Abstract
PURPOSE: To realize an accurate and simultaneous measurement and monitor for both the rotational frequency and the deviation of vibration of the shaft through a simple and small-sized constitution, by detecting optically the slit and the edge of the disk which turns in a body with the shaft.
CONSTITUTION: The light emitted from light emitting element such as an LED or the like transmits through slit 31 of rotary disk 32 which is formed in a body with shaft 1 and is then received by photodetector 43 such as a photosensor or the like. And the rotational frequency of shaft 1 is measured by mesuring circuit 46. At the same time, part of light emitting element 42 is cut off by the edge of disk 32, and thus the emitted light cut off partially is received by photodetector 44 such as an image sensor or the like. And circuit 46 measures the deviation of vibration and others o shaft 1. As a result, both the rotational frequency and the deviation of vibration can be measured simultaneously and with no contact in a high accuracy to be monitored through a simple and small-sized constitution.
