Title: Speed-difference measuring apparatus
Inventor: SAKATA MASAO
IPC: G01P3/60
Filed: 1985-06-10
Abstract: PURPOSE:To enable highly accurate detection of difference between right and left speeds of an automobile, by a non-contact measurement using an optical spatial filter. CONSTITUTION:The output signal of one spatial filter speedometer 10a is inputted into a frequency measuring circuit 30 and the speed detection output is obtained from the circuit 30. Moreover, both outputs of the spatial filters 10a and 10b are inputted into a multiplication circuit 31 and a signal containing a sum frequency and a difference frequency of output frequencies of the speedometers 10a and 10b is outputted. In other words, a signal containing a sum frequency 2f1+DELTAf and a difference frequency DELTAf is outputted from the circuit 31 when the output frequency of the speedometer 10a is represented by f1 and the output frequency of the speedometer 10b by f1+DELTAf. The output of the circuit 31 is filtrated with a lowpass filter 32 and a signal of the difference frequency DELTAf alone is extracted to be inputted into a frequency measuring circuit 33. The frequency f1 is proportional to the ground speed detected with the speedometer 10a while the frequency f1+DELTAf to the ground speed detected with a speedometer 10b. Thus, the difference frequency DELTAf is proportional to the difference between detection speeds of the speedometers 10a and 10b.
