English: SHeM images of a fly compound eye. All images were post processed by subtracting the median height difference between the rows so that the detector instabilities are not visible. (a) Large scale SHeM image of the entire eye with the red boxes indicating where the other two images are obtained. The image consists of 380 x 300 pixels, each with a size of 5 µm, that were measured with an initial pause of 0.5 s and a dwell time of 0.5 s at every point. (b) A high resolution image of the edge of the eye. The helium signal is highest when the surface normal points towards the detector. The image consists of 333 x 250 pixels, each with a size of 600 nm, that were measured with an initial pause of 0.5 s and a dwell time of 0.5 s at every point. (c) A composite image of the eye with a contaminant that creates a mask on the surface of the eye. Due to issues with the detector, three images have been combined together to produce a complete image. The image consists of 385 x 440 pixels, each with a size of 1 µm, that were measured with an initial pause of 0.5 s and a dwell time of 0.5 s at every point.
