Abstract: Systems and methods are described, including a system (100) for automatically ascertaining a height characteristic of a contaminant (104) on a travel surface (102). The system (100) comprises an illumination and imaging device (106). At a first time, when the travel surface (102) is generally free of contaminant, the illumination and imaging device (106) illuminates the travel surface (102) with at least one light beam (119), and images at least one impingement of the at least one light beam (119). At a second time, when the travel surface (102) is covered by a layer of contaminant (104), the illumination and imaging device (106) illuminates the travel surface with a light beam (132), and images an impingement of the light beam on an impingement surface (107). In response to the imaging, a computer (130) calculates the height characteristic of the contaminant. Other embodiments are also described.

Abstract: Systems and methods are disclosed for automated inspection and part enrollment. In one implementation, a selection of an area of a part is received within a graphical user interface depicting a representation of the part. Based on the selection of the area of the part, a location of the selected area is determined. Image capture parameter(s) are determined based on the determined location. Based on (a) the determined image capture parameters and (b) the location of the selected area, an inspection path is computed with respect to the part. The computed inspection path is executed with respect to the part via an inspection system.

Abstract: A method includes accepting an analog input signal including a sequence of pulses of a given pulse shape. The analog input signal is distributed to multiple processing channels (40) operating in parallel. The analog input signal is sampled by performing, in each of the multiple processing channels, the operations of: mixing the analog input signal with a different, respective modulating waveform to produce a mixed signal; filtering the mixed signal; and digitizing the filtered mixed signal to produce a respective digital channel output.
