Abstract

We demonstrate a simple and cheap method for phase shifting that does not need additional devices. A small beam offset at the fast scanning mirror introduces a causal phase shift which can be used for recently introduced B-scan based complex image reconstruction as well as for enhancing flow signals with resonant Doppler imaging. It can be directly implemented in any FDOCT setup without additional cost. The method is demonstrated on human skin in vivo for spectrometer based FDOCT operating at 1300nm employing a handheld scanner. The latter includes the reference arm and is equipped with a single point scanner.

Marginal cost

In economics, the marginal cost is the change in the total cost that arises when the quantity produced is incremented, the cost of producing additional quantity. In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount. As Figure 1 shows, the marginal cost is measured in dollars per unit, whereas total cost is in dollars, and the marginal cost is the slope of the total cost, the rate at which it increases with output.

Total cost

In economics, total cost (TC) is the minimum dollar cost of producing some quantity of output. This is the total economic cost of production and is made up of variable cost, which varies according to the quantity of a good produced and includes inputs such as labor and raw materials, plus fixed cost, which is independent of the quantity of a good produced and includes inputs that cannot be varied in the short term such as buildings and machinery, including possibly sunk costs.

Cost curve

In economics, a cost curve is a graph of the costs of production as a function of total quantity produced. In a free market economy, productively efficient firms optimize their production process by minimizing cost consistent with each possible level of production, and the result is a cost curve. Profit-maximizing firms use cost curves to decide output quantities. There are various types of cost curves, all related to each other, including total and average cost curves; marginal ("for each additional unit") cost curves, which are equal to the differential of the total cost curves; and variable cost curves.
