Abstract:
An ophthalmic endo-illumination system (206) includes a light source that produces a light beam (305), a fiber port that receives an optical fiber (310), a condenser (302) that couples at least a portion of the light beam into the optical fiber received at the fiber port, and a beam splitter (304) disposed between the fiber port and the condenser. The beam splitter is configured to receive the light beam from the condenser and split the light beam into a first beam (312) which is coupled to the optical fiber and a second beam (314) which is coupled to a monitoring fiber (306). An optical sensor (308) is provided to detect an amount of the second beam output from the monitoring fiber. The coupling efficiency of the first beam coupled into the optical fiber may be determined based on the amount of the second beam output from the monitoring fiber.
Abstract:
The invention provides a control device for controlling at least one wirelessly connected lighting device within a wireless network, wherein the control device comprises: a transceiver configured to overhear and transmit a message within the wireless network; a light sensor configured to detect a light signal comprising a temporal characteristic that is characteristic for a first artificial light source; a processor operatively coupled to the light sensor and the transceiver, wherein the processor is configured to: determine, based on analyzing said temporal characteristic, a first condition that the light signal belongs to the of artificial light source, and transmit a control message to the at least one wirelessly connected lighting device upon determining said first condition.
Abstract:
A lighting array and a method of using the same facilitate a lighting strategy that dynamically provides the photosynthetic photon flux density needed by a plant throughout its stages of growth while reducing power loss and waste caused by providing excess light during all stages of plant growth. LED placement patterns may be used to form a number of lighting channels on an LED board or an array of LED boards. These lighting channels may be individually controlled such that the ON/OFF state, intensity, and wavelength, of a plurality of LEDs may be adjusted to provide variable illumination levels and wavelengths of light customized for attributes of the plants being illuminated, such as their stage of growth, size, type, and/or shape.
Abstract:
An ophthalmic endo-illumination system includes a light source producing a light beam, a beam splitter configured to split the light beam into a first beam provided to a fiber port and a second beam coupled to a monitoring fiber, and an alignment system for aligning the monitoring fiber. The alignment system includes a moveable ferrule housing having the monitoring fiber secured therein and a displacement mechanism for displacing housing in a first direction. The displacement mechanism includes a transfer spring coupled to the housing and a screw actuator having a sloped surface contacting a motion transfer ball such that movement of the screw actuator causes the motion transfer ball to move along the sloped surface, the motion transfer ball contacting the transfer spring such that movement of the motion transfer ball along the sloped surface causes a displacement of the transfer spring, thereby displacing the housing in the first direction.
Abstract:
A system and method for pre-aligning a light beam in a spectroscopic measuring device such as a pump-probe device prior to conducting a measurement procedure is provided, which eliminates the need for monitoring or modification of the beam trajectory through adjustments of elements transmitting the beam (e.g., mirrors) over the course of a measurement process.
Abstract:
A system and method for aligning a light beam in a spectroscopic measuring device such as a pump-probe device is provided. The system and method comprise a first motorized mirror (66b) positioned to receive and transmit a light beam (60a); a second motorized mirror (66c) positioned relative to the first mirror to receive the light beam from the first mirror and transmit the light beam to a delay line (64); a third mirror (78) positioned to receive the light beam from the delay line and transmit said light beam to a detector (80); and a computer- based processor (82) in communication with the detector and the first and second mirrors, the processor configured to a) receive and process data relating to the light beam from the detector, and b) cause movement of the first and second mirrors to change an angle of the mirrors based on the data relating to the light beam.
Abstract:
Es wird ein Lichtsensor (101) für eine Beleuchtungseinrichtung (113), ein Beleuchtungssystem umfassend mindestens einen Lichtsensor (101) und ein Verfahren zur Einstellung einer Helligkeit eines Beleuchtungssystems umfassend mindestens einen Lichtsensor (101) vorgeschlagen. Diese ermöglichen eine Anpassung des Lichtsensors (101) an einen Abstand (115) zu einem entfernten Boden oder einem sonstigen entfernten, zu beleuchtenden Bereich (114), worunter insbesondere auch Hallenböden mit einer Deckenhöhe von mehr als 5 m fallen.
