realize accurate indication, by providing a mirror to deflect a spot luminous flux, manipulating this deflector manually or electrically, and installing the device in fixed or semi-fixed structure.
CONSTITUTION: A luminous flux 2 from a laser tube 8 is deflected by a mirror and projected on a screen 1. The mirror is divided into two mirrors, 22 and 23, and each one is responsible for moving in lateral and vertical direction. The mirrors 22, 23 are, as rotating mirrors, set in the angle of rotation by means of galvanometers 20, 21, respectively. The galvanometers 20, 21 are driven by DC amplifiers 24, 25, and the DC signals applied from X-Y potentiometer 26 are amplified, and are presented for the use in deflection of luminous flux. When an operator handles a handle 6 and a knob 7 on the X-Y potentiometer 26, a spot 10 on the screen 1 may be moved accurately to an arbitrary position as desired.
