Precision instruments, metrology, fluorescence, low-noise analog electronics – that’s what we do.
SPIE Photonics West 2010
We’ll be teaching a ‘short course’ at the Photonics West 2010 show this January.
Fourier Transform of 1/f Noise
Here’s a curious article by Steve Smith, author of The Scientist and Engineer’s Guide to Digital Signal Processing, where he shows that 1/f noise is its own Fourier transform!
Radiometry Explained by NIST
The measurement of light is complicated by a variety of units and concepts that are not used in other fields.
Quantization Noise
We notice the assertion that A/D converter quantization noise is equal to ADU/SQRT(12), where ADU is the quantization unit or LSB.
Light Uniformity Testing
For both a clinical test microscope, and a home theater HDTV projection display, the light from the source must be quite uniform.
Custom Front Panels
Here’s a vendor we recommend, and a photo of some parts they made for us.
Low Noise NMR Design
Careful consideration of all the elements of a system’s design can lead you to some very improved performance.
Radiometric Measurements
It’s easy to confuse the units of LED light output. Steradians, luminous intensity, etc.
Image Analysis With (Free) ImageJ Software
Lately we’ve been able to use our digital camera to perform some nice measurements, through the help of a program called ImageJ.
Coffee Source
Multitasking through massive coffee consumption, we find this tasty, the Bizzarri Blend by Caffe Umbria.
US Energy Use Graph
To comprehend how much energy we use, and what goes where, this is great place to start.
