  A conventional stroboscope uses flashes of light to make a rapidly moving
object visible. This is achieved by throwing repetitive pulses of white light
on the object of specific frequency. Here an alternative approach is given in
which two different colors of light(red/green) are used to make a rapidly
moving object visible. As such this method has two light pulses of different
colors within a single strobe period. Such a stroboscope has its own advantages
in experiments over the conventional one. This article describes the
construction of this stroboscope in all detail. Various aspects of its
performance are discussed pictorially with reference to a simple rotating disc.
This stroboscope can be used in the study/quantitative-assessment of rapidly
moving objects which by default are taken to be cyclic in nature.
