Title: High-sensitivity laser length measuring device
Inventor: YOKOYAMA SHIYUUKO
IPC: G01B9/02
Filed: 1993-11-26
Abstract: PURPOSE:To control the oscillation frequency of a transmitter so as to eliminate fluctuation in frequency difference by controlling the heater current by a DC and superposing a random alternating signal, the average value of which is zero, or a sinusoidal or other waveform alternating signal on the DC. CONSTITUTION:A heater 18 is wound round the outer wall of a case of a crystal oscillator 2, and an electric current flowing through the heater 18 is controlled to eliminate fluctuation in frequency difference of the oscillation frequency. Difference frequencies of multiplication devices 3, 4 are obtained by a mixer 7, a difference in frequency between the other reference oscillator 12 and the mixer 7 is detected by a frequency detecting circuit 13, and the difference is converted into pulses by a positive and negative pulse generating circuit 14 for outputting a pulse of the polarity corresponding to the positive or negative number. The rate of the pulse is converted into voltage by a rate meter 15 to control the current of the heater 18 through an addition amplifier 24 and a power amplifier 17. At this time, AC voltage is generated by an AC signal generator 16 to be superposed on a DC control signal by the amplifier 24. Accordingly, as the current approaches its desired value, the current flowing through the heater 18 becomes square so that the gain of a loop is remarkably lowered.
