The OLÉ® Imager is an Overhead Lighting Environment (OLÉ) imaging system which emulates how the subject’s face is perceived by the human eye in everyday settings. The systems combines a high-resolution digital color camera with application-controlled xenon flash sources for standardized facial imaging.
The imaging system canopy provides overhead lighting that illuminates the subject's face with vertical and oblique raked light that mimics natural lighting and enhances topographical skin attributes (e.g., fine lines, wrinkles, and texture).
With no secondary reflections, the OLÉ Imager also provides better axis-based polarized lighting, used for analysis of sub-dermal skin attributes (e.g., pigmented spots). Industry standard perspectives of the face (frontal and oblique views) are captured by rotating the canopy around a stationary subject.
With open environment, raked and obliquely oriented illumination, the OLÉ Imager emulates how the subject's face is perceived by the human eye in everyday settings. Consistency and reliability of the imaging system is demonstrated using measurement of color standards within the captured image frame. Examples showing detection and measurement of wrinkles, fine lines, texture, and pores demonstrates the imaging system's capability in objectively evaluating the appearance of skin aging attributes. The OLÉ Imager will improve both visual and objective assessment of facial skin attributes in clinical studies.
White Light
Cross Polarized
Parallel Polarized
Color and intensity values for 8 Macbeth gray color standards were measured from white-light, cross-polarized, and parallel-polarized images (n=1,000).
Less than 1 gray level variation in median R,G,B values was observed across all lighting modalities. The standard deviation in light intensity for white-light, cross-polarized, and parallel-polarized images were 0.82, 0.73, & 1.13 respectively.
Quality of polarization evaluated as a ratio of median intensity measured on the reflective metal chip in cross and parallel polarized images indicates attenuation of spectral reflectance by a factor of 30.
Analysis scripts precisely detect, measure and count the photographic evidence in facial features, helping you substantiate claims and advance your research.
