Abstract

An inexpensive, broadband technique for testing laser rangefinder systems. The invention includes a mechanism (18) for detecting an emission of a pulse of electromagnetic energy by a laser rangefinder under test (12) and providing a first signal in response thereto. In response to the first signal, a second signal is generated (20) with a predetermined delay on detection of the pulse from the laser rangefinder (12). The second signal is used to trigger a radiation source (16) which generates an output signal. This output signal simulates a return signal, the reflection of the pulse from a hypothetical target back to the laser rangefinding system.
