摘要： A bar code symbol reading system is disclosed comprising a hand-supportable bar code symbol reading device which embodies an electronically-controlled bar code symbol reading engine for producing a raster-type laser scanning pattern in either a hands-free or hands-on mode of operation for scanning 1-D and 2D bar code symbols. The electronically-controlled bar code symbol reading engine has (i) a high-speed/high-resolution raster scanning mode of operation, during which a high-speed, high-resolution raster-type scanning pattern is precisely generated under electronic control, and (ii) a high-speed/low-resolution raster scanning mode of operation during which a high-speed, low-resolution raster-type scanning pattern is precisely generated under electronic control. The electronically-controlled bar code symbol reading engine is induced into its high-speed/high-resolution raster scanning mode of operation when the hand-supportable bar code symbol reading device is removed from its support stand, and into its high-speed/low-resolution raster scanning mode when the hand-supportable bar code symbol reading device is placed into its support stand. The bar code symbol reading engine comprises a pair of mechanically-damped off-resonant laser beam scanning mechanisms that are arranged on a miniature optical bench and electronically-controlled by either a synchronously or synchronously driven drive circuit. When asynchronously driven, the raster laser scanning pattern floats slightly along the y-scanning direction to facilitate reading of 2-D bar code symbols during the hands-on mode of operation.

摘要： Disclosed is laser beam scanning apparatus in the form of an electronically-controlled mechanically-damped off-resonant laser beam scanning mechanism. The scanning mechanism comprises an etched scanning element having a small flexible gap region of closely-controlled dimensions disposed between an anchored base portion and a laser beam deflecting portion The light beam deflecting portion supports a permanent magnet and a light beam deflecting element (e.g., mirror or hologram). A reversible magnetic force field producing device (e.g., an electromagnet) is placed in close proximity with the permanent magnet so that it may be forcibly driven into oscillation in response to electrical current flowing through the electromagnet. The resonant frequency of oscillation of the laser beam deflecting portion relative to the anchored base portion is determined by the closely controlled dimensions of the flexible gap region set during manufacture. The steady-state frequency of oscillation of the laser beam deflecting portion is determined by the frequency of polarity reversal of the electromagnet, which is electronically controlled by the polarity of electrical current supplied thereto. In the illustrative embodiments, the forcing frequency of the electromagnet is selected to be at least ten percent off (i.e., greater or less than) the natural resonant frequency of the laser beam deflecting portion of the scanning element. The steady-state frequency of oscillation can be set at the time of manufacture to be any one of a very large range of values (e.g., 25-127 Hz) for use in both low-speed and high-speed laser scanning systems.

摘要： A hand-supportable linear-type planar laser illumination and imaging (PLIIM) based device comprising a linear image formation and detection (IFD) module having a linear array of image detection elements and also image formation optics having a field of view (FOV) focusing a linear image of an object onto the linear array of image detection elements. A pair of planar laser illumination arrays (PLIAs) is arranged on opposite sides of the linear image formation and detection module, and produces a plurality of spatially-incoherent planar laser illumination beam (PLIB) components that are optically combined with respect to other PLIB components so as to produce a composite planar laser illumination beam (PLIB) that is arranged in a coplanar relationship with at least a portion of the FOV. Each PLIA includes a plurality of planar laser illumination modules (PLIMs). Each PLIM includes a laser diode and beam focusing and diverging optics for producing one spatially-incoherent PLIB component. The composite PLIB produces a number of substantially different individual speckle noise patterns at the linear array of image detection elements during the photo-integration time period thereof. The speckle noise power observed at the linear array of image detection elements is reduced through temporal averaging of the individual speckle noise patterns during the photo-integration time period. By virtue of the present invention, it is now possible to use visible laser diodes (VLDs) to produce speckle-reduced images of objects suitable for OCR processing, while enjoying improved working distances offered by planar laser illumination techniques.

摘要： A hand-supportable planar linear illumination and imaging (PLIIM) based code symbol reading system comprising: a hand-supportable housing having a light transmission aperture; and a planar laser illumination and imaging module (PLIIM), disposed in the hand-supportable housing. The PLIIM includes (i) a linear image detection array having optics providing a field of view (FOV) on said linear image detection array that projects through the light transmission aperture, and (ii) at least one planar laser illumination module (PLIM) for producing a substantially planar laser illumination beam (PLIB) that extends substantially along the same plane as the FOV of the linear image detection array. This arrangement provides a coplanar illumination and imaging plane that projects through the light transmission aperture, for capturing a series of linear (1-D) digital images of an object intersecting therewith during object illumination and imaging operations. An image frame grabber then accesses 1-D digital images therefrom and composes a 2-D digital image of the object. An image data buffer buffers 2-D images received from the image frame grabber, and a decode image processor processes the digital images stored within the image data buffer so as to read one or more code symbols graphically represented in the digital images. A system controller controls the operations within the system.
摘要翻译：一种手持式平面线性照明和成像（PLIIM）代码符号读取系统，包括：具有光传输孔径的手持式外壳; 以及设置在手持式外壳中的平面激光照明和成像模块（PLIIM）。 PLIIM包括（i）线性图像检测阵列，其具有在所述线性图像检测阵列上提供通过光传输孔突出的视场（FOV）的光学元件，以及（ii）至少一个平面激光照射模块（PLIM），用于产生基本上沿着与线性图像检测阵列的FOV相同的平面延伸的基本上平面的激光照明光束（PLIB）。这种布置提供了共面的照明和成像平面，其投射通过光传输孔径，用于在物体照明和成像操作期间捕获与其相交的物体的一系列线性（1-D）数字图像。然后，图像帧抓取器从其中访问1-D数字图像，并且构成该对象的2-D数字图像。图像数据缓冲器缓冲从图像帧获取器接收的2-D图像，并且解码图像处理器处理存储在图像数据缓冲器内的数字图像，以便读取在数字图像中图形表示的一个或多个代码符号。系统控制器控制系统内的操作。
