Abstract: An optical system in a video probe assembly includes a plurality of lenses configured to refract separate linearly polarized rays under different refractive indexes to form a plurality of different focal lengths. The optical system includes at least one light modulating element that modulates a polarization state of the linearly polarized rays passing through the at least one light modulating element in response to a control signal. The optical system includes a polarizer element that filters out some of the modulated linearly polarized rays passing through the polarizer element. A method of inspecting a target with an optical system of a video probe assembly is also provided.

Abstract: A probe system and a method are provided. The probe system includes an emitter unit, a pattern generation system, and an intensity modulator. The emitter unit is for emitting light. The pattern generation system is for projecting at least one reference structured-light pattern onto an object surface to obtain at least one reference projected pattern, and including a mirror scanning unit for reflecting the light to a plurality of directions. The intensity modulator is for modulating intensity of the light according to the at least one reference projected pattern to provide modulated light to the mirror scanning unit to reflect the modulated light to the plurality of directions to project at least one modulated structured-light pattern onto the object surface to obtain at least one modulated projected pattern.

Abstract: An optical imaging system includes a birefringent element, a light modulating element, and a polarizer element. The birefringent element is configured for decomposing un-polarized light into first linear polarized light and second linear polarized light under different refractive indexes to respectively form a first focal length and a second focal length in the optical imaging system. The light modulating element is configured for modulating a state of polarization of the first and second linear polarized light in response to control signals. The polarizer element is configured for filtering out one of the modulated first and second linear polarized light for creating a single image.

Abstract: A stereoscopic optical system that includes an image member that is located at a position along a center optical axis and that has a first stereoscopic image area on a first side of the optical axis for receipt of a first stereoscopic image thereon and a second, separate stereoscopic image area on a second, separate side of the optical axis for receipt of a second, separate stereoscopic image thereon. The system includes an optical arrangement extending along the center optical axis and includes a roof prism with first and second roof segments. The arrangement is configured to transmit image-forming rays passing through the first roof segment to the first stereoscopic image area along a first optical path through the arrangement and is configured to transmit image-forming rays passing through the second roof segment to the second stereoscopic image area along a second, different optical path through the arrangement.
