Abstract: Embodiments of the present invention may be used to perform measurement of surfaces, such as external and internal surfaces of the human body, in full-field and in 3-D. Embodiments of the present invention may include an electromagnetic radiation source, which may be configured to project electromagnetic radiation onto a surface. The electromagnetic radiation source may be configured to project the electromagnetic radiation in a pattern corresponding to a spatial signal modulation algorithm. The electromagnetic radiation source may also be configured to project the electromagnetic radiation at a frequency suitable for transmission through the media in which the radiation is projected. An image sensor may be configured to capture image data representing the projected pattern.

Abstract: Systems and methods are disclosed for making three-dimensional models of the inside of an ear canal using a projected pattern. A system comprises a probe adapted to be inserted into the ear canal. The probe comprises a narrow portion adapted to fit inside the ear canal and a wide portion adapted to be wider than the ear canal, which may be formed by a tapered stop. An illumination subsystem projects a pattern of light from the distal end of the probe onto a surface of the ear canal, the pattern being modulated by the three-dimensional surface of the ear canal. An imaging subsystem captures a series of individual images of the pattern of light projected onto the surface of the ear canal. A computer subsystem calculates digital three-dimensional representations from the individual images and stitches them together to generate a digital three-dimensional model of the ear canal.

Abstract: Embodiments of the present disclosure may utilize one or more spatial sensors, such as an accelerometer, gyroscope, and/or IMU, in providing position and/or orientation data for continuous real-time, full-field, and three-dimensional (“3-D”) surface data maps. An electromagnetic radiation source is configured to project electromagnetic radiation onto a surface. An image sensor is configured to capture image data representing the projected pattern as reflected from the surface. One or more spatial sensors are used to provide coordinate data for providing the position and/or orientation information. Using the coordinate information, an image processing module may be configured to stitch together the individual full-field 3-D data frames into a complete representation of the surface under study.

Abstract: The invention provides a device for shifting the phase of a projected grating by use of a grating generator comprising one or more clear substrates having a plurality of equally-spaced, equal width bands of liquid crystal. The liquid crystal bands are selectively activated to modulate, that is, to shift, the phase of the projection of the grating on a test surface.
