摘要:
Some embodiments of the present invention provide optical coherence tomography systems including an OCT engine and a processor. The OCT engine is configured to provide both standard OCT imaging and spectral domain phase microscopy (SDPM) imaging. The processor is coupled to the OCT engine and is configured to use a first signal processing method when the OCT engine is configured to provide standard OCT imaging and a second signal processing method when the OCT engine is configured to provide SDPM imaging. Related methods and computer program products are also provided.

Methods of analyzing three dimensional data sets obtained from a sample over time are provided. A first three dimensional data set is obtained from the sample at a first time. A first volume intensity projection (VIP) image is created from the first three dimensional data set. One or more first landmarks are identified and registered in the first VIP image. A second three dimensional data set is obtained from the sample at a second time, different from the first time. A second VIP image is created from the second three dimensional data set. The one ore more first landmarks are identified and registered in the second VIP image. The first and second VIP images are aligned based on the registered one or more first landmarks in the first and second VIP images. Related systems and computer program products are also provided.

Methods, systems and computer program products for generating parameters for software dispersion compensation in optical coherence tomography (OCT) systems are provided. Raw spectral interferogram data is acquired for a given lateral position on a sample and a given reference reflection. A trial spectral phase corresponding to each wavenumber sample of the acquired spectral interferogram data is postulated. The acquired raw spectral data and the postulated trial spectral phase data are assembled into trial complex spectrum data. Trial A-scan data is computed by performing an inverse Fourier transform on the trial complex spectrum data and determining the magnitude of a result.

Portable optical coherence tomography (OCT) devices including at least one mirror configured to scan at least two directions are provided. The portable OCT devices are configured to provide a portable interface to a sample that can be aligned to the sample without repositioning the sample. Related systems are also provided.
摘要:
Frequency domain optical coherence imaging systems have an optical source, an optical detector and an optical transmission path between the optical source and the optical detector. The optical transmission path between the optical source and the optical detector reduces an effective linewidth of the imaging system. The optical source may be a broadband source and the optical transmission path may include a periodic optical filter.

Optical imaging systems are provided including a light source and a depolarizer. The light source is provided in a source arm of the optical imaging system. A depolarizer is coupled to the light source in the source arm of the optical imaging system and is configured to substantially depolarize the light from the light source. Related methods and controllers are also provided.

A roofing safety line engagement assembly includes a plate that has a top side, a bottom side and a perimeter edge. The perimeter edge includes a front edge, a rear edge, a first lateral edge and a second lateral edge. The first lateral edge has a plurality of slots therein. Each of the slots engages a nail extended into a roof. The slots are angled toward the front edge such that an angle between each of the slots and the first lateral edge is less than 60°. A catch is attached to and extends upwardly from the plate. The catch is positioned adjacent to the rear edge and releasably engages a safety line.

Disclosed herein is a portable baseball backstop mounted on a vehicle trailer and includes a 3 section fencing unit, with optional fourth section placed above the center portion of the 3 section unit. The backstop is permanently attached or mounted to the trailer and easily placed at the desired location for set up and use by players. The backstop is lifted with the help of a winch/pulley system out of the trailer and set up on the ground with the trailer serving as support system for the backstop. Each of the sections of the 3 section unit are secured in the ground for safe use of the backstop and to eliminate any falling of the backstop during play. The backstop is also secured sufficiently to withstand baseball speeds of about 90+ miles per hour.In particular disclosed herein is a first and second planar fence sections. The first planar fence section is attached to a movable shaft. The movable shaft is pivotally connected to a first end of a trailer. The second planar fence section is attached to the first planar fence section, and the second planar fence section is movable with respect to the first planar fence section. A winch is fixed on a second end of the trailer for lifting the movable shaft from a first position to a second position. A pulley system is attached at the first end of the trailer. A cable wound over the winch is secured to the shaft through the pulley system. The portable baseball backstop assembly is easily transported with the trailer, and assembled for use at a variety of locations. The trailer serves to both secure the backstop and transport it to desired locations.

A method of adding refrigerant to an air conditioning system. The method includes measuring a first pressure inside of the air conditioning system and a second pressure inside of a container that holds refrigerant being added to the air conditioning system. The method also includes comparing the difference between the two measured pressures to empirical data in order to determine how long to pulse additional refrigerant into the air conditioning system. In addition, an apparatus configured to add refrigerant to an air conditioning system.
