They are used as ultra-thin beam splitters, windows, mirrors, and filters!
The pellicle optical elements from National Photo Color Co. are used primarily in spectroscopic devices as ultra-thin beam splitters, windows, mirrors, and filters, due to their film thickness of a few micrometers, which eliminates secondary reflections, spherical aberrations, chromatic aberrations, and refraction anomalies.
Selectable from eight wavelength models. Low noise, high stability, and high-speed pulse compatible. RF drivers can also be provided.
The Aerodiode fiber-coupled AOM (acousto-optic modulator) is capable of low noise, high stability, and high-speed pulse response. Aerodiode offers seven wavelength models, each available in standard and high-speed versions. ■ Wavelength Models 400 nm model (380 - 600 nm) 532 nm model (380 - 600 nm) 635 nm model (550 - 680 nm) 780 nm model (600 - 900 nm) 1064 nm model (940 - 1100 nm) 1310 nm model (1200 - 1430 nm) 1550 nm model (1470 - 1700 nm) 1650 nm model (1470 - 1700 nm) ■ High-speed pulse response (8 ns rise/fall time) ■ High output ■ Low noise, high stability
Conversion of depth information linearly into planar information!
In 3D imaging, it is important to effectively encode z information, which is the image formation displacement of the target object, into XY information, which is displacement from the optical axis of the image surface. On the other hand, in single-pixel imaging using only a single detector, it is important to encode in efficient manner the XY information of the target into the time information. However, the conventional encoding method has a limit on distance resolution, imaging distance range, z information decoding accuracy and encryption uniqueness. This invention provides a new and improved hologram optical element, its manufacturing method and an optical device able to mutually convert Z & XY information with simple configuration. This invention is able to realize high accuracy and high spatial resolution for high-speed 3D imaging (patent US10816474) by converting the object depth direction information of the optical detection system into the planar direction information at the detecting surface.
