Abstract: A stroboscope with an integral optical reflective sensor, which can be removable or fixed, contains a light emitting source, a light sensitive receiver, a pulse conditioning circuit, a stroboscope circuit, a blanking circuit, and a stroboscope light source. The light emitting source projects a light beam to a reflective target. The reflected light beam from the reflective target is detected by the light sensitive receiver. The pulse conditioning circuit generates a set of electrical pulses coincident with the reflected light beam which are sent to the stroboscope circuit. Depending on the signal received by the stroboscope circuit, the stroboscope light source is triggered. The blanking circuit prevents false triggering of the stroboscope light source by introducing a time delay. The time delay is applied when the stroboscope light source is switched on and for a finite time after the stroboscope light source is switch off.

Abstract: Disclosed are systems and methods for measuring rotational speed of an object rotating about a non-fixed axis of rotation. The system comprises a source unit capable of emitting source signal; a receiving unit capable of receiving the source signal synchronous with rate of rotation of the object; and a process and display unit communicatively coupled to the receiving unit, the process and display unit capable of determining and displaying rotational speed of the object.
