Abstract:
An optically-induced dielectrophoresis device includes a first substrate, a first conductive layer, a first patterned photoconductor layer, a first patterned layer, a second substrate, a second conductive layer, and a spacer. The first conductive layer is disposed on the first substrate. The first patterned photoconductor layer is disposed on the first conductive layer. The first patterned layer is disposed on the first conductive layer. The first patterned photoconductor layer and the first patterned layer are distributed alternately over the first conductive layer. Resistivity of the first patterned photoconductor layer is not equal to resistivity of the first patterned layer. At least one of the first substrate and the second substrate is pervious to a light. The second conductive layer is disposed on the second substrate and between the first substrate and the second substrate. The spacer connects the first substrate and the second substrate.

A particle manipulation system and a projection device are provided. The projection device includes an image source and a projection lens. The image source provides an image beam. The projection lens is disposed on a light path of the image beam and includes a zoom lens set and a focusing lens set. The zoom lens set is disposed on the light path of the image beam from the image source and includes at least two lens groups disposed in sequence on the light path of the image beam. The focusing lens set is disposed on the light path of the image beam. The zoom lens set is disposed between the image source and the focusing lens set. A photoconductor chip is disposed on the light path of the image beam from the projection lens.

Abstract:
A light communication system, a transmitter and a receiver are provided. The light communication system includes the transmitter and the receiver. The transmitter has a first processing unit and a light-emitting element. The first processing unit produces a transmission signal. The light-emitting element produces light to carry the transmission signal. The receiver has a first variable lens, a photosensitive element and a second processing unit. The first variable lens changes the propagation path of the light. The photosensitive element senses the light passed through the first variable lens to produce a receiving signal. The second processing unit controls the first variable lens based on the signal quality of the receiving signal to change the equivalent channel between the transmission signal and the receiving signal. Therefore, the transmission capability of the light communication system is enhanced.
Abstract:
A projection lens, a projection device and an optically-induced microparticle device are provided. The projection lens includes an aperture, a first and a second lens groups. The aperture, the first and the second lens groups are disposed on a projection path of an image. The aperture is between the first and the second lens groups. The first and the second lens groups are suitable for interchanging with each other to switch the magnification ratio. When in a first state, the first lens group is between the object and the aperture and the second lens group is between the aperture and a projection surface, herein the projection lens has a first magnification ratio. When in a second state, the first lens group is between the aperture and the projection surface, and the second lens group is between the object and the aperture, herein the projection lens has a second magnification ratio.
