An ultrasound emitter launches an ultrasonic signal into a diffuse medium such as tissue. The diffuse medium is illuminated with an infrared illumination signal. activating an ultrasound emitter to launch an ultrasonic signal into a diffuse medium. An infrared reference beam is interfered with an infrared exit signal having an infrared wavelength that is the same as the infrared illumination signal. An infrared image is captured of the interference of the infrared reference beam with the infrared exit signal.

Optical imaging with unshifted reference beam

An image pixel array captures and infrared image of an interference between an imaging signal and a reference wavefront. A display pixel array generates an infrared holographic imaging signal and the image pixel array receives the infrared imaging signal through the display pixel array.

Optical imaging through display

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

An imaging system includes an infrared illuminator, an ultrasonic emitter, a reference wavefront generator, and an image pixel array. The infrared illuminator emits a general illumination emission into a three-dimensional diffuse medium, where a portion of the general illumination emission encounters a voxel within the diffuse medium. The ultrasonic emitter focuses an ultrasonic signal to the voxel to wavelength-shift the portion of the general illumination emission to generate a shifted infrared imaging signal. The reference wavefront generator generates an infrared reference wavefront having a same wavelength as the shifted infrared imaging signal. The image pixel array captures an infrared image of an interference between the shifted infrared imaging signal and the infrared reference wavefront.

Optical imaging with ultrasonic signal

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.

Pulse measurement in optical imaging

An infrared image is captured by an image sensor and a frequency domain infrared image is generated by performing a Fourier transform operation on the infrared image. A filtered frequency domain infrared image is generated by applying a mask to the frequency domain infrared image. A spatial domain infrared image is generated by performing an inverse Fourier transform on the filtered frequency domain infrared image. Phase data is extracted from the spatial domain infrared image and a holographic pattern generated from the phase data is driven onto a display.

Optical transformation device for imaging

An imaging device includes an image pixel array and a display pixel array. The image pixel array is configured to capture an infrared image of an interference between an infrared imaging signal and an infrared reference wavefront. The display pixel array is configured to generate an infrared holographic imaging signal according to a holographic pattern driven onto the display pixels. The holographic pattern is derived from the infrared image captured by the image pixel array.

System and device for optical transformation

An infrared image is captured while an infrared reference wavefront and an infrared imaging signal are incident on an image pixel array. A frequency domain infrared image is generated by performing a transform operation on the infrared image. A filtered frequency domain infrared image is generated by applying a mask to the frequency domain infrared image to isolate a frequency representing the interference between the infrared reference beam and the incoming infrared image signal. Intensity data is generated from the filtered frequency domain infrared image. The intensity data is incorporated as a voxel value in a composite image.
