I was talking to
Lenore McMackin ( the President & CTO at
InView Technology Corporation, the company behind the
single pixel IR camera) the other day and found out that they were releasing a streaming light modulators (InView223 and InView223-A ). The issue that is being addressed here is that DMD based light modulators generally go for a batch mode of sorts. This solution seems to allow a continuous streaming of patterns through the DMD.
From the announcement:
InView Technology Corporation Releases
Streaming Spatial Light Modulator Engine. The InView223 provides a
streaming alternative to batch-mode DMD development kits using a
high-speed PCI Express 2.0 generation 2 by 8 interface. Start your light
modulation project with the fastest engine available. https://lnkd.in/ebWrrFp
The product is on their site here. From that page:
InView223 – Controllable Spatial Light Modulator System
The InView223 is a high-speed, visual wavelength Spatial Light
Modulator (SLM) system made for immediate integration into benchtop
experiments. The InView223 gives researchers the ability to apply novel
1024×768 modulation patterns to an XGA resolution digital micro-mirror
device with full electronic functionality to easily test novel
modulation patterns for Compressive Sensing, computational photography,
structured illumination and a host of other dynamic light modulation and
control applications.
The InView223 provides a streaming alternative to batch-mode DMD
development kits. Arbitrary mirror patterns are continuously loaded into
the SLM using a high-speed PCI Express 2.0 generation 2 by 8 interface.
The SLM’s FPGA does not waste time or memory storing these externally
generated patterns but immediately loads the newly received patterns
onto the DMD.
The InView223 is available in two configurations: the InView223-A
with flexible DMD mount, and the InView223-B with a fixed front plate,
PCB housing, and sensor mount.
The minimal mechanical construction of the InView223-A provides full
access to control electronics and optical access to the SLM at both
mirror-switching positions. A 12’” flexible ribbon cable allows freedom
in positioning the DMD carrier board that comes with mounting holes for
securing it to your mount. Its low profile hardware provides full
optical access to the DMD face over a 150º wide cone and freedom for
mounting in a variety of positions on the optical bench.
The InView223-B is designed to isolate the modulated optical signal
to one of the mirror-switching positions in a compact optical path. The
InView223-B features a fixed front plate, total internal reflection
prism, off-axis optical blacking, and a sensor mount for quick hardware
integration.
Included with both the InView223 models are:
1) A Texas Instruments DLP® .7 XGA 2xLVDS 12o Type A 1024×768 digital micromirror device (DMD)
2) Controller boards with FPGA-based pattern generation PCB with PCIe connector.
3) Output trigger signal to allow the user to synchronize data acquisition with the mirror flips.
4) Linux PCIe device driver and user mode API for streaming patterns across the PCIe bus.
Optionally, InView can supply a set of modulation patterns to get you
started developing your own compressive sensing application.
