How to Calculate Angular Speed of Electric Motor by using Optical Sensor ?

I want to calculate the angular speed of motor. An optical sesnor is attached to count the pulses. In MAT file i have binary data (0 or 1) from the optical sesnor. My question is that how i can calculate the angular speed of motor from this binary data ?

Well, need to know how many pulses/revolution the sensor provides and the timing of the sampling.

After that, it should be pretty straightforward.

1 pulse/revolution, Sampling Time is 1e-3 sec.

Since 1revolution=1pulse, Angular Speed= Number of pulses/(Number of sample data * Sampling time)
