Poster Title

P-47 Design of a Prototype Clinical Near Infrared Imager

Abstract

A prototype near infrared imaging device is needed for research in the medical field. The design needed careful planning to complete the prototype. The prototype needed to include: a polarized camera, near infrared LEDs, focusing lasers, triggering switches, and a microprocessor. The near infrared LEDs require a very specific current threshold to prevent false readings and skewing the data. Simple resistors were not accurate enough to maintain this exact amount of current. Research into various current control devices led to the decision to implement LED drivers. This discovery expedited the design process by giving the circuit design a base. Additional components could be selected to work with the drivers.
