8 points * Four 1-hour lecture/problem classes and one 5-hour laboratory class per week * First semester * Clayton * Prerequisites: PHS1011 and PHS1022, and one of MAT1010, MAT1050, MAT1811, MAT1910, and one of MAT1020, MAT1080, MAT1812, MAT1920; for Option B: PHS1031 and PHS1042, and one of MAT1050 or MAT1060
Objectives On the completion of this subject, students will be familiar with a range of instrumental techniques for physical or biophysical measurement. They will obtain a sound theoretical and practical grounding in a range of applied topics with an understanding of their appropriate uses and complete a number of experiments related to the theory which illustrate both the techniques and the applications.
Synopsis This subject is designed to introduce students to a range of techniques for physical or biophysical instrumentation and measurement. The subject consists of four units from the following lists. Option A units (1) Digital electronics: Logic operations, families and logic gates, Karnaugh maps. Combinational and sequential logic. Flip-flops, registers and counters. (2) Microprocessors: The 68000, bus organisation, interrupts and supervisor mode. 68000 programming, assembly and machine codes. Interfacing chips. (3) Electricity and magnetism: see description of this unit under PHS2011. (4) Acoustics, waves and applications: The acoustic particle, acoustic impedance. Spherical, plane and standing waves. Transmission and reflection at boundaries and barriers, frequency dependence. Resonance, sound generation in humans. Acoustic instruments, the ear, microphones, ultrasound, buildings and environmental noise, safety. Option B units (1) Image formation and vision: Image formation, lenses, mirrors. The eye. Instruments, microscopes, electron microscope, CCD's. Correcting for defects. Lasers, properties, uses and safety. (2) Radiation and its biophysical interactions: Types of radiation, interactions with matter, detectors. Characteristics and uses of radiowaves, microwaves, x-rays and gamma-rays. CT, MRI and PET. Radiation safety. (3) Acoustics, waves and applications: same as Option A unit. (4) Energy conversion and nature's metabolism: Energy conversions, energy flow. Phase changes. Engines and refrigerators, fuel cells. Solar radiation, food chains, biomass storage, fossil fuels, greenhouse effect. Body metabolism, heat regulation, clothing and shelter.
Assessment Examinations (4 x 1.5 hours): 67% * Laboratory work: 33%
