Abstract: A self-mixing interferometer configured to monitor particulate material within a monitored region of space comprising a laser cavity assembly (1A) and an optical assembly (1B) configured to bathe the monitored region with laser light of the interferometer. A laser monitoring unit (1C) is configured to acquire an interferometric signal generated by the interferometer in response to light returned to the laser cavity assembly from said wavefronts by said particulate material. A processing module (1D) is configured to determine a property of the particulate material within the monitored region according to a wavelet transformation of the interferometric signal at least a part of which comprises a waveform of changing frequency.

Abstract: An oral treatment device includes intraoral image sensor equipment configured to generate image data representing at least a portion of the oral cavity of a user during use by the user of the oral treatment device. The oral treatment device includes a controller configured to process the generated image data to determine location data indicating a location of an interproximal gap between adjacent teeth in the oral cavity of the user. The controller is configured to process the generated image data using a trained classification algorithm configured to identify interproximal gaps, the trained classification algorithm having been trained prior to the use of the oral treatment device. The controller is configured to, during the use of the oral treatment device, control the oral treatment device to deliver a treatment to the detected interproximal gap based on the location data.
