We study deep inelastic scattering of an electron or positron on an almost real photon target in the reaction e+e → e+e + hadrons with C = +, where one e+ or e is scattered at small or zero angle, yielding a virtual photon γ(k), k2 ∼ O(−me2). The other e or e+ scatters on this virtual photon, emerging at large angle. We emphasize particularly: (i) the pointlike QCD contribution to the structure functions of the photon; (ii) the measurability of the structure functions under realistic experimental conditions; (iii) the background from the inelastic Compton process e+e → e+e + hadrons with C = −, which we find is controllable.
