59 results about "One-way mirror" patented technology

A one-way mirror, also called two-way mirror (or one-way glass, half-silvered mirror, and semi-transparent mirror), is a reciprocal mirror that is reflective on one side and transparent at the other. The perception of one-way transmission is achieved when one side of the mirror is brightly lit and the other side is dark. This allows viewing from the darkened side but not vice versa.

On-vehicle multiple-beam optical phased array laser three-dimensional imaging radar system

An on-vehicle multiple-beam optical phased array laser three-dimensional imaging radar system relates to the technical field of radar engineering and settles problems of short-distance object detection and low imaging frame frequency in an existing laser three-dimensional imaging system. The on-vehicle multiple-beam optical phased array laser three-dimensional imaging radar system comprises a multi-beam laser module, a transmitting module, a receiving module, a central processor and a distance measuring unit. The multi-beam laser module comprises a beam splitter, a phase modulator array, a fiber amplifier array and a collimating beam spreading array. The transmitting module comprises a unidirectional glass array and an optical phased array. The receiving module comprises an optical filterarray, a double-bonding-lens array, a surface array APD array, a quenching circuit and a distance measuring unit. A ground objective area is scanned through multiple laser beams, thereby obtaining corresponding point cloud data. The obtained data are processed, thereby realizing objective three-dimensional image reconstruction with advantages of high frame frequency, high resolution and large visual field. A detecting task to a ground object is finished in real time in high speed. The on-vehicle multiple-beam optical phased array laser three-dimensional imaging radar system has advantages of high measurement speed and high measurement precision.

High-brightness LED linear light source

InactiveCN107895755AHigh refractive indexSolve the problem that the low light brightness cannot be improved and affect the use of LED linear lightsSemiconductor devicesRefractive indexLight reflection
The invention discloses a high-brightness LED linear light source, which comprises an LED linear light source body. The outer side of the LED linear light source body comprises an outer shell. A lightsource equipment room is arranged in the outer shell. A light source circuit board is arranged in the light source equipment room. An LED light source assembly is fixedly arranged at the top of the light source circuit board. According to the invention, the refractive index of the light source is improved by matching a light-reflecting and refraction layer on the inner side of the light source with a reflector arranged inside the light source, so that the refraction frequency of the light is increased. Therefore, the light source inside a high-illumination chamber is brighter. The light of the light source is reflected through a reflective film, so that the light source is refracted out of a light-transmitting plate. The illumination intensity is improved. The light-transmitting plate iscomposed of the one-way reflecting glass and a reflecting and connecting inner layer. The one-way reflecting glass is extremely strong in light reflection effect, so that the brightness of the light source is improved. The advantage of high brightness is achieved. The problems that the illumination brightness of an existing LED linear lamp is low and cannot be increased so as to influence the usage of the existing LED linear lamp can be effectively solved.

High-shielding reflection film and manufacturing process thereof

Disclosed are a high-shielding reflection film and manufacturing process thereof. The high-shielding reflection film comprises an optical reflection film, a polaroid and a combining layer, the optical reflection film consists of multiple layers of stacked dielectric optical films made of different materials, the polaroid can absorb parts of light emitted to the polaroid and can generate a polarization state, and the optical reflection film and the polaroid are fixedly combined in a specific mode by the combining layer. The optical reflection film consists of the multiple layers of stacked dielectric optical films made of the different materials, by the aid of an optical interference principle, most of light emitted into the optical reflecting film can be reflected, and parts of the light penetrates through the optical reflecting film. About a half of the incident light can be absorbed by the polaroid while the other half of the incident light penetrates through the polaroid. By the aid of different reflection characteristics of the materials of the optical reflection film and the polaroid, difference of reflectivity is increased. Accordingly, by the aid of the high-shielding reflection film, difference of reflectivity of incident light in different directions can be greatly increased, and the high-shielding reflection film achieves a privacy effect of a one-way mirror.
