Abstract:
Embodiments of the present invention include a device for removing energy from a beam of electromagnetic radiation. Typically, the device can be operatively coupled to a turbidity measuring device to remove energy generated by the turbidity measuring device. The device can include a block of material having one of a plurality of different shapes coated in an energy absorbing material. Generally, the device can include an angled or rounded energy absorbing surface where the beam of electromagnetic radiation can be directed. The angled or rounded energy absorbing surface can configured to deflect a portion of the beam of electromagnetic radiation to a second energy absorbing surface.
Abstract:
Adevice (100) formeasuringfloatingmicro-organismsaccording to the present embodiment comprises an air flow path (250) through which air including floating micro-organisms flow, a first main body (210) which is provided on a side of the air flow path (250) and has a first space portion (231) and a second space portion (233), a second main body (220) which is provided on the other side of the air flow path (250) and in which a collecting portion (260) for collecting the floating micro-organisms are installed, a light emitting unit (310) which is installed in the first space portion (231) and emits a preset wavelength region of light toward the collecting portion (260), and a light receiving unit (370) which is installed on the second space portion (233) and detects a fluorescence signal generated from light which acts on riboflavin contained in the floating micro-organisms.
Abstract:
An image pickup (100) including a lens array (2) having a substrate on which multiple lenses (21a,21b) are provided; a filter (4) including at least two polarizer areas (41a,41b) with respective perpendicular axes which are separated according to beams of light which have passed through the respective lenses (21a,21b) of the lens array (2); an image pickup unit (6) including multiple image pickup areas (62a,62b) that shoots images of an object by receiving the beams of light which have passed through the respective corresponding polarizer areas (41a,41b) of the filter (4); a signal processing unit (8) that processes image signals of the images of the object shot in the multiple image pickup areas (62a,62b) of the image pickup unit (6), wherein a vertical polarization image is shot at one of the image pickup areas and a horizontal polarization image is shot at another image pickup area, and wherein the signal processing unit (8) produces an image according to the polarization ratio of the vertical polarization image to the horizontal polarization image shot in the image pickup unit (6).
Abstract:
An optical beam dump (30), (51) having a passage defined by a passage wall and an optical filter (33), (55) located in an opening in that passage wall. The optical filter (33), (55) being arranged to direct light reflected from that filter (33), (55) along the passage away from an optical input (32), (65) to the beam dump. The passage may be formed as a tube (31), or may be cut within a block of material (52). The passage may have a plurality of bends. Provision for the flow of purging air through the beam dump is made by providing holes (36), (61) in the passage wall.
