multishot lensless camera development could aid disease diagnosis
2020/10/10
Researchers at Penn State are developing a new type of imaging that does not require a lens and uses reconfigurable particle-based masks to take multiple shots of an object. The technology i...
Development of Coherent Anti-Stokes Raman Scattering Microscopy
Nonlinear spectroscopy Ultra-fast laser Raman spectroscopy microscopy
2009/6/12
New multiphoton microscopy using CARS (Coherent Anti-Stokes Raman Scattering) spectroscopy is described. In CARS microscopy, the image of molecular vibration that is sensitive to the molecular spices ...
Nano-Processing of Transparent Materials by Focussed Femtosecond Laser Pulses for the Development of Novel Bio-Microchip
Femtosecond laser Silica glass Chemical etching
2009/6/8
We report fabrication of three-dimensional (3-D) microchannels inside transparent materials. The 3-D microfabrication was achieved by two steps. First, femtosecond pulses were focussed into the transp...
