This function electrically boosts the light sensitivity when there is insufficient illumination on the object. You can set the gain of the video amplifier according to the brightness of the object. Select the setting mode according to your shooting conditions.

“Our goal is to make OCT drastically less expensive, so more clinics can afford the devices, especially in global health settings,” said Wax

You can switch to the Auto Gain mode by setting the items in [Camera Function] [GAIN L], [GAIN M], and [GAIN H] to “ALC”.

Optical Coherence Tomography is the light-equivalent to SONAR, sending signals to, then reflecting off of surfaces in order to measure depths of individual layers. Those collective signal measurements form an image of the retinal layers, where eye diseases quietly lurk, and can be accurately detected. Although OCT has been available for over 25 years, it remains an expensive technology to manufacture and operate. The use of high-quality optics, precision components and complex software have put this technology out of reach for most healthcare providers worldwide.

The camera recorder switches to the Auto Gain Adjustment mode (fixed at “ALC”), and the gain of the video amplifier is automatically set according to the brightness of the subject.In this case, the [GAIN L/M/H] selection switch on the camera recorder is disabled.

Lumedica Vision was founded by an experienced team of engineers including Chief Scientist Dr. Adam Wax from the Pratt School of Engineering. Dr. Wax’s team has developed a new low-cost optical coherence tomography (OCT) scanner that could dramatically extend the impact of the imaging technology for eye health by making eye imaging more affordable, accessible and easier to use. Affordable access would enable more health care providers to conduct OCT imaging, giving patients greater, earlier access to the one test that can save their vision and improve their quality of life.

You can change the gain value of each position in the menu. Increasing the sensitivity causes the screen to appear grainier.

When [Camera Function] [FULL AUTO] [Gain] is set to “SW Set”, the gain value can be altered using the [GAIN L/M/H] selection switch even when the [FULL AUTO] switch on the camera body is set to “ON”.

The key to the cost reduction is the innovative spectrometer design. This approach takes light on a circular path – rather than the conventional combination of lenses, mirrors and precision diffractive optics. The overall result is a product which reduces the typical weight of a clinical OCT system from 50-70 pounds down to just 4 pounds, while cutting the cost from at least $60,000 to less than $14,000.
