We consider a dense stellar system containing a massive collapsed object. When an orbiting star goes behind the black hole, gravitational deflection of light in the hole's gravitational field may considerably increase its apparent luminosity, giving rise to a short light pulse. The paper analyzes such a 'gravitational focusing' effect for a Newtonian spherically symmetric stellar system containing at its center a Schwarzschild black hole; counting rate, pulse length and amplitude distributions are evaluated assuming a steady-state distribution of stars in a characteristic region near the black hole. The effect, which depends mainly on the fraction of collapsed mass in the system, appears to provide a possible observational test for massive black holes. Its detection should be feasible with present techniques for a compact globular cluster containing a collapsed object of some thousandths the total mass.
