IPC: G02B21/00
Filed: 1992-05-29
Abstract: PURPOSE:To enable simple alignment of a whole plane even when one part is measured by providing a high-power observation system, a picture processing system and an operation portion to calculate a shifted amount. CONSTITUTION:Laser light is gathered at a focusing disk 111 and focused on the plane of a pin hole disk 112 via a beam splitter 12. A pin hole in the disk 112 can be observed, with a transmissive lighting 7 through a microscope. A beam spot on the plane of the disk 112 is photographed by a camera 3 via a high-power relay lens 2a at the pin hole position and the center coordinates of both positions are found by a picture processing operation portion 8. Next, a high-precision shifted amount is calculated from two pairs of center coordinates in accordance with a preset equation and adjusted at a XY theta stage 5. In this way, as the positions of the beam spot and the pin hole are observed at high power, the center coordinates are found by the operation portion 8 and a light-precision adjusted amount is calculated from a two-pair positional relationship for adjustment at the stage 5, simple alignment of a whole plane is allowed even if one part is measured.

The motor's torque is also controlled by feeding back the motor current through a current feedback circuit 12. At the time of diagnosis, the motor is caused to run at a fixed speed depending on a load when a fixed voltage is applied to the drive circuit 11 by changing over switches 17, 18 and also by feeding back the voltage through a voltage feedback circuit 13. Under this condition, the diagnosis of the tachometer is carried out by counting the duty ratio and phase difference is carried out by counting the duty ratio and phase difference of tachometer pulses of 2 phases.
