Abstract
Various approaches to touch sensing systems are disclosed As an example, a touch sensing system is disclosed that includes: an optical beam source to provide an optical beam; a pair of controllable beam deflectors comprising at least first and second beam deflectors, wherein the first beam deflector is configured to deflect the optical beam through a first angle towards a touch sensing region, and wherein the second beam deflector is configured to deflect scattered light from an object in the touch sensing region through a second angle; a detector, in particular a detector array; and an imaging system to image the deflected scattered light from the second beam deflector onto the detector array. The first and second beam deflectors are controlled in tandem to scan the touch sensing region.
