Abstract

We present a practical laser speckle imaging device for skin cancer detection based on a 980 nm source and black silicon camera technology, with superior penetration depth and contrast. By operating at 980 nm we obtain deeper perfusion contrast and are immune to differences in skin pigmentation. The use of a black silicon camera ensures a high quantum efficiency without significantly increasing the cost and complexity of the device. We will show the effectiveness of the device in imaging different skin lesions and discuss the system specifications (wavelength, power, exposure time, frame rate, and processing algorithm) that led to the optimal contrast.
