Abstract:
Imaging devices and illuminating devices are provided. In one exemplary implementation, an imaging device comprises an optical sensor and an illuminator. The illuminator comprises a support frame and a plurality of light emitting diodes (LEDs) connected to the support frame. A first set of LEDs of the plurality of LEDs is configured to provide dark field illumination at a high angle of incidence with respect to an object. The first set of LEDs is configured to provide illumination without the use of a light pipe, diffuser, or reflector. A second set of LEDs of the plurality of LEDs is configured to provide bright field illumination at a low angle of incidence with respect to the object. The second set of LEDs is configured to provide illumination without the use of a light pipe, diffuser, or reflector.
