Abstract
A detector (550) for detecting light (248B) from a light source (248A) comprises a single array of pixels (574) and a first mask (576). The single array of pixels (574) includes a plurality of rows of pixels (574R), and a plurality of columns of pixels (574C) having at least a first active column of pixels (574AC) and a spaced apart second active column of pixels (574AC). The first mask (576) covers one of the plurality of columns of pixels (574C) to provide a first masked column of pixels (574MC) that is positioned between the first active column of pixels (574AC) and the second active column of pixels (574AC). Additionally, a charge is generated from the light (248B) impinging on the first active column of pixels (574AC), is transferred to the first masked column of pixels (574MC), and subsequently is transferred to the second active column of pixels (574AC).
