Abstract:
1. A hand-supportable planar laser illumination and imaging (PLIIM) based camera system having a working range and for producing digital linear images of a object, containing pixels having a substantially uniform white level, said hand-supportable PLIIM based camera system comprising: a hand-supportable housing having a light transmission aperture: a PLIIM-based linear imaging subsystem mounted within said hand-supportable housing, and having wherein said PLIB and FOV are arranged in a coplanar relationship along the working range of said PLIIM based camera system so that the PLIB illuminates primarily within said FOV of the IFD module; an object velocity measurement subsystem disposed within said hand-supportable housing, for determining the velocity of the object relative to said hand-supportable housing and generating control data indicative of the determined velocity of the object; a micro-controller, mounted within said hand-supportable housing, for controlling the operation of said PLIIM-based linear imaging subsystem, in response to control data generated by said object velocity measurement subsystem, wherein said micro-controller (1) uses said object velocity data to compute the optical power which each laser diode in said PLIIM-based linear imaging subsystem must produce in order that each digital linear image capture by said PLIIM-based linear imaging system will have pixels with a substantially uniform white level, independent of object velocity; and (2) generates and transmits control signals to said laser diodes in order to control the operation thereof so that said PLIIM-based linear imaging subsystem produces digital linear images of said object, wherein the pixels in each said digital image have a substantially uniform white level independent of the measured object velocity.
