A target scene generator for testing an imaging ladar in a Hard Ware in the Loop arrangement, such as might be employed for testing an optical seeker on a guided missile, the generator comprising an array of pixel elements 10, a photodetector 20 for detecting incident light from a ladar a laser source 18 for generating pulses of light representing returned ladar pulses, and a reconfigurable fibre network 14 including an optical switch selectively coupling the laser 18 to the pixel elements, and a controller 22 which selectively reconfigures the fibre network, to present to selected pixel elements the pulses of light with selected time delay characteristics such that light emitted from the pixels represent light returned from a target illuminated by the ladar.
