81,000 Pulses with36mmDiameter

Canon laser rotary encoders use the light-diffraction interference method, with a semiconductor laser as the lightemitter element. The result is an ultra-compact size encoder that combined was impossible with traditional rotary encoders. This product is a compact, high-precision rotary-angle sensor that is certain to play a major role in the development of high-technology products that will lead the market in the 21st century in a wide variety of fields such as robotics, manufacturing machinery, and measuring equipment.

THEORY

As illustrated in the diagram, laser beams are applied to two points equidistant from the grating disc's center of revolution. One diffraction beam is positive first order (+1) and the other is negative first order (-1). For each 1 pitch that the grating disc revolves, the ±1 diffraction light will change each phase by ±2π. Reflecting the ±1 diffraction light into respective mirrors and then reapplying it to the grating disc changes the phase by ±4π.

In this way, each time the grating disc revolves 1 pitch, the brightness interference signals for 4 cycles can be obtained, making highly accurate angle sensing possible.

THEORY

The laser light emitted by a semiconductor laser is positioned so that it is a linearly polarized beam with respect to the zaxis. Then, a collimator lens makes it into a parallel light beam. The grating array direction of this parallel light beam is the direction of the y-axis, and the diffraction grating with a grating pitch d divides the beam into two light beams by a diffraction angle of q. Here, the equation d sin θ = λ holds. These two light beams pass through a first lens and are then irradiated into an E/O frequency shifter consisting of electrooptical crystals. After that, they are diffracted by a second lens before irradiated to the object moving at a velocity of V, which is being measured. The incidence angle of the two irradiated light beams is θ'.

The first and second lenses form an afocal optical system with a magnification of m, and the aberration is corrected so that sin θ / sin θ' = m.

The two light beams that are now modified to have a frequency difference fR by the E/O frequency shifter are then irradiated to the object to be measured, and the diffused beams coming back from the object proceed through the second lens and a condensing lens, eventually reaching the photo diode. The beat signal (i.e., the Doppler frequency) of these light beams containing the speed information obtained here is F=2V/md+fR, independent of the laser frequency; in addition, it is possible to measure the velocity from an object that is originally in a still state.

By signal-processing this Doppler frequency, the unit displays the velocity and sends the F/V output and pulse output.

These instructions provide information that shows users how to use this equipment safely and how to avoid

potential dangers and prevent property losses. You must read these instructions before you perform

installation, operation, maintenance, or inspection of the equipment.

Conventions

The following conventions are used in these instructions.

Warning!
