A high speed, low cost, wide spectrum light scanning and sensor unit ( 10 ) for receiving reflected light from an object and diffracting the light into segments of wavelengths and a linear sensor array ( 32 ) having elements positioned to receive the segments and to measure the relative magnitude of such segments to define a spectral distribution of the object together with a digital identifier-controller ( 36 ) connected to said sensing device and having a memory for memorizing a spectral distribution of light representing a first standard object, and additional memory for receiving a spectral distributions of other objects and programmable logic circuitry containing a program for determining the similarity between the standard object and the other objects.
