Abstract: A light sensor includes a primary lens, and a light device spaced from the primary lens. A control structure is disposed between the primary lens and the light device. An actuator is coupled to the control device to move the control device relative to the primary lens and the light device to control the passage of light between the primary lens and the light device. The light sensor may include a light emitting sensor having an array of individual light emitters, or a light detecting sensor having a light detector. The control structure may include an array of secondary bi-telecentric lenses for use with the light emitting sensor, or a plate having an aperture extending therethrough for use with the light detecting sensor.

Abstract: A low-cost laser power sensor having sufficient measurement accuracy with respect to received light intensity of the power sensor. The power sensor has a sensor substrate which receives monitor light, and a filter which attenuates the intensity of the laser beam before being received by the sensor substrate. The filter is constituted from a material having a laser transmissivity equal to zero, and has a plurality of openings within an irradiation range where the monitor light is irradiated. A summation of opening areas of the openings is equal to or more than 50% of the irradiation range. A part of the laser beam, which is irradiated to the filter and passes through the openings, is directly received by the sensor substrate.

Abstract: In an embodiment, an arc light sensor includes: a first polarizer, a second polarizer, a magneto-optical material, a first light filter and a processing unit. The first polarizer is used for polarizing incident first target light, to form first polarized light in a first polarization direction. The second polarizer is used for polarizing incident second target light, to form second polarized light in the first polarization direction. The magneto-optical material, in a current magnetic field, uses the current magnetic field to rotate a polarization direction of the first polarized light, to form third polarized light. The first light filter is used for filtering the third polarized light, to form fourth polarized light capable of passing in a second polarization direction. The processing unit is used for determining whether the second target light is arc light according to intensity of the second polarized light and intensity of the fourth polarized light.

Abstract: A sky luminance mapping system includes a camera unit, two pyranometer units and a processing unit. Camera unit includes a fisheye lens to shoot image of sky dome and is equipped with light-shading devices which block the sun from the camera unit corresponding to instant location of the sun at instant time. First pyranometer unit measures daylight illuminance from the sky dome and outputs first intensity signal while the light-shading device is applied to block the sun. Second pyranometer unit measures daylight illuminance from the sky dome and outputs second intensity signal without blocking the sun. A reference intensity value is obtained by subtracting a value of the first intensity signal from a value of the second intensity signal. According to the value of the first intensity signal and the reference intensity value, a total luminance of and the luminance distribution in the image of the sky dome are corrected.
