Apparatus for analyzing fluid or surfaces within a pipeline or vessel includes a probe positioned to capture or record images through a viewing port of the pipeline/vessel and an illumination assembly arranged to illuminate the fluid/surfaces within the pipeline/vessel adjacent the port with visible, infrared or ultraviolet light of a predetermined wavelength or within a predetermined range of wavelengths. Depending upon the type of fluid, light or radiation of a particular wavelength may be required to capture an image of high contrast and clarity. Accordingly, an electronic controller communicates with the probe and the illumination assembly for automatically controlling operation thereof so that images are captured and recorded of the fluid illuminated with light of different predetermined wavelength or predetermined range of wavelengths. An analyzing unit analyzes the images and identifies an image of greatest level of contrast or clarity and the wavelength or predetermined range of wavelengths of the light used to illuminate the fluid for the image of greatest level of contrast or clarity. A method is also disclosed.

A portable laser source includes a flash lamp assembly defining a hollow central channel, an elongate laser rod extending within the hollow channel for receiving a flash of light emitted by the surrounding flash lamp assembly, and a hermetically-sealed enclosure housing both the flash lamp assembly and the laser rod and including at least one optical transmission window for transmitting a laser beam emitted by the laser rod. Preferably, the flash lamp assembly is hermetically-sealed from the laser rod within the enclosure to maintain physical and electrical isolation of the laser rod from combustible and electrically conductive components of the flash lamp assembly. The combustible component of the flash lamp assembly can include Zr wool and an accelerant, or like materials for emitting a flash of light. The laser source can include a second window used to test the condition of the laser rod via application of an external test light to activate the laser rod within the sealed enclosure.

A dart board apparatus including a housing having a spider located therein. The spider is generally circular in shape and has a series of circumferentially and radially extending ribs which define a plurality of target segment openings, and a circumferential center rib which defines a center opening. A plurality of target segments are slidably disposed in the target segment openings. An annular outer bull segment, having a target surface with a center opening, and a generally tubular sidewall with at least two slots therethrough, is also provided. The outer bull is slidably disposed for movement within the center opening in the circumferential center rib. An inner bull segment is slidably disposed within the center opening in the outer bull segment. The inner bull segment includes at least two spokes, in an aligned position with the slots in the outer bull segment sidewall. Each spoke includes a first end connected to the inner bull, and a second end in slidable contact with the circumferential center rib so that the inner bull segment may slide independently of movement of the outer bull segment. At least one sensor is associated with each target segment, the outer bull segment and the inner bull segment.
