This core module develops scientific knowledge relating to understanding the psycho-physics of the visual processes and the processes of visual function. Students will become familiar with clinical psycho-physical techniques and tests. Students will gain an understanding of normal colour discrimination and types and characteristics of colour vision defects.
Photometry: definitions and measurement of photometric and radiometric quantities, photometric equations.
Colorimetry: colour mixing, colour triangles, colour specification using CIE and Munsell systems, standard illuminants, colorimeters.
Psychophysical methods and psychometric function
Absolute and difference thresholds, sensitivity, luminance/brightness relationships.
Dark and light adaptation: measurement, parameters and mechanisms; photopic, mesopic and scotopic vision; relative luminous efficacy, CIE Vl functions.
Temporal and spatial summation, resolution and contrast sensitivity functions
Normal colour discrimination. Theories of colour vision. Spectral absorption properties of cones. Types and characteristics of colour vision defects.
Principles and designs of colour vision tests.
Lectures, laboratories, tutorials, self-directed learning, scenario-based learning (SLB), group project work, peer assessment, presentations E-learning.
