Disclosed herein are TV Camera based and other electro-optical sensors and systems, providing affordable methods and apparatus for high speed determination of dimensions and other features of objects. Particular embodiments capable of fast and reliable acquisition of features of moving objects such as boards and wood products are disclosed. Preferred embodiments utilize laser triangulation range detection with at least two cameras viewing the same laser spot or line projected on the object. on a camera, enabling said amplitude encoded characters to be displayed by a display device coupled to said camera. 26. Apparatus of claim 16 including raster scanning means coupled between said array of detectors and said display device. 27. An image identification system comprising: (a) a multiplexed filter store for storing a plurality of filters derived from prior examination of a plurality of input image reference samples; (b) input imaging means for capturing an input image under examination; (c) a spectrum analyzer for producing spectral data representing the frequency spectrum of said input image under examination; (d) mapping means for producing a spectrum encoded map of said spectral data representing the frequency spectrum of said input image under examination; (e) first transform means for transforming said spectrum encoded map and directing the resulting transform at said multiplexed filter store; (f) second transform means for producing close match spectral correlation light beams emerging from said multiplexed filter store, each beam having particular beam characteristics with respect to said multiplexed filter store associated with that filter within said multiplexed filter store producing a close match with the resulting transform produced by said first transform means; and (g) detector means positioned in the path of said close match spectral
