Abstract
An apparatus includes a shaft, an imaging head, and a processor. The shaft includes a distal end sized to fit through a human nostril into a human nasal cavity. The imaging head includes an image sensor assembly, a plurality of light sources, and a plurality of collimators. At least some of the light sources are positioned adjacent to the image sensor assembly. Each collimator is positioned over a corresponding light source of the plurality of light sources. The processor is configured to activate the light sources in a predetermined sequence. The image sensor assembly is configured to capture images of a surface illuminated by the light sources as the light sources are activated in the predetermined sequence.

An apparatus comprising:
- (a) a shaft defining a longitudinal axis, the shaft including:
- (i) a proximal end,
- (ii) a distal end, the distal end of the shaft being sized to fit through a human nostril into a human nasal cavity, and
- (iii) a flexible portion;
- (b) an imaging head positioned at the distal end of the shaft, the imaging head including:
- (i) a first image sensor assembly,
- (ii) a plurality of light sources, at least some of the light sources being positioned adjacent to the first image sensor assembly, the light sources being configured to be activated in a predetermined sequence, and
- (iii) a plurality of collimators, each collimator being positioned over a corresponding light source of the plurality of light sources, each collimator defining an aperture centered on a corresponding collimator central axis that is transversely oriented relative to the longitudinal axis of the shaft, each collimator being positioned to collimate light from the corresponding light source along the collimator central axis;
- and
- (c) a processor in communication with the imaging head, the processor being configured to activate the light sources in the predetermined sequence, the first image sensor assembly being configured to capture images of a surface illuminated by the light sources as the light sources are activated in the predetermined sequence.
