1. A pointing system for correctly aiming an image recording apparatus towards a human subject, comprising:
- means for producing a plurality of discrete, visible aiming beams of laser radiation, at least two of which are separated from each other by a distance slightly greater than the diameter generally of an eye-pupil of a human subject to prevent said two beams from simultaneously impinging on the eye-pupil when they are pointed towards the human subject; and

Abstract
A camera includes a laser diode for emitting visible laser light towards a human subject whose image is to be recorded. The laser light is divided into a plurality of discrete, aiming beams of radiation by a pair of holographic and/or diffractive elements. The discrete beams are separated by a distance of at least about 7 mm. The laser light identifies where the camera is being aimed without damaging the retina of the human subject.
