“…Due to a higher lateral scan velocity and a contactless measurement, these optical sensors provide an alternative to tactile stylus instruments. Fundamental advantages against often used optical full-field measuring topography sensors are a more compact geometrical setup, a high lateral scan range and a flexible sensor probe, enabling measurements at hard-to-access surface structures of the object under investigation [1][2][3][4]. A disadvantage compared to fullfield measuring sensors is that lateral scan axes are necessary to achieve the full surface topography to be measured by stitching single height values.…”

Point-wise measuring proﬁlometers like the tactile stylus instruments or optical sensors are established measurement tools in science and industry to measure and characterize surface textures. We present a ﬁber-coupled laser interferometric confocal distance sensor for surface proﬁling. The sensor is characterized by small geometric dimensions and by its high lateral scanning speed. The ability to measure specularly reﬂecting and rough surface textures are demonstrated by performing several measurements on a sinusoidal standard as well as two roughness standards speciﬁed by diﬀerent degree of roughness using various lateral scan velocities up to 75 mm/s. These measurement results are compared to those obtained by a tactile stylus instrument used in the identical measurement environment as the introduced optical sensor. Finally, the ability for full-ﬁeld measurements is presented.

Distortion product otoacoustic emissions (DPOAEs) measured from the ear canal can be a sensitive tool to detect changes in cochlear function over time. However, if multiplemeasurement procedures are to be useful clinically, testing needs to be reliable and sources of variability within individuals should be known. Herein, the influence of time-of-day (TOD), stimulus frequency, stimulus sound pressure level (SPL), and gender were evaluated on 2f1-f2 DPOAE amplitude in 16 adult volunteers with normal hearing. The effects of oral temperature and resting-pulse rate were also assessed. This study demonstrated a TOD main effect, with a period approximating one cycle-per-day. The magnitude of this effect averaged less than one dB and was not dependent on stimulus (frequency or SPL) or participant variables (gender, oral temperature, or resting-pulse rate), nor was it synchronized to a particular point-in-time. Stimulus level and gender effects on DPOAEs across frequency were also observed. Using generalizability theory (GT), DP iso-level/frequency profiles (DPILFPs) were found to be reliable measures within-subjects over a contiguous 24-hour time period. Significant and reliable between-subject differences were also documented. This study demonstrates the influence of stimulus and participant variables, quantifies the within-subject reliability over a 24-hour time period, and confirms that significant and reliable between-subject differences exist on DPOAEs across frequency, SPL, and gender.
