    Abstract: In part, the disclosure relates to shadow detection and shadow validation relative to data sets obtained from an intravascular imaging data collection session. The methods can use locally adaptive thresholds and scan line level analysis relative to candidate shadow regions to determine a set of candidate shadows for validation or rejection. In one embodiment, the shadows are stent strut shadows, guidewire shadows, side branch shadows or other shadows.

    Abstract: In part, the invention relates to methods, devices, and systems suitable for controlling a light source. The light source is configured for use in a data collection system such as an optical coherence tomography system. The light source can be controlled with a drive waveform. Linearizing and symmetrizing parameters of the light source such as forward and backward scan durations is achieved using a suitable drive waveform. Phase, amplitude, and other parameters for different harmonics of a fundamental wave can be identified that improve operating parameters such as the duty cycle and peak frequency matching between scans. The fundamental wave and one or more of such harmonics can be combined to generate the suitable drive wave form. The light source can include a tunable light source that includes or is in optical communication with a tunable filter.

    Abstract: In one embodiment of the invention, a semiconductor optical amplifier (SOA) in a laser ring is chosen to provide low polarization-dependent gain (PDG) and a booster semiconductor optical amplifier, outside of the ring, is chosen to provide high polarization-dependent gain. The use of a semiconductor optical amplifier with low polarization-dependent gain nearly eliminates variations in the polarization state of the light at the output of the laser, but does not eliminate the intra-sweep variations in the polarization state at the output of the laser, which can degrade the performance of the SS-OCT system.

    Abstract: In at least one embodiment of the wavelength-tunable light source (1), it comprises an output source (2), which is capable in operation of generating electromagnetic radiation (R). Furthermore, the light source (1) has a wavelength-selective first filter element (5), which is situated downstream from the output source (2). Moreover, the light source (1) contains a first amplifier medium (3), which is situated downstream from the first filter element (5) and is capable of at least partial amplification of the radiation (R) emitted by the output source (2). The light source (1) further comprises at least one wavelength-selective second filter element (6), which is situated downstream from the first amplifier medium (3), the second filter element (6) having an optical spacing (L) to the first filter element (5). The first filter element (5) and the at least one second filter element (6) are tunable via a control unit (11), which the light source (1) has. The filter elements (5, 6) are tuned for this purpose so that first filter element (5) and second filter element (6) are transparent to a partial radiation (P) of the radiation (R) in a time delay (T) to one another, the delay (T) being equal to the quotient of the optical spacing (L) and the speed of light in vacuum (c).
