An apparatus includes a glass element, a fluid, an illumination source, and an ultrasound emitter. The glass element is immersed in the fluid. The illumination source emits light. The ultrasound emitter is configured to direct an ultrasonic signal through the fluid to the glass element. The glass element is configured to reflect the ultrasonic signal along a substantially similar path as an optical path that the light propagates along.

Common axis for optical and acoustic signals

A laser device includes a seed laser, a plurality of optical amplifiers, and an optical distribution assembly. The seed laser is configured to emit seed laser light. The plurality of optical amplifiers is configured to generate amplified laser light by amplifying the seed laser light. The optical distribution assembly is configured to distribute the seed laser light to an input of each of the optical amplifiers in the plurality and each of the optical amplifiers is configured to direct its respective amplified laser light to a common target.

Multi-channel laser

An enclosure permits ingress of an infrared light beam and ultrasonic signal entering the enclosure from two different locations and facilitates their exit from the enclosure along a substantially similar egress path. The enclosure contains fluid which propagates the ultrasonic wave and a glass element which reflects the ultrasonic wave from its ingress direction onto an egress path. The fluid is an index matching fluid having a refractive index the same as the refractive index of the glass element, rendering the glass element transparent to the infrared light beam. Thus, the infrared light beam, having been induced into the enclosure on an entry path directed through the glass element, passes through the glass element without being reflected or refracted by it, placing the infrared light beam on a substantially similar path to that of the ultrasonic wave for egress of both waves from the enclosure at substantially the same point.

Apparatus for directing optical and acoustic signals

A system or device includes a member structure, a plurality of flexible members, and a plurality of tips disposed at ends of the flexible members. The member structure includes an ultrasonic emitter configured to emit an ultrasonic imaging signal. The plurality of flexible members are coupled to the member structure. The plurality of tips are disposed at ends of the flexible members. At least one tip of the plurality of tips includes an image sensor configured to receive an infrared exit signal.

Flexible tip optical imaging

A refractive component includes at least one reflection surface and at least one diffractive optical element. The refractive component is configured to receive a light beam and the light beam expands within the refractive component and is reflected by the at least one reflection surface. The diffractive optical element is configured to receive the light beam reflected from the at least one reflection surface, collimate the light beam, and redirect the light beam out of the refractive component.

Expanding beam optical element

A device includes a sensor, a coherent infrared illumination source and optics to direct an infrared reference beam to the sensor. The sensor is positioned to capture an image of an interference signal generated by an interference of the infrared reference beam and a wavelength-shifted exit signal. The wavelength-shifted exit signal propagates through the optics before interfering with the infrared reference beam.

Interference optics for optical imaging device

A light pulse is emitted from a light source for illuminating a medium. Energy level data of the light pulse is measured before the light pulse enters the medium. An image sensor captures an image that includes an interference pattern generated by an exit signal of the light pulse exiting the medium interfering with a reference wavefront. Normalized intensity data is generated by normalizing intensity data exit signal data by the energy level data.
