<p>A system may include an imaging apparatus and an access device. The imaging apparatus may include a light source that emits at least light having one or more wavelengths in the range of about 700 nanometers to about 2,500 nanometers, a camera that is (a) sensitive to light having a wavelength in the range of about 700 nanometers to about 2,500 nanometers, and (b) so positioned relative to the light source as to receive light having a wavelength in the range of about 700 nanometers to about 2,500 nanometers that has been (i) emitted from the light source and (ii) reflected from a target, a processor that forms an image signal based at least in part upon signals indicative of the light having a wavelength in the range of about 700 nanometers to about 2,500 nanometers that is sensed by the camera, and a display screen so coupled to the processor as to receive the image signal and to display an image. The access device may include a hollow, stiff, steel needle having an outer surface, at least a portion of which outer surface is (a) coated with a coating the predominantly reflects such light, (b) coated with a coating that predominantly absorbs such light, and/or (c) irregularized.</p> |
